FramesDecoder	back to summary
public FramesDecoder(FramesDecoder.FrameProcessor frameProcessor) Creates Frame Decoder Parameters frameProcessor:FramesDecoder.FrameProcessor - callback for decoded frames

FramesDecoder

public FramesDecoder(FramesDecoder.FrameProcessor frameProcessor)

Creates Frame Decoder

Parameters

frameProcessor:FramesDecoder.FrameProcessor: - callback for decoded frames

FramesDecoder	back to summary

public FramesDecoder(FramesDecoder.FrameProcessor frameProcessor, int maxFrameSize)

Creates Frame Decoder

Parameters

frameProcessor:FramesDecoder.FrameProcessor: - callback for decoded frames

Method Detail

close	back to summary
public void close(String msg)

decode	back to summary
public void decode(ByteBuffer inBoundBuffer) throws IOException Adds the data from the given buffer, and performs frame decoding if possible. Either 1) appends the data from the given buffer to the current buffer ( if there is enough unused space ), or 2) adds it to the next buffer in the queue. If there is enough data to perform frame decoding then, all buffers are decoded and the FrameProcessor is invoked.
