Examples with NodeListener io.vertx.core.spi.cluster.NodeListener used on opensource projects

Example 1 with NodeListener

use of io.vertx.core.spi.cluster.NodeListener in project vert.x by eclipse.

the class HAManager method init.

/**
 * Initialize the ha manager, i.e register the node listener to propagates the node events and
 * start the quorum timer. The quorum will be checked as well.
 */
void init() {
    synchronized (haInfo) {
        clusterMap.put(nodeID, haInfo.encode());
    }
    clusterManager.nodeListener(new NodeListener() {

        @Override
        public void nodeAdded(String nodeID) {
            HAManager.this.nodeAdded(nodeID);
        }

        @Override
        public void nodeLeft(String leftNodeID) {
            HAManager.this.nodeLeft(leftNodeID);
        }
    });
    quorumTimerID = vertx.setPeriodic(QUORUM_CHECK_PERIOD, tid -> checkHADeployments());
    // Call check quorum to compute whether we have an initial quorum
    synchronized (this) {
        checkQuorum();
    }
}

Example 2 with NodeListener

use of io.vertx.core.spi.cluster.NodeListener in project vert.x by eclipse.

the class VertxStartFailureTest method testHAManagerInitFailure.

@Test
public void testHAManagerInitFailure() throws Exception {
    RuntimeException expected = new RuntimeException();
    FakeClusterManager clusterManager = new FakeClusterManager() {

        @Override
        public void nodeListener(NodeListener listener) {
            // Triggers HAManager init failure
            throw expected;
        }
    };
    VertxOptions options = new VertxOptions().setClusterManager(clusterManager).setHAEnabled(true);
    Throwable failure = failStart(options);
    assertSame(expected, failure);
}
