Examples of com.sun.sgs.impl.sharedutil.MessageBuffer

com.sun.sgs.impl.sharedutil.MessageBuffer
A buffer for composing/decomposing messages.
Strings are encoded in modified UTF-8 format as described in {@link java.io.DataInput}.


                byte[] payload = new byte[message.remaining()];
                message.get(payload);


                // Dispatch
    MessageBuffer msg = new MessageBuffer(payload);
    byte opcode = msg.getByte();
    
    if (logger.isLoggable(Level.FINEST)) {
        logger.log(
      Level.FINEST,
      "processing opcode 0x{0}",
