Class AsynchObserver

java.lang.Object
  com.deltax.util.listener.AsynchObserver

All Implemented Interfaces:

java.util.Observer

public class AsynchObserver

extends java.lang.Object

implements java.util.Observer

A wrapper class which allows to user a Listener in contexts where an Observer is required. Note that the synchoronous/asynchronous invocation will depend then on the specific Observer class, outside the boundaries of the framework.

Upon invocation of update() the class simply forwards the notification to the listener, passing an ObservableSignal containing both source (an Observable) and argument.
