Examples with ProtocolVersion org.apache.qpid.server.protocol.ProtocolVersion used on opensource projects

Example 1 with ProtocolVersion

use of org.apache.qpid.server.protocol.ProtocolVersion in project qpid-broker-j by apache.

the class AMQPConnection_0_8Impl method protocolInitiationReceived.

private synchronized void protocolInitiationReceived(ProtocolInitiation pi) {
    // this ensures the codec never checks for a PI message again
