Package org.apache.jackrabbit.oak.plugins.observation

Interface Summary

Interface	Description
EventHandler	Handler of content change events.
ExcludeExternal	The presence of this marker interface on a EventListener indicates that cluster external observation events must not be reported to that event listener.
Filter	A filter is used by the FilteringObserver to decide whether or not a content change should be forwarded.
FilteringAwareObserver	A FilteringAwareObserver is the stateless-variant of an Observer which gets an explicit before as well as the after NodeState.

Class Summary

Class	Description
ChangeCollectorProvider	A ChangeCollectorProvider can be hooked into Oak thus enabling the collection of ChangeSets of changed items of a commit, which downstream Observers can then use at their convenience.
CommitRateLimiter	This CommitHook can be used to block or delay commits for any length of time.
DefaultEventHandler	Default implementation of EventHandler that does nothing.
EventGenerator	Continuation-based content diff implementation that generates EventHandler callbacks by recursing down a content diff in a way that guarantees that only a finite number of callbacks will be made during a EventGenerator.generate() method call, regardless of how large or complex the content diff is.
FilteredHandler	Filtered event handler.
FilteringDispatcher	Part of the FilteringObserver: the FilteringDispatcher is used to implement the skipping (filtering) of content changes which the FilteringDispatcher flags as NOOP_CHANGE.
FilteringObserver	An observer that implements filtering of content changes while at the same time supporting (wrapping) a BackgroundObserver underneath.
NodeObserver	Base class for Observer instances that group changes by node instead of tracking them down to individual properties.
