public abstract class EventReact<EVENT extends IWorldEvent>
extends java.lang.Object

This abstract class allows you to easily hook a specific event-handling behavior. It automatically register a listener for a specified IWorldEvent for you and calls react(IWorldEvent) method automatically.

If you need to react only once to the event, use EventReactOnce.

Use enable() and disable() to enable react / disable react. The reaction is enabled as default.

WARNING:Use as anonymous class, but save it as a field of your class! Note, that we're using weak-references to listeners and if you do not save pointer to the object, it will be gc()ed!
