[00:02:56] <BrokenClockwork> adimit: This is nice to hear, after 1 semester Haskell I am really tensioned for learning Java
[00:03:58] <adimit> BrokenClockwork: heh, the Java Generics system is sort of trying to simulate Haskell's typeclasses (Philip Wadler, one of the main persons behind Haskell, originated it), but it's got some limitations compared to Haskell.

[00:04:21] <dmlloyd> nah, it's its own thing.
[00:04:33] <adimit> BrokenClockwork: and ghc is in *so* many ways superiour to javac. I'd love to see type inference in Java...

[00:04:56] <ayrnieu> no, they are not alike.
[00:05:04] <BrokenClockwork> mh
[00:05:23] <redrebel> if I have strings like this-> "com.sample.Users[uid=22]" what is the best way extract 22?

[00:10:29] <RLN> ayrnieu and?
[00:10:35] <RLN> what relevance does my spelling have?
[00:11:11] <Kalianyia> Is there a way to see what the current text for a JTextField is in the eclipse debugger? When I have it open in the eclipse debugger, there is no text field nor any field that I can see that displays what the current text value is. There are about 60 other fields that are part of JTextField that I can see however.

[00:14:02] <adimit> Kalianyia: I have no direct answer, but it's gotta be in the fields somewhere. Eclipse's debugger has a way of hiding things that are deep down some hierarchy. You could maybe read the JTextField source to see which field it is, and then find that same field in the debugger.
[00:14:08] <lyy> java is the most popular???? wow!

[00:16:39] <lyy> cool!
[00:16:41] <bimbo> jogl rocks
[00:16:48] <adimit> RLN, sorry I misunderstood your statement.
[00:16:49] <lyy> what's jogl?
[00:17:06] <bimbo> does anybody knows why java uses signal 11 for communication purposes? or maybe it's not communicating but actually segfaulting? I've got a dtrace script (solaris) that catches signals and does some operations based on them, java uses a lot the SIGSEGV signal (11), why is that?
[00:17:06] <jonaslund> bimbo: altho from what i've seen the ones doing commercial stuff has used lwjgl
[00:17:10] *** zacs7 has joined ##java
[00:17:18] <bimbo> jonaslund: yeah, but that's on top of jogl
[00:17:25] <lyy> what's lwjgl?
[00:17:28] *** zacs7 has left ##java
[00:17:32] <bimbo> jogl are the java opengl bindings
[00:17:38] <lyy> ahhhh
[00:17:38] <AMcBain> ~~lyy jake2
[00:17:38] <javabot> lyy, jake2 is an excellent implementation of the id Software Quake 2 engine in Java, distributed via JWS for instant Strogg killing gratification: http://bytonic.de/html/jake2.html
[00:17:40] <lyy> cool stuff
[00:17:47] <jonaslund> bimbo: umm.. sure of that ? afaik it's a separate set of bindings
[00:17:49] <bimbo> and yes, jake2 is incredibly fast

[00:18:50] *** jottinger has quit IRC
[00:18:50] <lyy> but if java does them just as well, I'll try it
[00:19:19] <RLN> in all honesty i don't consider java's 3d capacity to be anywhere near c or c++
[00:19:24] <jonaslund> bimbo: then why does wikipedia mention them as separate, and why would jake2 have 2 separate bindings if lwjgl used jogl ?!
[00:19:27] <RLN> mostly due to speed
[00:19:47] <lyy> speed is top priority
[00:19:48] <bimbo> RLN: speed is not a problem in java with jogl, read a bit about it
[00:19:50] <lyy> :(
[00:19:56] <lyy> cool
[00:19:58] <RLN> i have never used jogl
[00:20:23] <RLN> though i've seen some 3d java games, and they are weak
[00:20:27] <jonaslund> "3d capacity" is just a matter of so much less code being developed on java for 3d
[00:20:49] <RLN> sorry i used the wrong word to desscribe it
[00:21:01] <jonaslund> RLN: if you're only looking for far-cry maybe.. but even those games are usually limited by shaders and the graphics cards mostly nowadays

[00:23:33] <ayrnieu> bimbo - sigsegv are probably intentional, in the GC or normal memory management.  I know that CMUCL and SBCL (Common Lisp implementations) do this, but I forget the details and I haven't found a nice summary of the technique.

[00:24:33] <bimbo> jonaslund: I guess I was mistaken, I was sure I read somewhere that lwjgl was sitting on top of jogl, but I can't find that anywhere
[00:24:41] <lyy> jogl right?
[00:24:44] <jonaslund> http://tribaltrouble.com/screenshots?id=18 <- done in java
[00:24:50] <kab> AMcBain you can do it very simple, with some regexp like this str.replaceAll(".*\\[uid=(\\d+)\\]", "$1")
[00:24:54] <lyy> jonaslund: thanks
[00:25:00] <RLN> jonaslund
[00:25:05] <jonaslund> bimbo: if you look at the api it's different aswell
[00:25:19] <RLN> do you think that even touches c/c++ honestly?
[00:25:23] <bimbo> ayrnieu: hmmm I see, yeah I've been noticing not only java but firefox for example use sigsegv too a lot
[00:25:26] <RLN> that is pretty bad lol
[00:25:27] <AMcBain> kab: but I think, for him, it would be better if he was using something that *he* knew how it worked and why.
[00:26:00] <kab> AMcBain, that's another thing, but RegExp are friendly :)
[00:26:18] <AMcBain> kab: maybe, I know how to use them, and thought about recommending it, but he needed something easy.
[00:26:24] <jonaslund> RLN: the only thing that java is seriously worse than c++ at is GC'ing (if you fuck up) and vector operations
[00:26:28] <AMcBain> s/easy/understandable/
[00:26:40] <RLN> well that goes back to the speed issue does it not?
[00:26:43] <bimbo> jonaslund: yes, I thought I'¿ve read that lwjgl was only a consolidation of jogl and openal, but it's a consolidation of opengl (new bindings I guess) and openal (along with some other input device support)

[01:12:54] <SummerWO> Can I make an argument to a function a bounded wildcard?  I want my argument to be: public List<Type> getAll(<? extends Shape> shape) { } ...  But that's a syntax error.  Can I do something like this?
[01:12:58] <jottinger> toplink essentials was the first JPA implementation. AFAIK, there are no "pure JPA" implementations.
[01:13:40] <svm_invictvs> pure JPA?
[01:13:53] <svm_invictvs> as in nobody implementes the spec fully?
[01:13:55] <svm_invictvs> ~jpa
[01:13:55] <javabot> JPA is the Java Persistence API. For all intents and purposes, it's meant for persisting objects into a relational database, which is usually correct but let's be real, that's sometimes stupid. Lots of implementations of this - Hibernate, cocobase, Toplink Essentials, openJPA are some. Wanna learn more? Google, or read http://java.sun.com/developer/technicalArticles/J2EE/jpa/
[01:14:12] <svm_invictvs> That sounds like a cheeser factoid

[01:14:51] <jottinger> svm_invictvs: "pure JPA" meaning something that implements the spec and nothing else but the spec
[01:14:55] <SummerWO> Anyone?
[01:14:56] <svm_invictvs> I see.
[01:15:04] <jottinger> Every JPA impl adds to the spec in various ways.
[01:15:34] <jottinger> There are multiple implementations of JPA that are "full JPA" but none that contain ONLY JPA.
[01:15:40] <svm_invictvs> ugh, I've gotta figure out an excuse to work late next friday
[01:15:42] <SummerWO> public List<Type> getAll(List<? extends Shape> shapes) {} works..  But I don't want a List passed it; I just want one.
[01:16:37] <svm_invictvs> SummerWO: eh?
[01:16:51] <reverend> SummerWO: what about just getAll(Shape shape) ?
[01:16:52] <SummerWO> svn: I want to pass a bounded wildcard as an argument..
[01:16:58] <svm_invictvs> oh
[01:17:06] <SummerWO> I want the argument to be a subclass of Shape, but not a Shape.
[01:17:06] <svm_invictvs> Class<T ? extends Shape>?
[01:17:06] <jottinger> why would you not... do what reverend said
[01:17:10] <svm_invictvs> I see.
[01:17:11] <svm_invictvs> oh
[01:17:11] <reverend> SummerWO: so make it abstract
[01:17:13] <SummerWO> Oh, Class?
[01:17:15] <jottinger> SummerWO: is shape abstract?
[01:17:17] <svm_invictvs> nevermind
[01:17:32] <SummerWO> Shape is abstract.
[01:17:41] <reverend> then there's no problem

[01:18:01] * jottinger gives up
[01:18:06] <SummerWO> Ah, yes, good point.  Class<? extends Shape? works too..  Is the abstract class preferred?
[01:18:15] <SummerWO> Thank you.

[01:20:24] <SummerWO> It was an example.
[01:20:37] <tazle> (I atually though he was talking about them at first)
[01:22:01] <Drizzt321> I have a loop and pulls ORDER BY RAND() LIMIT 10 records from a specific table each iteration. While the loop is running (sleeps for ~1sec between each select) I put in an API call into the system which puts data into the table. When I look manually I see that the data is in the table, but while printing out the results each time through I don't see any new data at all. I tried clearing out...
[01:22:03] <Drizzt321> ...the table, and putting in a couple of records while the loop was running, but still didn't get anything. Any ideas?

[02:54:20] <dmlloyd> I like transfer objects, though they often end up being the most typing
[02:54:26] <dmlloyd> I like that they're strongly-typed
[02:54:37] *** Nilbus has left ##java
[02:55:17] <Gevaudan82> dmlloyd: i can live with transfer objects, BeanUtils has utilities from reflectivly copying properties from TOs to entities...so if that is your preference, my next question is...
[02:55:39] *** HockeyInJune has joined ##java
[02:56:35] <Gevaudan82> should the UI pass in a single "transaction" TO made up of smaller TOs modeled after the middle layer's entity structure? the middle layer keeps no state and knows nothing about where the user is in the flow, thus must be able to handle partial or complete data
[02:57:26] <dmlloyd> as a general rule, I'd say that if the middle layer is stateless then a request to the middle layer must encompass as much of the transaction as must be atomic

[03:01:19] *** durka42 has quit IRC
[03:01:42] <Gevaudan82> interesting...the application i'm discussing currently uses the map approach (map of map of string fields) where the UI packs and the MT builds entities...the rules rely solely on these string fields whereas everything else relies on the entity objects which are derived from the map
[03:01:59] *** john_|away is now known as The_Birdman
[03:02:39] <Gevaudan82> for small projects I like the hibernate entity object approach...in hibernate in action they make a good case for doing away with TOs...then again for enterprise applications I agree, TOs likely make the most sence out of the three (unless there is another option)
[03:03:47] <Gevaudan82> the map of map of strings approach makes debugging a nightmare and the the MT must take always be in sync with the UI...for example if the UI packs 01/01/2008 the MT better parse it correctly into a Calendar or Date object

[03:17:30] <svm_invictvs> I never thought about this.
[03:17:52] <svm_invictvs> But, if a base class has a syncyhronized method, and you overrride it, the subclass method is not synchornized, right?

[03:29:06] <svm_invictvs> http://rafb.net/p/kqI7aT81.html
[03:29:08] <Gevaudan82> moot point i guess...like deciding between using a static init() method to initialize a static collection or a static block (i.e. static {colllection = new ....})
[03:29:08] <svm_invictvs> So yeah
[03:29:36] <svm_invictvs> there's a big difference between static final int foo = 42; and using a static block.
[03:30:16] <Gevaudan82> how so?
[03:30:18] <svm_invictvs> Oh I see, what you mean.
[03:30:41] <svm_invictvs> Gevaudan82: runtime vs compile time.
[03:32:25] <Gevaudan82> svm_invictvs: i get that...but say I have a map<Key, Value> that I use solely for the contains method so I don't have to have conditional logic...it seems a wash whether i initialize it in a static block or in the declaration...if the member variable is solely going to be used for that purpose

[03:43:24] <wans> so.. i should read it as String, then convert it to a char[] and finally double?
[03:43:26] <Gevaudan82> just expose the method you need... BigDecimal nextBigDecimal() and under the covers do what cheeser said, read it as a string and convert it accordingly
[03:43:33] <lorbrito> not

[03:46:17] <jsquared> is there a difference between "public <T> void foo(Bag<T> b) {...}" and "public <?> void foo(Bag<?> b) {...}", assuming I never use any details in foo about Bag's type parameter?

[03:48:14] <Gevaudan82> wans: so expose a method or class that does so? Scanner shouldn't be a part of your API....use scanner under the covers in a package scoped class...expose a public interface that does what you want

[05:01:10] <Seldon75> HeatHawk[AP2]: does it return null, or an empty list?
[05:01:40] <Seldon75> try using forward slashes in the path
[05:02:07] <Gevaudan82> Deiselton: i've never used the API nor do I know exactly which API you are referring to...I would imagine you can just recreate the Object which would allow you to call start like it was the first time it was played
[05:02:21] <HeatHawk[AP2]> well the check is for > 0 , but forward slashes should break it
[05:02:39] <Seldon75> why would forward slashes break it?

[05:03:10] <Deiselton> i tried but it instead just tries to play form the end point when i stopped it... which is the end of the file... im thinking the .reset() in the inputstreamer class will fix it.. trying now.. jsut ran into it
[05:03:17] <HeatHawk[AP2]> windows doesnt use forward slashes?
[05:03:24] <Seldon75> HeatHawk[AP2]: wrong
[05:03:38] <Seldon75> its just that other o/ses dont use backslashes
[05:03:49] <Seldon75> windows understands both
[05:04:01] <Gevaudan82> there is System.getProperty("file.separator") which will give you the platform independent separator
[05:04:11] <Seldon75> ..but / works regardless

[06:26:16] <HeatHawk[AP2]> Fanook, we had it the same time as compilers, it was a lot of work writing a compiler in c from scratch - the gui courses felt like a joke
[06:26:46] *** ScottG489 has joined ##java
[06:26:58] <Fanook> I first encountered real gui programming (i don't count VB) in my OOP course, where we wrote a simple drawing app

[06:27:18] <Fanook> that was...3rd semester i think?
[06:27:46] <HeatHawk[AP2]> Fanook, VB never counts, we did GDI + Direct X in c/ c++
[06:27:55] <Fanook> no no, 4/5. 3rd year
[06:29:01] <Fanook> I saw a little of the windows api in a systems programming course (was supposed to be low-level stuff, turned out to be a course on the windows api). There be some ugly calls in that jungle

[07:19:55] <ilyak> not getting certs
[07:19:58] <Fanook> what happens when I get bored? http://www.papernapkin.org/pastebin/view/4319/ happens when I get bored
[07:20:11] <illbeatu> certification is so gay.
[07:20:27] <kochii> well, it wont be so gay when you go to your interview
[07:20:34] <illbeatu> assuming you get one?
[07:20:44] <Fanook> assuming they care
[07:20:46] <deebo> its even gayer in the interview if the interviewers know their shit :P
[07:20:56] <deebo> certificates are a nice way of hiding the fact you have no experience :P
[07:20:58] * ilyak thinks you better have some experience than just certs
[07:21:03] <ilyak> they are paper, after all
[07:21:26] <ilyak> Also, I think they teach wrong things there
[07:21:29] <kochii> lol...ok if you think so. seems you have a very good experience in the job world
[07:21:43] <deebo> there are really few things that certificates are good for, and none of them apply to coding imo
[07:22:03] <deebo> most of them are for like people that deal with really specific hardware
[07:22:09] <ilyak> certs are fine for software and hardware that you can't grab
[07:22:15] <ilyak> Like expensive ciscos

[07:48:52] <ramdam> dangertools, why can't i put the .so in the jar and programmatically tell it to fetch it from inside there
[07:49:01] <pr3d4t0r> Fanook: I'm not sure if it's public knowledge.  But yeah, he works there.

[07:49:25] * ramdam is frustrated
[07:49:33] <dangertools> ramdam: unpack it and use System.load() or tell java.library.path where the file will be when you unpacked it
[07:50:00] <pr3d4t0r> ramdam: When it comes to Linux systems your configurations may be all over the place, depending on distribution and sysadmin whims.
[07:50:21] <ramdam> oh man
[07:50:23] <pr3d4t0r> ramdam: The sanest thing to do is to document all the requirements (regardless) and, if you can, provide an installer.
[07:50:31] <ramdam> haha, wow
[07:50:36] <ramdam> kinda sucky
[07:50:38] <ramdam> i don't mind
[07:50:46] <pr3d4t0r> ramdam: Yeah, but it comes with the territory.
[07:50:47] <ramdam> it's just. i don't want others to bother
[07:51:05] <ramdam> i guess so
[07:51:18] <pr3d4t0r> ramdam: Whatever you're doing requires that library and path; thus, you need to do something about it.
[07:51:21] <illbeatu> what's the difference between a import javax.jms.Queue and a java.util.queue?
[07:51:24] <pr3d4t0r> ramdam: Look at the Tanuki wrapper.
[07:51:33] <pr3d4t0r> ramdam: That *may* help a bit.
[07:51:33] <ramdam> ~tanuki
[07:51:33] <javabot> ramdam, I have no idea what tanuki is.
[07:51:41] <Fanook> illbeatu: did you read the docs for both of those classes?
[07:51:45] <ramdam> ~wrapper
[07:51:45] <javabot> Each of Java's primitive types has a corresponding reference type called a wrapper. See http://java.sun.com/docs/books/tutorial/java/data/numberclasses.html for more information.
[07:51:51] <ramdam> nope
[07:51:53] <ramdam> that's not it
[07:51:55] <ramdam> google time
[07:52:02] <illbeatu> javax.jms.Queue is confusing. due to the jms part
[07:52:11] <illbeatu> java.util.queue is.. a queue heh
[07:52:13] <pr3d4t0r> ramdam: We're running a couple of things in production that use Tanuki.  It takes care of building a sensible path and run-time environment to satisfy dependencies.
[07:52:15] <Fanook> ~JMS
[07:52:15] <javabot> Fanook, JMS is Java Message Service and is found at http://java.sun.com/products/jms/ See also the JMS section in the J2EE tutorial at http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JMS.html There are various implementations including the horribly slow J2EE reference implementation, several free ones and poverty-inducing commercial ones
[07:52:35] <ramdam> pr3d4t0r, i see what you mean, it's kinda what i'm looking for
[07:52:40] <Fanook> presumably, the JMS one is optimized for the messaging service, the util one is optimized for general use
[07:52:49] <pr3d4t0r> ramdam: Tanuki may be all you need.  I don't recall if it's open-source or commercial.
[07:53:01] <ramdam> pr3d4t0r, but this assignment is due in 10 hours and i thought i could wrap it up nice and tidy
[07:53:02] <pr3d4t0r> ramdam: If in doubt, provide a .sh wrapper yourself.
[07:53:14] <pr3d4t0r> ramdam: bash is your friend :)
[07:53:37] <pr3d4t0r> ramdam: In fact, it might be better than Tanuki.  The latter has a learning curve, and you need to learn how to configure it.
[07:53:46] <pr3d4t0r> ramdam: bash is... bash :)  Easy to script.
[07:53:48] <ramdam> pr3d4t0r, hmm, let me entertain this bash idea
[07:53:52] <pr3d4t0r> ramdam: Cheers.
[07:53:57] <ramdam> but
[07:54:08] <ramdam> pr3d4t0r, the sh script won't wrapp
[07:54:13] <pr3d4t0r> Man, I feel soooooooooooooo not motivated to work on this other thing.  Maybe it's time to bed, then get up super-early to take care of business.
[07:54:22] <pr3d4t0r> ramdam: Won't wrapp...?
[07:54:23] <ramdam> pr3d4t0r, but atleast i can set the class path from the sh script
[07:54:43] <ramdam> pr3d4t0r, an sh script can contain files inside it?
[07:54:49] <pr3d4t0r> ramdam: Ah, gotcha.
[07:54:49] *** ttmrichter has quit IRC
[07:54:51] <pr3d4t0r> ramdam: No.
[07:54:56] <pr3d4t0r> ramdam: But your .jar can.
[07:55:09] <pr3d4t0r> ramdam: And the target system is likely to have both jar and/or unzip
[07:55:17] <pr3d4t0r> ramdam: See where I'm going with this?
[07:55:19] <ramdam> pr3d4t0r, then the sh script would have to unpack it for me and then set the cp to my .so
[07:55:26] <pr3d4t0r> ramdam: Yup.
[07:55:31] <pr3d4t0r> ramdam: Installer.
[07:55:33] <ramdam> pr3d4t0r, i see what you did there
[07:55:41] <ramdam> pr3d4t0r, nice, thanks man
[07:55:41] <pr3d4t0r> ramdam: However...
[07:55:46] <ramdam> pr3d4t0r,  ?
[07:56:06] <Fanook> or have your app unpack the libs before you try to use them, though you'll probably run into timing issues if you're not careful
[07:57:00] <pr3d4t0r> ramdam: You can also add some logic in there like:  if [[ ! -e /path/to/file.so ]]; then cp file.so /path/to; fi

[11:05:16] <Rounin> Ah no, here's the thing, W_work... The method I want to call isn't static
[11:05:21] <ramdam> giupo, yeah, but i don't know where those are defined :p
[11:05:27] <Rounin> I could make it static, but it's for an assignment
[11:05:34] <Rounin> So I might fail if I did
[11:05:51] <Rounin> So the method is in an object which contains this other object
[11:06:25] <Rounin> I could actually just pass it the containing object of course, but it uses generics in a way which I don't really understand yet, so I was hoping to avoid it somehow
[11:06:32] <giupo> ramdam: add a shell startup script where you redefine them. (Bash case) cat "export PATH=$PATH:<youraddedpathhere>" >> $HOME/.bashrc
[11:06:56] <giupo> I would rather not mess with filesystem under /usr ;)
[11:06:56] <W_work> Rounin, what I gave you was for a non-static method
[11:06:58] <ramdam> yeah, i'm planning on doing an installer
[11:07:13] <ramdam> giupo, but i don't have time right now, i gotta crank this code faster than taht
[11:07:22] <W_work> Rounin, the "this" is a big hint...
[11:07:28] <ramdam> giupo,  the installer is the like the last thing to do.
[11:07:56] <giupo> ramdam: no objections as far is your system ;)
[11:08:29] <ramdam> giupo,  i don't get what the big fuss is about, it's my lib, i don't see the problem, it's not like i changed files down there

[11:09:35] <Rounin> Oh... Well, hm, it says that the containing class isn't a containing class, so I guess I'd better just pass it the object when I find out how

[11:44:32] <mapreduce> Hi.  I'm benchmarking java.awt.Toolkit versus FFmpeg for decoding JPEGs into java.awt.Images, and on another axis an input type of ByteBuffer versus byte[].
[11:44:33] <midbit> is it possible to change the background of an image ( dynamic ) using java imageIO ?

[12:04:01] <mapreduce> And a direct one at that.

[13:25:58] <slonkko> Fanook: here is  is modified code and error on bottom of pastebin, could you help a bit
[13:26:26] <W_work> slonkko, that error message is pretty clear
[13:26:30] <W_work> ~~slonkko access modifiers
[13:26:31] <javabot> slonkko, access level is one of 'public' ,'private', 'protected', or default a.k.a. package private. They control which code is allowed to access the attribute / call the method. public means: Everybody, 'private' means: Only stuff in this source file.  For more info, see ~public, ~private, ~package-private, and ~protected, and this link: http://is.gd/eJYt (sun.com)
[13:26:55] <slonkko> W_work:  so if i give it public then it will work?
[13:27:07] <roots_> yura: that works since 1.1
[13:27:10] <roots_> but its stupid
[13:27:11] <W_work> slonkko, no
[13:27:14] *** igordcard has joined ##java
[13:27:23] <roots_> and its an anonymous class with an init block
[13:27:23] <W_work> slonkko, the whole method is wrong and bad, but adding public will remove the compiler error
[13:27:30] <roots_> so its stupid since a long time
[13:28:06] <slonkko> W_work: could you explain how to fix it, im new at java, and programming in python,c,oracle pl/sql etc for years..
[13:28:13] <slonkko> W_work: so i guess i'll understand it
[13:28:30] <slonkko> W_work: atleast i hope so :)

[13:39:37] <jonaslund> slonkko: they added stuff to the jdbc interface in 1.6.. your implementation seems quite bare so just adding the new methods should work.
[13:40:02] <jonaslund> slonkko: however i know that the tomcat ones _should_ close outstanding statements, resultsets,etc as long as you close the connection itself
[13:40:32] <slonkko> jonaslund:  tnx, i managed to add createStruct and it kinda works... (with cast)
[13:40:32] <jonaslund> (not that you really should do less bookkeeping just because it helps out :)
[13:41:13] <slonkko> jonaslund:  now im at createarray and it looks kinda weird to do so much casting..  should this work ?

[15:20:27] <cheeser> you could loop...

[15:20:32] *** UT2K3 has joined ##java
[15:20:35] <Absolute0> I was thinking of putting the static list into a hash with just key = null, and iterating over the second list

[15:21:08] *** shadewind has joined ##java
[15:21:24] <Absolute0> retrieving values is constant time and iterating over the dynamic list is linear

[15:40:10] <dvayanu> i want to have a map where Class<XYZ>, is used as key and instance of XYZ as object

[15:40:44] <dvayanu> multiple
[15:40:57] <W_work> then you can't use a generic variable, you have to use a wildcard
[15:41:14] *** shadewind has quit IRC
[15:41:16] <dvayanu> yes, but with wildcards i can't add generics to the methods too
[15:41:24] <W_work> you can encapsulate /access/ to this map of course, to enforce that a class doesn't map to an instance of a different type
[15:41:28] <dvayanu> this is the method , which uses the map: public static <T> T get(Class<T> pattern)
[15:41:31] <W_work> sure you can
[15:41:50] <W_work> I don't see the problem
[15:41:58] <W_work> Class<T> matches the Class<?> wildcard
[15:42:09] <dvayanu> nope
[15:42:22] <W_work> oh wait, of course it doesn't
[15:42:36] <dvayanu> instances.put(pattern, instance); -> The method put(Class<?>, capture#3-of ?) in the type Map<Class<?>,capture#3-of ?> is not applicable for the arguments (Class<T>, T)
[15:42:41] <W_work> you have to do Map<Class,Object>

[15:43:10] <W_work> indeed
[15:43:11] <W_work> so do that
[15:43:16] <dvayanu> but i wanted to force it use generics :-)
[15:43:20] <W_work> you can still encapsulate access, as I said
[15:43:22] <W_work> why?

[15:45:12] <dvayanu> cause compiler doesn't warn you if you change the method but not the comment
[15:45:13] <W_work> the relationship is between map ENTRIES, not between the type of the key and values of the map
[15:45:44] <dvayanu> the relationship is that key is the object class of the object
[15:45:56] <dvayanu> Map.class, new HashMap
[15:46:00] <W_work> yes, which only holds for specific entries inside the map
[15:46:10] <dvayanu> but not List.class, new HashMap
[15:46:25] <W_work> there's no feature in Java to describe such constraints (except classes themselves)
[15:46:27] <dvayanu> which means that this constraint is to be ensured by code, not by compiler
[15:46:36] <dvayanu> yeah, i know now :-)
[15:46:49] <dvayanu> i thought there would be something, which i don't know, so i asked
[15:47:25] <W_work> you could create your own ClassEntry<Class<T>,T> for instance, but you would still have Set<ClassEntry<?>>
[15:47:56] <dvayanu> or don't use generics internally, only in the public methods of the class
[15:48:11] <dvayanu> which is still enough to provide compile time security for the user of the class
[15:48:13] <W_work> yeah, you're going to encapsulate anyway

[15:54:32] <W_work> I typically avoid having such registries, and just pass Factory<T> or similar to whatever method needs it
[15:54:44] <goki-_-> dvayanu: Do you want to know that when you retrieve a Factory from the map, it will be for the type of class that you looked it up with?
[15:55:16] *** teralaser has quit IRC
[15:55:28] <goki-_-> That is, map.get(String.class) should return a Factory<String> ?
[15:55:45] <dvayanu> w_work: i actually could create a "Service" interface and it will work fine, but i didn't want to restrict it to usage of my interfaces
[15:55:52] <dvayanu> goki-_- yes
[15:56:17] <goki-_-> dvayanu: you can do it, but it isn't a Map<"X"> for any "X" you can come up with
[15:56:26] <goki-_-> you need a parametric method in your own interface
[15:56:39] <W_work> goki-_-, he's already done that
[15:56:45] <goki-_-> public <T> Factory<T> getFactory(Class<T> class)
[15:56:47] <dvayanu> goki-_- we've actually been through it,
[15:56:49] <goki-_-> oh ok, sorry ;)
[15:57:01] <dvayanu> nevermind :-)
[15:57:33] <goki-_-> was there a problem with that approach? I use it myself for something else. It requires suppressing a warning, but logically the warning is not valid as long as the code is properly written.

[16:33:12] *** Malformation has quit IRC
[16:33:15] <odinsbane> It was just an idea for a simulation, we have 10,000 points that might move.
[16:33:35] <odinsbane> The question was should we move the points before all of the other points have updated or after.
[16:34:02] <eidolon> so your answer is to give every point it's own thread?
[16:34:06] <Apocalisp> Or... all at the same time, right?
[16:34:08] <eidolon> instead of, you know, perhaps using a map?
[16:34:34] <odinsbane> I don't know about using a map.
[16:34:37] <eidolon> nothing says good programming like increasing the overhead several orders of magnitude per data point.
[16:34:43] <Apocalisp> What kind of data structure stores the points?
[16:34:58] *** kank has joined ##java
[16:35:30] <odinsbane> right now there are two double[] arrrays that store the x/y, I want to change it to an object with x,y members.
[16:35:30] *** igordcard has quit IRC
[16:36:07] <Apocalisp> OK, what will store all those objects?
[16:37:31] <odinsbane> Possibly an array, though that is something we are considering.
[16:38:44] <Apocalisp> What makes the points move?
[16:39:33] *** riotz has joined ##java
[16:39:44] <odinsbane> a function iterates over all of the other points, and usings if/then/else for criteria.
[16:40:09] <odinsbane> That function also moves the points, changes their x/y values.
[16:40:23] <Apocalisp> OK, so the position of point p at time t+1 is a function of all other points at t.
[16:40:41] <Apocalisp> Sounds like a job for parFlatMap
[16:41:12] <eidolon> i'd probably dupe the map into a new instance during processing.

[16:42:08] <odinsbane> Ill look up the parflatmap.
[16:42:30] *** ImmortalFire has quit IRC
[16:42:50] *** twolf has joined ##java
[16:43:23] <eidolon> short answer.  don't make threads.  :)

[16:45:28] *** gyroscope has quit IRC
[16:46:01] <cheeser> um.  what?
[16:46:46] <Apocalisp> Do we need to say it in all caps?
[16:47:12] <cheeser> why never call new Thread?
[16:47:36] <Apocalisp> Because java.util.concurrent already does that for you.
[16:47:51] <cheeser> well, that's a different answer though.
[16:48:02] <cheeser> calling new Thread is perfectly acceptable in many cases.
[16:48:20] *** tom17bombadil has quit IRC
[16:48:40] <Apocalisp> Yes, like when you're implementing a threading strategy, or a very simple toy program.

[16:51:23] <cheeser> for javadocs
[16:52:10] <pertl> I was more interested in something coming from the holy apple itself... they deliver that stuff for java 5 already, just java 6 seems to be missing

[17:34:14] *** [dot]Al has quit IRC
[17:34:26] <thecarlhall> HexKey: .close() is defined in Object.  Just casting it should be fine as ArrayList overrides .clone()
[17:35:00] <thecarlhall> HexKey: one thing there though.  The JavaDoc for ArrayList says .clone() is only a shallow copy and doesn't copy the elements.
[17:35:12] <raf64flo> Is it possible to map tables from database into java objects without using a DAO layer ? I mean i.e. a XML file mapping database's tables's attributes to objects not corresponding exactly to the table but being object directly used by the application for traitments ?
[17:35:14] <cheeser> it doesn't *clone* the elements.
[17:35:21] <cheeser> but it copies over references to the new List
[17:35:48] <thecarlhall> Will .addAll(..) copy the elements?
[17:35:52] <cheeser> raf64flo: a DAO is just an abstraction/layer in which to place logic to interact with your datastore
[17:36:01] <HexKey> it worked :D
[17:36:02] <cheeser> thecarlhall: it will copy the references

[17:59:22] <killerbun> Im trying to use jUnit to test threads. My setup is: Insert into database, run thread, sleep, test, delete from database. The problem is that when i sleep another tests starts and the database gets screwed.
[17:59:31] <pertl> use SimpleDateFormat
[17:59:42] <killerbun> Does anyone know a good solution to this, i want to keep jUnit vanila.
[18:00:02] <[pwgr]> use testng
[18:00:09] <MacFlecknoe_> why dont you clean up your changes before the next iteration of tests?
[18:00:09] <pertl> don't fall asleep
[18:00:39] <killerbun> MacFlecknoe_, thats what i do, but the next test starts before the last completed.
[18:01:13] <pertl> use thread synchronization
[18:01:17] <MacFlecknoe_> then the problem isnt avoidable... you cant do that... its a race condition
[18:02:00] <`Deimos`> hi all
[18:02:39] <killerbun> MacFlecknoe_, i was hoping that jUnit could be setup to handle this or maybe thread sync will work
[18:03:48] <MacFlecknoe_> asetup to handle what exactly? you are running two independant tests in a single database with an inherent race condition in the setup... you need to either clean up between calls or run the tests on different copies of the database
[18:03:51] *** Resistance has quit IRC
[18:04:09] *** Resistance has joined ##java
[18:04:12] <killerbun> MacFlecknoe_, im cleaning up between calls.
[18:04:35] <killerbun> But i want jUnit to not startup another thread with another test when i use Thread.sleep
[18:04:53] <MacFlecknoe_> why are you running them as threads then
[18:05:08] <killerbun> Because what im testing is a thread.
[18:05:28] <killerbun> The race isnt within the test, its between tests.
[18:05:46] <pertl> killerbun: you can't get away without some means of thread synchronization
[18:06:29] <pertl> the whole purpose of threads is to run in parallel so you need some sync to make them wait for each other
[18:07:43] <killerbun> Lets try it again.... jUnit is starting up another thread without asking me, when i use Thread.sleep within a testcase, can i stop it from doing that ?
[18:08:36] <marvi> It is the next test that starts and creates a new thread?
[18:08:47] <killerbun> Yes
[18:09:07] <killerbun> So i have to tests going at the same time, because i call Thread.sleep within one of the tests.
[18:09:14] <killerbun> This screws up my database.
[18:09:19] <killerbun> two even.
[18:09:33] <marvi> Well, that is how threads work.
[18:10:08] *** Thieh has left ##java
[18:10:36] <pertl> use java.util.concurrent.locks.Lock to synchronize access to your database
[18:10:54] <marvi> Your test will finish since it's finished. The next test will start. You need to use some kind of lock.
[18:11:50] *** Yustme has joined ##java
[18:12:04] <pertl> killerbun: java.util.concurrent.locks.ReentrantLock will just work fine

[18:12:17] *** NiSoOo has quit IRC
[18:12:30] <roots_> jdbc itself is just silent on the issue
[18:13:20] <roots_> in any case you will not be able to screw your database, maybe your client will freeze
[18:13:23] *** alek_b has quit IRC
[18:13:32] <marvi> I think it is better to make the test clean up after itself. If it starts threads it should make sure they are ended before finishing execution. Unit tests should be isolated.
[18:13:56] <killerbun> marvi, this is what im trying to do
[18:14:00] *** durka42 has quit IRC
[18:14:19] <killerbun> so im basicly doing thread.start(), thread.sleep(1000), thread.interupt()
[18:14:19] <pertl> killerbun: so why not simply use a lock?
[18:14:48] <killerbun> pertl, i might look into that, its diffently worth a try.
[18:14:58] <MacFlecknoe_> its the only thing you can do
[18:15:06] <pertl> yep
[18:15:36] *** javver has quit IRC
[18:15:42] <killerbun> Or use the magical "dont start more threads, when i sleep" option i junit :)

[18:21:52] <marvi> blahjake: the Geronimo project has packaged open sourced versions of all the Java EE API:s.
[18:22:25] <cheeser> all the JEE apis are open source from sun

[18:22:53] *** b3nn3tt has joined ##java
[18:23:26] <marvi> cheeser: a lot of them are not available. JTA as an example.
[18:23:28] <marvi> http://mirrors.ibiblio.org/pub/mirrors/maven2/geronimo-spec/

[18:32:23] <Segaja> hi, how can i add something like an on mouseover textbox to a jpanel?
[18:32:41] *** bas-i has quit IRC
[18:32:56] <wolfeySI> textbox? or you mean just set tooltip?
[18:33:06] *** marvi has left ##java
[18:33:09] <Segaja> tooltip would be enough
[18:33:25] <Segaja> the mouse listener is the easy part
[18:33:27] <wyvern`> so, does anyone have a preferred JMS provider? Interop with PHP (e.g. like ActiveMQ's Stomp implementation) is necessary
[18:33:40] <Segaja> but i don't know how to add the tooltip
[18:33:57] <wolfeySI> http://java.sun.com/javase/6/docs/api/javax/swing/JComponent.html#setToolTipText(java.lang.String)
[18:34:02] <MacFlecknoe_> i have a question... what is more elegant in a junit test: 1. to test ouput of a method using an assert adn then use another assert to test its value or 2. to simply allow a null pointer to be thrown from the latter assertion?
[18:34:26] <Segaja> thanks wolfeySI, i will have a look at it
[18:34:39] <wyvern`> MacFlecknoe_, I'd say neither. You should explicitly test for null when you expect null.
[18:34:40] <MacFlecknoe_> rather... 1. to test the output of a method for null using assertNotNull
[18:34:42] <wyvern`> and vice versa
[18:35:04] <wyvern`> you should always know based on which specific test method whether or not you expect null.
[18:35:21] <MacFlecknoe_> wyvern`:  that is what i am doing now... it just seems redundant
[18:35:33] <MacFlecknoe_> as a null pointer will result in a failure
[18:35:43] <wyvern`> oh, i think i see what you're doing
[18:35:51] <wyvern`> are you doing assertNotNull then an assertEquals?
[18:35:55] <MacFlecknoe_> yeah
[18:36:03] <wyvern`> you don't need the not null; the assertequals will do that.
[18:36:05] *** bas-i has joined ##java
[18:36:18] *** [dot]Al has left ##java
[18:36:21] <MacFlecknoe_> yeah i know... i just wanted to know if that was best practice....
[18:36:32] <MacFlecknoe_> ill change them i think...
[18:36:48] <Segaja> wyvern`: i have one big box with text in it and i want to add to several words different tool tips
[18:37:03] <wyvern`> Segaja, sorry, i don't know swing
[18:37:03] <Segaja> do i need to encapsulate these words in specific elements?
[18:37:46] *** cyzie has joined ##java
[18:38:04] <magmarules> Can anyone recomend me a xslt java lib ?
[18:39:50] <Segaja> or how else can i get the correct position for the tooltip
[18:39:52] <Segaja> ?
[18:42:33] <wolfeySI> tooltip is always relative to mouse position i think
[18:42:36] <wolfeySI> over component
[18:42:40] <wolfeySI> not exactly your job to do
[18:42:50] <wolfeySI> you just set tool tip for that component

[20:08:44] <icefyre> can someone tell me how to limit Doubles to two decimal places in my output?
[20:09:25] <icefyre> I've tried using String.format with the following format string "%.3g"
[20:09:57] <ernimril> icefyre: try "%.2f"
[20:10:01] <icefyre> but it is doing it to three sig figs
[20:10:13] <icefyre> k just a sec
[20:10:24] <ernimril> icefyre: what do you think the _3_ is for in your pattern?
[20:10:46] <icefyre> when I did it with 2, it gave me to 2 sig figs
[20:10:50] <icefyre> so it would be like 3.1
[20:10:58] <icefyre> when I needed 3.10
[20:11:05] <icefyre> I think %.2f works

[20:19:35] *** Daniel_H has joined ##java
[20:20:02] <odinsbane> Can threading help with dual core processors?  Or is it the same as similar to using a single processor
[20:20:34] <illbeatu> odinsbane, my best guess would be that it is similar to single core processor nowdays.
[20:20:38] *** icefyre has left ##java
[20:20:41] <ernimril> odinsbane: if you have multiple cores and run several threads at the same time you will use more cores
[20:21:19] <illbeatu> ernimril, i think he's wondering if processor makers have managed to hide the fact that there are multiple cores from developers
[20:21:40] <illbeatu> as in, the api exists to program multiple cores transparently
[20:22:57] *** teralaser has joined ##java
[20:25:14] <odinsbane> I like ernimril's answer, though it does seem to have a hidden caveat.  As in Ill be using more cores, but not nescessarily speeding up my program.
[20:25:37] <repnop> if you do it correctly you will gain performance.
[20:25:54] <ernimril> but doing correct and efficient multi threading is very hard
[20:25:56] *** hanen has joined ##java
[20:26:08] <repnop> ernimril: of course it depends on the requirements of the software. :)
[20:26:28] <repnop> some things are trivially easy to scale, others are difficult to scale even to 2 threads.
[20:27:21] <odinsbane> I think mine is almost a simple case.
[20:28:26] <ernimril> repnop: if you find multi threading easy, then I am happy for you. I use multi threading and have been doing it for several years, but I still get to debug race conditions and similar. Sure there are a few cases where it may not be that hard to get it correct, but if you need to pass messages between threads it gets hard very fast

[20:30:30] <vinse> that's a line from the oracle docs
[20:30:58] <vinse> what do they mean by "j2ee standard orion-web.xml file"? are they saying that's not an oracle-specific file?

[20:51:55] <Andrew`_> How would you reccomend building a GUI in java? Hand coding it or using a builder?
[20:52:07] <cheeser> svm_invictvs: which guys?
[20:52:15] <Andrew`_> It will be more complicated than a simple text box and a few buttons
[20:52:17] <cheeser> Andrew`_: by hand typically
[20:52:24] <Andrew`_> is that the standard?
[20:52:28] <ernimril> Andrew`_: yes
[20:52:29] <cheeser> look at miglayout to alleviate some of the apin.
[20:52:41] <Andrew`_> ok cool, thankyou :)
[20:52:43] <ernimril> Andrew`_: hand coding gives you code that is readable and maintainable
[20:53:00] <Andrew`_> yeah that's what i thought, some doc on java.com made me think most people used builders but i don't like them
[20:53:01] <ernimril> Andrew`_: that means that anyone on the team can tweak the layout later on
[20:53:21] <Andrew`_> cool, thanks guys!

[21:36:35] <kbss> anyone aware of a way to graph java source code dapendencies? (not class files)
[21:37:11] <carranca> cheeser, well, from what Ive seen Jboss seems like a "tomcat" without using the apache webserver... Ive worked with apache, i like apache :P
[21:37:26] <Sou|cutter> kbss: what do you mean not class files?
[21:37:39] *** BeholdMyGlory has joined ##java
[21:37:44] <Sou|cutter> carranca: tomcat doesn't use the apache webserver
[21:37:59] <carranca> jonasbjork, well, i like the sentence "and a refreshing lack of XML,"
[21:38:05] <Sou|cutter> although you can use it with apache webserver if you want
[21:38:14] <cheeser> carranca: the jboss app server includes an httpd, yes.
[21:38:15] <kbss> sou: For example JDepend can extract dependency graph but only from class files. I need a tool to extract it from source files without the need to compile them
[21:38:17] <cheeser> probably based on tomcat.
[21:38:23] *** whaley has joined ##java
[21:38:39] <cheeser> kbss: you could jsut compile them and then scan them...
[21:38:52] <Sou|cutter> why do you need to not compile them?
[21:39:02] <carranca> cheeser, my mistake then, I thought tomcat was on top of apache
[21:39:28] <drichards> tomcat rocks.
[21:39:34] <cheeser> if by apache you mean apache httpd, no.
[21:39:45] <cheeser> tomcat *is* and ASF (or apache) project, though.
[21:39:53] <kbss> Cheeser: im trying to avoid that .. because i need to create a graph animation of how the source code evolves in a repository ... imagine having to need to compile after every commit!
[21:40:12] <cheeser> kbss: ah.  now that makes sense.

[21:41:34] <kbss> im am surprized that there is no tool to generate dependency graph exists for java ... there are some available for C, python, perl
[21:41:45] <Sou|cutter> kbss: so first time will take forever, but keeping it updated would be less intense

[22:24:36] <svm_invictvs> rgravener: Use pandora--'s glassbox framework.  It's got a serializer in it.  If that's not appropriate, then you'll have to implement a byte array output stream yourself.
[22:24:47] <svm_invictvs> rgravener: I have my own serializer lib fro my game that I wrote.

[22:29:19] <svm_invictvs> Means, you don't *have* to use sqlite you *choose* to use it.
[22:29:43] <jonaslund> the biggest fault with recordstores is that you really can't do random-access inside the records

[22:47:23] <Sou|cutter> you can't really force a gc

[22:49:58] *** emma has quit IRC
[22:50:01] <dmlloyd> I'd expect a weakref to hang around as long as possible.  If you want a ref to hang around until memory is kinda tight, consider a softref

[23:00:51] <uttumuttu> not sure if this helps anything (i have a two-core processor, though)
[23:01:34] <jonaslund> uttumuttu: if you don't have any connection pooling happening elsewhere then if all operations are within the same thread and complete then just put a "finally" somewhere in the callstack that closes it
[23:01:40] <cheeser> Keal: http://is.gd/ixyt

[23:03:56] <Keal> is there an 8.1?
[23:03:59] <cheeser> no
[23:04:07] <cheeser> 1.6 is the latest.
[23:04:10] <Wicked> hmm...on profiling memory usage....im trying to do that on my program at the moment...but im not sure how to further figure out what is using the memory. In the netbeans profiler the top 2 biggest memory usages its showing are: char[] and java.lang.Object[] .....is there any way to further find out whats the cause?.
[23:04:17] <cheeser> 1.6 update 12 to be exact
[23:04:34] <juanez> Wicked: eclipse has a *very* useful memory profiler tool
[23:04:38] <Keal> then somehow at one point i must have come across a bogus 1.8 then reformatted and reinstalled using 1.6

[23:06:26] <Wicked> it actually told me what methods where causing the high cpu usage..but the memory profiler doesnt seem to do the same.
[23:06:34] <Keal> cheeser if i have 1.8 do i already have JRE 1.1 installed? or do i need to download and install both that and JDK 1.1 ?
[23:06:42] <cheeser> Keal: there is no 1.8
[23:06:48] <Keal> i meant 1.6
[23:06:53] <cheeser> 1.1 is over a decade old

[23:13:53] <Wicked> yea. theme for ubuntu.
[23:14:01] <juanez> oh... ouch :S
[23:14:03] <dmlloyd> hoonteke: I'm assuming that hexColor is an int that is already known to be between 0x000 and 0xfff.

[23:14:40] <Keal> cheeser does it mean the 32bit architecture with windows in general

[23:15:02] <Keal> ok thank you cheeser
[23:15:05] <u_quark> ok
[23:15:08] <juanez> Wicked: oh, no need for that ;)
[23:15:44] <dmlloyd> hoonteke: you'll have to deal with that in parsing, because #000123 is a valid color but different from #123.  I'd take the string, strip off the #, and use the string length.  If it's 3, then use Integer.parseInt(x, 16) to get the value and then run the formula I gave; otherwise use the result of parseInt() directly
[23:15:54] <u_quark> Sou|cutter: tnx

[23:49:13] <svm_invictvs> cheeser: The socket thing was about a guy who once was just going on and on about how it's impossible for an ejb to open a serversocket.
[23:49:25] <cheeser> bean != ejb
[23:49:52] *** bas-i has quit IRC
[23:50:00] <svm_invictvs> cheeser: yeah, I know.
[23:50:19] <svm_invictvs> I have one those headaches where it feels like your eye is gonna explode in your forehead.  Give me a break.
[23:51:07] <ahughes> svm_invictvs, you have been given a break. Go home.. put your feet up and relax.
[23:51:07] *** kevinvw has joined ##java
[23:51:11] <ahughes> :)
[23:51:30] <Seldon75> your headache makes you feel like cheeser's eye is gonna explode in his forehead?
[23:51:34] *** GunZ has quit IRC
[23:51:53] <Seldon75> crazy
[23:52:07] <Keal> cheeser: whatever happened to the 'coolbeans' line of products for java that sun microsystems came out with over 10 years ago?
[23:52:09] <svm_invictvs> heh
[23:52:15] <svm_invictvs> Seldon75: No.
[23:52:26] <svm_invictvs> Seldon75: And I didn't explicitly address cheeser
[23:52:35] <svm_invictvs> The royal "you" the editorial "you"
[23:52:55] <kevinvw> Hi, i'm trying to figure out what kind of datastructure i require for taking in a Resource object and returning a value from an enum. There is a Resource.toString() has the same name as the enum. Any ideas how i can do this?
[23:52:57] *** unbekannt has left ##java
[23:53:00] <Seldon75> i guess the term "one's" would have been the least ambiguous
[23:53:00] <ahughes> cheeser, I don't wanna convert html -> pdf. What I would like to do is have a broswer embedded in my swing app... then have some kind of bridge where I can manipulate the javascript state from inside java (possibly GWT).
[23:53:12] <svm_invictvs> Seldon75: ok
[23:53:21] <cheeser> flyingsaucer is an html renderer
[23:53:23] <svm_invictvs> There's a servlet in this assembly somewhere.
[23:53:47] <ojacobson> alcane: did you completely miss the part about ad-hoc classes?  Let me spell it out: the regular expression [abc] will match any of a, b, or c (once).
[23:53:52] <Seldon75> ahughes: you didnt completely read the factoid did you?
[23:54:09] <ahughes> cheeser, exactly.. not a browser... but thats for the heads up. It does look ok for other purposes
[23:54:15] <ojacobson> There is no \p and no {} here - those are specifically for named character classes, which are fixed and you can't create more.
[23:54:39] * ahughes rewinds...
[23:54:40] <Seldon75> apart from rendering HTML, writing a browser is trivial

[23:55:08] <Seldon75> you just grab the contents of an Http response
[23:55:55] <blahjake> ~~ kevinvw javadoc Enum.valueOf(Class,String)

[23:56:11] <svm_invictvs> Seldon75: and the security.
[23:56:24] <Seldon75> svm_invictvs: trivial with HttpClient
[23:56:32] <kevinvw> blahjake: i'll take a look at that, thank you
[23:57:28] <Keal> cheeser: thank you for all your help you provided.
[23:57:37] <cheeser> sure
