Class ObjectEventReact<OBJECT extends IWorldObject,EVENT extends IWorldObjectEvent<OBJECT>>

java.lang.Object
  cz.cuni.amis.pogamut.base.communication.worldview.react.ObjectEventReact<OBJECT,EVENT>

Type Parameters:

EVENT -

Direct Known Subclasses:

ObjectEventReactOnce, ObjectReact

public abstract class ObjectEventReact<OBJECT extends IWorldObject,EVENT extends IWorldObjectEvent<OBJECT>>
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 IWorldObjectEvent for you and calls react(IWorldObjectEvent) method automatically.

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

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!
