All Implemented Interfaces:

ChannelHandler, ChannelUpstreamHandler, LifeCycleAwareChannelHandler

Deprecated.

Use org.jboss.netty.handler.codec.http.websocketx instead. Decodes ChannelBuffers into WebSocketFrames.

For the detailed instruction on adding add Web Socket support to your HTTP server, take a look into the WebSocketServer example located in the org.jboss.netty.example.http.websocket package.

WebSocketFrameDecoder

public WebSocketFrameDecoder(int maxFrameSize)

Deprecated.

Creates a new instance of WebSocketFrameDecoder with the specified maxFrameSize. If the client sends a frame size larger than maxFrameSize, the channel will be closed.

Parameters:

maxFrameSize - the maximum frame size to decode

Method Detail

protected Object decode(ChannelHandlerContext ctx,
            Channel channel,
            ChannelBuffer buffer,

Deprecated.

Description copied from class: ReplayingDecoder

Decodes the received packets so far into a frame.

Specified by:

decode in class ReplayingDecoder<VoidEnum>

Parameters:

ctx - the context of this handler

channel - the current channel

buffer - the cumulative buffer of received packets so far. Note that the buffer might be empty, which means you should not make an assumption that the buffer contains at least one byte in your decoder implementation.

state - the current decoder state (null if unused)

Returns:

the decoded frame

Throws:

Exception
