MessageToByteHandler

See also

• protocol ByteToMessageDecoder

  ByteToMessageDecoders decode bytes in a stream-like fashion from ByteBuffer to another message type.

• protocol WriteObservingByteToMessageDecoder

  Some ByteToMessageDecoders need to observe writes (which are outbound events). ByteToMessageDecoders which implement the WriteObservingByteToMessageDecoder protocol will be notified about every outbound write.

• enum DecodingState

  State of the current decoding process.

• class ByteToMessageHandler<Decoder>

  A handler which turns a given ByteToMessageDecoder into a ChannelInboundHandler that can then be added to a ChannelPipeline.

• protocol 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.

• class NIOSingleStepByteToMessageProcessor<Decoder>

  NIOSingleStepByteToMessageProcessor uses a NIOSingleStepByteToMessageDecoder to produce messages from a stream of incoming bytes. It works like ByteToMessageHandler but may be used outside of the channel pipeline. This allows processing of wrapped protocols in a general way.

• protocol MessageToByteEncoder

  A protocol for straightforward encoders which encode custom messages to ByteBuffers. To add a MessageToByteEncoder to a ChannelPipeline, use channel.pipeline.addHandler(MessageToByteHandler(myEncoder).
