Class RhiEventTarget

java.lang.Object
  Rhinohide
      RhiEventTarget

All Implemented Interfaces:

EventTarget

Direct Known Subclasses:

RhiNode, RhiWindow

@ThreadSafe
public class RhiEventTarget
extends Rhinohide
implements EventTarget

An event target implemented as an overlay of a JavaScript event target.

Note: If in-memory caching is in effect, listeners should probably be removed, during page exit. Caching will persist JavaScript-side listener registrations; but not (apparently) the Java-side listeners.
