Method Detail

getChangeSupport

public ChangeSupport getChangeSupport(ChangeType ct)

Description copied from class: AbstractChangeable

Called to retrieve the ChangeSupport for this object.

Your implementation of this method should have the following structure:

 ChangeSupport cs = super.getChangeSupport(ct);

 if(someForwarder == null && ct.isMatching(SomeInterface.SomeChangeType)) {
   someForwarder = new ChangeForwarder(...

   this.stateVariable.addChangeListener(someForwarder, VariableInterface.AChange);
 }

 return cs;
 

It is usual for the forwarding listeners (someForwarder in this example) to be transient and lazily instantiated. Be sure to register & unregister the forwarder in the code that does the ChangeEvent handling in setter methods.
