Example 1 with ChildShardContext

use of org.opendaylight.mdsal.dom.spi.shard.ChildShardContext in project controller by opendaylight.

the class DistributedShardChangePublisher method setupListenerContext.

private <L extends DOMDataTreeChangeListener> AbstractDOMDataTreeChangeListenerRegistration<L> setupListenerContext(final YangInstanceIdentifier listenerPath, final L listener) {
    // we need to register the listener registration path based on the shards root
    // we have to strip the shard path from the listener path and then register
    YangInstanceIdentifier strippedIdentifier = listenerPath;
    if (!shardPath.isEmpty()) {
        strippedIdentifier = YangInstanceIdentifier.create(stripShardPath(shardPath, listenerPath));
    }
    final DOMDataTreeListenerWithSubshards subshardListener = new DOMDataTreeListenerWithSubshards(strippedIdentifier, listener);
    final AbstractDOMDataTreeChangeListenerRegistration<L> reg = setupContextWithoutSubshards(listenerPath, strippedIdentifier, subshardListener);
    for (final ChildShardContext maybeAffected : childShards.values()) {
        if (listenerPath.contains(maybeAffected.getPrefix().getRootIdentifier())) {
            // consumer has initialDataChangeEvent subshard somewhere on lower level
            // register to the notification manager with snapshot and forward child notifications to parent
            LOG.debug("Adding new subshard{{}} to listener at {}", maybeAffected.getPrefix(), listenerPath);
            subshardListener.addSubshard(maybeAffected);
        } else if (maybeAffected.getPrefix().getRootIdentifier().contains(listenerPath)) {
            // already registering to the lowest shard possible
            throw new UnsupportedOperationException("Listener should be registered directly " + "into initialDataChangeEvent subshard");
