Interface CascadingEventFilter

All Superinterfaces:

AppendableEventFilter, EventFilter, Serializable

All Known Implementing Classes:

DefaultEventFilter

public interface CascadingEventFilter
extends AppendableEventFilter

A CascadingEventFilter is based on cascading filter sequences. An CascadingEventFilter can only hold one next EventFilter. When the next EventFilter is also a CascadingEventFilter, it can handle another EventFilter... That technique can be used to build filter sequences (cascading). A other solution to build filter sequences is available with CompositeEventFilter or rather EventFilterFactory.connect(EventFilter...).
