Examples of org.apache.qpid.protocol.ProtocolEngine

org.apache.qpid.protocol.ProtocolEngine
A ProtocolEngine is a Receiver for java.nio.ByteBuffers. It takes the data passed to it in the received decodes it and then process the result.

                _header.flip();
                byte[] headerBytes = new byte[MINIMUM_REQUIRED_HEADER_BYTES];
                _header.get(headerBytes);




                ProtocolEngine newDelegate = null;
                byte[] newestSupported = null;


                for(int i = 0; newDelegate == null && i < _creators.length; i++)
                {


                    if(_supported.contains(_creators[i].getVersion()))
                    {
                        newestSupported = _creators[i].getHeaderIdentifier();
                        byte[] compareBytes = _creators[i].getHeaderIdentifier();
                        boolean equal = true;
                        for(int j = 0; equal && j<compareBytes.length; j++)
                        {
                            equal = headerBytes[j] == compareBytes[j];
                        }
                        if(equal)
                        {
                            newDelegate = _creators[i].getProtocolEngine();
                        }
                    }
                }


                // If no delegate is found then send back the most recent support protocol version id
                if(newDelegate == null)
                {
                    _networkDriver.send(ByteBuffer.wrap(newestSupported));


                    newDelegate = new ClosedDelegateProtocolEngine();
