onDataTreeChanged

public void onDataTreeChanged(Collection<DataTreeModification<org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.network.topology.topology.Node>> changes)

Description copied from interface: DataTreeChangeListener

Invoked when there was data change for the supplied path, which was used to register this listener.

This method may be also invoked during registration of the listener if there is any pre-existing data in the conceptual data tree for supplied path. This initial event will contain all pre-existing data as created.

A data change event may be triggered spuriously, e.g. such that data before and after compare as equal. Implementations of this interface are expected to recover from such events. Event producers are expected to exert reasonable effort to suppress such events.

In other words, it is completely acceptable to observe a DataObjectModification, while the state observed before and after- data items compare as equal.

Specified by:

onDataTreeChanged in interface DataTreeChangeListener<org.opendaylight.yang.gen.v1.urn.tbd.params.xml.ns.yang.network.topology.rev131021.network.topology.topology.Node>
