public class EventPooler

extends Object

Posts events.

In order to be more efficient, the various events are pooled. The PainterThread.paint() method needs to modify these, and pass them to the queue. The pools are reused on a paintFinished event, created in the initialize() method, and cleaned up in the cleanup() method.

Note that the only non-pooled event is the FlushPaintingEvent. There is only one of these allocated.

Warning: this needs to be better documented.
