Class ChunkedMessageInput

java.lang.Object

org.drasyl.handler.stream.ChunkedMessageInput

All Implemented Interfaces:

io.netty.handler.stream.ChunkedInput<MessageChunk>

public class ChunkedMessageInput
extends Object
implements io.netty.handler.stream.ChunkedInput<MessageChunk>

Wraps each chunk of the specified io.netty.handler.stream.ChunkedInput<io.netty.buffer.ByteBuf> into a series of sortable MessageChunks, allowing the receiver to reassemble the ByteBuf in correct order. Useful for protocols that does provide message ordering (like UDP or drasyl).

  ChannelPipeline p = ...;

  p.addLast("encoder", new MessageChunkEncoder());
  p.addLast("chunked_write", new ChunkedWriteHandler);
  p.addLast("decoder", new MessageChunkDecoder());
  p.addLast("buffer", new MessageChunksBuffer(65536, 5000));
  p.addLast("aggregator", new ChunkedMessageAggregator(65536));
  ...
  p.addLast("handler", new MyReassembledMessageHandler());
