Package org.apache.jackrabbit.oak.jcr.observation.filter

Class FilterFactory

  • public class FilterFactory
extends java.lang.Object
    Static factory that allows wrapping a JackrabbitEventFilter into an OakEventFilter that contains some oak specific extensions.

    The resulting filter can subsequently be used in ObservationManagerImpl.addEventListener as usual.

        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.
