Java’s garbage collector has made life so easy for us developers that we sometimes confuse between deleting a reference, i.e. a task the GC does, and releasing a resource – a task the GC doesn’t do. That’s because the GC does something else for us called object finalization, [...]]]> http://chaoticjava.com/posts/simple-solution-to-resource-collection/feed/ 8 http://chaoticjava.com/posts/i-guess-priorityblockingdeque-wasnt-high-on-the-priority-list/ http://chaoticjava.com/posts/i-guess-priorityblockingdeque-wasnt-high-on-the-priority-list/#comments Fri, 14 Sep 2007 14:39:31 +0000 Aviad http://chaoticjava.com/posts/i-guess-priorityblockingdeque-wasnt-high-on-the-priority-list/ dzone_url = "http://chaoticjava.com/posts/i-guess-priorityblockingdeque-wasnt-high-on-the-priority-list/";A class I find missing in the new java.util.concurrent package is PriorityBlockingDeque. Just like PriorityBlockingQueue, this class should be sorting its elements either by their natural order or by a supplied Comparator. I fail to understand the reason for having this class obviously missing from the package, and because I need it very much, I [...]]]> http://chaoticjava.com/posts/i-guess-priorityblockingdeque-wasnt-high-on-the-priority-list/feed/ 19 http://chaoticjava.com/posts/retrieving-a-vms-pid-and-more-info-through-java/ http://chaoticjava.com/posts/retrieving-a-vms-pid-and-more-info-through-java/#comments Mon, 02 Jul 2007 20:20:06 +0000 Aviad http://chaoticjava.com/posts/retrieving-a-vms-pid-and-more-info-through-java/ dzone_url = "http://chaoticjava.com/posts/retrieving-a-vms-pid-and-more-info-through-java/";Ever wanted to be able to know your process’ PID through pure-Java, cross-platform methods? Or worse, other JVMs? At my work we came to a point where we needed to monitor and register a JVM’s PID (Linux/Windows/Whatever) for some future manipulation purposes. However, Java in itself did not contain the concept of “process ID” – [...]]]> http://chaoticjava.com/posts/retrieving-a-vms-pid-and-more-info-through-java/feed/ 5 http://chaoticjava.com/posts/generics-mess/ http://chaoticjava.com/posts/generics-mess/#comments Sun, 13 Aug 2006 02:13:22 +0000 Aviad http://chaoticjava.com/posts/generics-mess/ dzone_url = "http://chaoticjava.com/posts/generics-mess/";Sometimes, Generics can just cause a mess. Take for example the following definition I had to produce, just to get out of a Generified library I had somehow brought to life: public final class PlayerFinishedAction< TGame extends TurnBasedGame< ? extends Board, TPlayer, ? extends Turn<Phase<TPlayer>>, ? extends Phase<TPlayer>>, TPlayer extends TurnBasedPlayer> extends DefaultAction<TPlayer, Location> { [...]]]> http://chaoticjava.com/posts/generics-mess/feed/ 7 http://chaoticjava.com/posts/bi-directional-type-safe-containers/ http://chaoticjava.com/posts/bi-directional-type-safe-containers/#comments Mon, 31 Jul 2006 08:34:44 +0000 Aviad http://chaoticjava.com/posts/bi-directional-type-safe-containers/ dzone_url = "http://chaoticjava.com/posts/bi-directional-type-safe-containers/";It seems that in almost every system I write has a bi-directional containment. For example, a Table instance containing Column instances that should know to reference back to the Table instance containing them.

This feature seems to come as a complement to the major EoD feature in Tiger, Generics.

Heck, we can even iterate over all of them, eliminating the need of the old-fashioned C++ “START” and “END” values. Enums are much more though.

However, the current apt tool doesn’t really cut it. For example, it doesn’t seem to allow for processing inside code portions, only on declarations such as method declarations and class declarations. Another annoyance is with the way the apt API is supplied: The annotation processing [...]]]> http://chaoticjava.com/posts/annotation-processing-then-and-tomorrow/feed/ 1
