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

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

Type Parameters:

EVENT -

Direct Known Subclasses:

ObjectReactOnce

public abstract class ObjectEventReactOnce<OBJECT extends IWorldObject,EVENT extends IWorldObjectEvent<OBJECT>>
extends ObjectEventReact<OBJECT,EVENT>

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 ObjectEventReact.react(IWorldObjectEvent) method automatically. The ObjectEventReact.react(IWorldObjectEvent) will be called only once (upon first event received).

If you need to react on every event, use ObjectEventReact.

Use ObjectEventReact.enable() and ObjectEventReact.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!
