org.biojava.utils.ChangeForwarder
org.biojava.bio.Annotatable.AnnotationForwarder
- All Implemented Interfaces:
EventListener
,ChangeListener
- Enclosing interface:
Annotatable
Deprecated.
A helper class so that you don't have to worry about forwarding events from the Annotation object to the Annotatable one.
Once a listener is added to your Annotatable that is interested in ANNOTATION events, then instantiate one of these and add it as a listener to the annotation object. It will forward the events to your listeners and translate them accordingly.
This will ease the pain of letting your Annotatable tell its listeners about changes in the Annotation.- Author:

generateEvent
Deprecated.Description copied from class:ChangeForwarder
Return the new event to represent the originating event ce.
The returned ChangeEvent is the event that will be fired, and should be built from information in the original event. If it is null, then no event will be fired.
The default implementation just constructs a ChangeEvent of the same type that chains back to ce.
