public interface TagValueWrapper extends TagValueListener

Interface for TagValueListeners that wrap other TagValueListeners

Implementations will tend to intercept the tags or values as they stream through and modify them in some manner before forwarding them to the delegate listener. Using classes derived from SimpleTagValueWrapper, it is possible to build up complex chains of handlers that process and collate information as it streams through.
