Interface FoTreeListener

All Superinterfaces:

java.util.EventListener

public interface FoTreeListener
extends java.util.EventListener

An interface for classes that need to handle FOTreeEvent objects as they are fired. The key benefit to using this interface is that the implementation can handle PageSequence objects at a higher level, rather than dealing directly with a lower-level SAX event.
