NIOSingleStepByteToMessageDecoder
A simplified version of ByteToMessageDecoder that can generate zero or one messages for each invocation of decode or decodeLast. Having decode and decodeLast return an optional message avoids re-entrancy problems, since the functions relinquish exclusive access to the ByteBuffer when returning. This allows for greatly simplified processing.
protocol NIOSingleStepByteToMessageDecoder : ByteToMessageDecoderMany ByteToMessageDecoder’s can trivially be translated to NIOSingleStepByteToMessageDecoder’s. You should not implement ByteToMessageDecoder’s decode and decodeLast methods.
