AbstractChangeable
Your implementation of this method should have the following structure:
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.
ChangeSupport cs = super.getChangeSupport(ct);
if(someForwarder == null && ct.isMatching(SomeInterface.SomeChangeType)) {
someForwarder = new ChangeForwarder(...
this.stateVariable.addChangeListener(someForwarder, VariableInterface.AChange);
}
return cs;
