Method Detail

wrap

public static OakEventFilter wrap(JackrabbitEventFilter baseFilter)

Wrap a JackrabbitEventFilter into its corresponding oak extension, OakEventFilter, on which some Oak specific observation filter extensions can then be used.

Parameters:

baseFilter - the base filter which contains other properties. Changes to the resulting oak filter "write-through" to the underlying baseFilter (for the features covered by the underlying) and similarly changes to the baseFilter are seen by the resulting oak filter. Note that this "write-through" behavior does no longer apply after a listener was registered, ie changing a filter after registration doesn't alter it for that listener.

Returns:

an OakEventFilter upon which Oak specific observation filtering extensions can be activated and then used when adding an EventListener with the ObservationManagerImpl.
