Method Detail

addBeforeListener

public void addBeforeListener(org.opendaylight.mdsal.binding.api.DataTreeChangeListener<T> listener)

Description copied from interface: ChainableDataTreeChangeListener

Adds a "chained" DataTreeChangeListener, to which DataTreeChangeListener.onDataTreeChanged(java.util.Collection) calls are forwarded BEFORE having been processed by this DataTreeChangeListener.

If an asychronous DataTreeChangeListener supports chaining, it must forward the onDataTreeChanged() call BEFORE event are submitted to its async executor for processing.

Specified by:

addBeforeListener in interface ChainableDataTreeChangeListener<T extends org.opendaylight.yangtools.yang.binding.DataObject>

Parameters:

listener - the chained DataTreeChangeListener to invoke after this one

addAfterListener

public void addAfterListener(org.opendaylight.mdsal.binding.api.DataTreeChangeListener<T> listener)

Description copied from interface: ChainableDataTreeChangeListener

Adds a "chained" DataTreeChangeListener, to which DataTreeChangeListener.onDataTreeChanged(java.util.Collection) calls are forwarded AFTER having been processed by this DataTreeChangeListener.

If an asychronous DataTreeChangeListener supports chaining, it must forward the onDataTreeChanged() call ONLY AFTER its async executor processed the event.

Specified by:

addAfterListener in interface ChainableDataTreeChangeListener<T extends org.opendaylight.yangtools.yang.binding.DataObject>

Parameters:

listener - the chained DataTreeChangeListener to invoke after this one

notifyBeforeOnDataTreeChanged

public void notifyBeforeOnDataTreeChanged(Collection<org.opendaylight.mdsal.binding.api.DataTreeModification<T>> changes)

notifyAfterOnDataTreeChanged

public void notifyAfterOnDataTreeChanged(Collection<org.opendaylight.mdsal.binding.api.DataTreeModification<T>> changes)
