Example 6 with Modification

use of org.opendaylight.controller.cluster.datastore.modification.Modification in project controller by opendaylight.

the class EntityOwnershipShard method onVotingStateChangeComplete.

@Override
protected void onVotingStateChangeComplete() {
    // Re-evaluate ownership for all entities - if a member changed from voting to non-voting it should lose
    // ownership and vice versa it now is a candidate to become owner.
    final List<Modification> modifications = new ArrayList<>();
    searchForEntities((entityTypeNode, entityNode) -> {
        YangInstanceIdentifier entityPath = YangInstanceIdentifier.builder(ENTITY_TYPES_PATH).node(entityTypeNode.getIdentifier()).node(ENTITY_NODE_ID).node(entityNode.getIdentifier()).node(ENTITY_OWNER_NODE_ID).build();
