Examples of org.apache.thrift.protocol.TMessage

org.apache.thrift.protocol.TMessage
Helper class that encapsulates struct metadata.


        // Note that though setting message type to ONEWAY can be helpful when looking at packet
        // captures, some clients always send CALL and so servers are forced to rely on the "oneway"
        // attribute on thrift method in the interface definition, rather than checking the message
        // type.
        out.writeMessageBegin(new TMessage(name, oneway ? ONEWAY : CALL, sequenceId));


        // write the parameters
        TProtocolWriter writer = new TProtocolWriter(out);
        writer.writeStructBegin(name + "_args");
        for (int i = 0; i < args.length; i++) {
