Interface FilteringAwareObserver

public interface FilteringAwareObserver

A FilteringAwareObserver is the stateless-variant of an Observer which gets an explicit before as well as the after NodeState.

It is used by the FilteringObserver (or more precisely by the FilteringDispatcher) to support skipping (ie filtering) of content changes.

Method Summary

Modifier and Type	Method and Description
void	contentChanged(NodeState before, NodeState after, CommitInfo info) Equivalent to the state-full contentChanged() method of the Observer with one important difference being that this variation explicitly passes the before NodeState (thus the observer must in this case not remember the previous state)
