Examples with ClusterVersionListener com.hazelcast.internal.cluster.ClusterVersionListener used on opensource projects

Example 1 with ClusterVersionListener

use of com.hazelcast.internal.cluster.ClusterVersionListener in project hazelcast by hazelcast.

the class DefaultNodeExtension method registerListener.

@Override
public boolean registerListener(Object listener) {
    if (listener instanceof HazelcastInstanceAware) {
        ((HazelcastInstanceAware) listener).setHazelcastInstance(node.hazelcastInstance);
    }
    if (listener instanceof ClusterVersionListener) {
        ClusterVersionListener clusterVersionListener = (ClusterVersionListener) listener;
        clusterVersionListeners.add(clusterVersionListener);
        // on registration, invoke once the listening method so version is properly initialized on the listener
        clusterVersionListener.onClusterVersionChange(getClusterOrNodeVersion());
        return true;
    }
    return false;
}
