Examples with PulsarHandler org.apache.pulsar.common.protocol.PulsarHandler used on opensource projects

Example 1 with PulsarHandler

use of org.apache.pulsar.common.protocol.PulsarHandler in project pulsar by apache.

the class ServerCnxTest method setConnectionVersion.

private void setConnectionVersion(int version) throws Exception {
    PulsarHandler cnx = serverCnx;
    Field versionField = PulsarHandler.class.getDeclaredField("remoteEndpointProtocolVersion");
    versionField.setAccessible(true);
    versionField.set(cnx, version);
}

Example 2 with PulsarHandler

use of org.apache.pulsar.common.protocol.PulsarHandler in project pulsar by apache.

the class BrokerClientIntegrationTest method testUnsupportedBatchMessageConsumer.

/**
 * It verifies that consumer which doesn't support batch-message:
 * <p>
 * 1. broker disconnects that consumer
 * <p>
 * 2. redeliver all those messages to other supported consumer under the same subscription
 *
