Examples with CRDTReplicationContainer com.hazelcast.internal.crdt.CRDTReplicationContainer used on opensource projects

Example 1 with CRDTReplicationContainer

use of com.hazelcast.internal.crdt.CRDTReplicationContainer in project hazelcast by hazelcast.

the class PNCounterService method prepareMigrationOperation.

@Override
public CRDTReplicationContainer prepareMigrationOperation(int maxConfiguredReplicaCount) {
    final HashMap<String, VectorClock> currentVectorClocks = new HashMap<>();
    final HashMap<String, PNCounterImpl> counters = new HashMap<>();
    final Config config = nodeEngine.getConfig();
    for (Entry<String, PNCounterImpl> counterEntry : this.counters.entrySet()) {
        final String counterName = counterEntry.getKey();
        final PNCounterImpl counter = counterEntry.getValue();
        if (config.findPNCounterConfig(counterName).getReplicaCount() >= maxConfiguredReplicaCount) {
            continue;
        }
        counters.put(counterName, counter);
        currentVectorClocks.put(counterName, counter.getCurrentVectorClock());
    }
    return counters.isEmpty() ? null : new CRDTReplicationContainer(new PNCounterReplicationOperation(counters), currentVectorClocks);
}
