There is a module producing data, and a module reading it for further processing. Moreover, in order to achieve better performance, usually there are many consumer modules running on many different threads while the producer (or several producers) run on its own thread.

In most cases, the function’s parameters can be set and the result retrieved using the common accessor pattern, such as setParameter1(Object value) or getResult(). The fact that these functions are encapsulated by real objects is also the reason for its greatest benefit: the use of [...]]]> http://chaoticjava.com/posts/functors-in-java-and-beyond/feed/ 6 http://chaoticjava.com/posts/know-your-streams/ http://chaoticjava.com/posts/know-your-streams/#comments Sat, 22 Dec 2007 08:21:59 +0000 Aviad http://chaoticjava.com/posts/know-your-streams/ dzone_url = "http://chaoticjava.com/posts/know-your-streams/";Isn’t it about time we got to know the different stream classes a bit better? We use them in almost every project, but what do they mean? How should can we use them more efficiently? And what is the difference between a Reader and an InputStream anyway?

For example, I wanted the code that analyses the elements and attributes of a complex element to work only on getter methods, that is, methods that begin with “get” or “is” and [...]]]> http://chaoticjava.com/posts/predicated-collections/feed/ 5 http://chaoticjava.com/posts/whirling-around-java/ http://chaoticjava.com/posts/whirling-around-java/#comments Tue, 07 Mar 2006 12:58:36 +0000 Aviad http://chaoticjava.com/posts/whirling-around-java/ dzone_url = "http://chaoticjava.com/posts/whirling-around-java/";About a month ago Roman Strobl mentioned the Whirl programming language on his blog, along with some other eccentric programming languages by the same author, Sean. Whirl is an odd programming language, reminding me a mutation of the accursed Enigma machine. It uses two wheel of 12 operation each, which the language’s operators rotate and [...]]]> http://chaoticjava.com/posts/whirling-around-java/feed/ 0 http://chaoticjava.com/posts/event-listener-registrations/ http://chaoticjava.com/posts/event-listener-registrations/#comments Mon, 13 Feb 2006 00:03:35 +0000 Aviad http://javachaos.crazyredpanda.com/?p=128 dzone_url = "http://chaoticjava.com/posts/event-listener-registrations/";Almost in any application, even the simplest one, we’ll encounter a use for events. Events follow the Observer-Observable design pattern. However, how should this be implemented? Clearly, the simplest solution is the following: public interface MyEventListener { void performMyEvent(MyClass sender); } public class MyClass { private Collection<MyEventListener> listeners; public void addMyEventListener(MyEventListener l) { listeners.add(l); } [...]]]> http://chaoticjava.com/posts/event-listener-registrations/feed/ 4 http://chaoticjava.com/posts/when-generics-gets-in-the-way/ http://chaoticjava.com/posts/when-generics-gets-in-the-way/#comments Sat, 11 Feb 2006 18:15:39 +0000 Aviad http://javachaos.crazyredpanda.com/?p=126 dzone_url = "http://chaoticjava.com/posts/when-generics-gets-in-the-way/";I’ve read Egypt Java Experts’ post about generics tips and even though I agree with the author’s claim that the generics feature make for a better API design, sometimes it’s just an overkill for the framework you’re designing.

Code just looks better, so it makes sense to switch these wrapper class to generified versions.

I can tell you that in just a few minutes I will open up IDEA and the X2J project and continue writing some code into it.
