Comment #1 on issue 103 by heue...@gmail.com: PInputEventFilter is Overly Complex
http://code.google.com/p/piccolo2d/issues/detail?id=103
I also dislike PInputEventFilter. Consider UnaryPredicate<K> and related from Apache Commons Functor http://commons.apache.org/sandbox/functor/apidocs/index.html and/or Predicate<T> and related from Google Collections/Guava http://guava-libraries.googlecode.com/svn/trunk/javadoc/index.html -- Piccolo2D Developers Group: http://groups.google.com/group/piccolo2d-dev?hl=en
