Method Summary

Modifier and Type	Method and Description
void	onDataTreeChanged(Collection<org.opendaylight.yangtools.yang.data.api.schema.tree.DataTreeCandidate> changes, Map<DOMDataTreeIdentifier,org.opendaylight.yangtools.yang.data.api.schema.NormalizedNode<?,?>> subtrees) Deprecated. Invoked whenever one or more registered subtrees change.
void	onDataTreeFailed(Collection<DOMDataTreeListeningException> causes) Deprecated. Invoked when a subtree listening failure occurs.

Method Detail

onDataTreeChanged

void onDataTreeChanged(@Nonnull
                       Collection<org.opendaylight.yangtools.yang.data.api.schema.tree.DataTreeCandidate> changes,
                       @Nonnull
                       Map<DOMDataTreeIdentifier,org.opendaylight.yangtools.yang.data.api.schema.NormalizedNode<?,?>> subtrees)

Deprecated.

Invoked whenever one or more registered subtrees change. The logical changes are reported, as well as the roll up of new state for all subscribed subtrees.

Parameters:

changes - The set of changes being reported. Each subscribed subtree may be present at most once.

subtrees - Per-subtree state as visible after the reported changes have been applied. This includes all the subtrees this listener is subscribed to, even those which have not changed.

onDataTreeFailed

void onDataTreeFailed(@Nonnull
                      Collection<DOMDataTreeListeningException> causes)

Deprecated.

Invoked when a subtree listening failure occurs. This can be triggered, for example, when a connection to external subtree source is broken. The listener will not receive any other callbacks, but its registration still needs to be closed to prevent resource leak.

Parameters:

causes - Collection of failure causes, may not be null or empty.
