WebSocket07Channel

public WebSocket07Channel(org.xnio.StreamConnection channel,
                          ByteBufferPool bufferPool,
                          java.lang.String wsUrl,

                          org.xnio.OptionMap options)

Create a new WebSocket07Channel

Parameters:

channel - The StreamConnection over which the WebSocket Frames should get send and received. Be aware that it already must be "upgraded".

bufferPool - The ByteBufferPool which will be used to acquire ByteBuffer's from.

wsUrl - The url for which the WebSocket07Channel was created.

Method Detail

receiveFrame

protected WebSocketChannel.PartialFrame receiveFrame()

Description copied from class: WebSocketChannel

Create a new StreamSourceFrameChannel which can be used to read the data of the received Frame

Specified by:

receiveFrame in class WebSocketChannel

Returns:

channel A StreamSourceFrameChannel will be used to read a Frame from. This will return null if the right StreamSourceFrameChannel could not be detected with the given buffer and so more data is needed.

markReadsBroken

protected void markReadsBroken(java.lang.Throwable cause)

Description copied from class: AbstractFramedChannel

Called when a source sub channel fails to fulfil its contract, and leaves the channel in an inconsistent state.

The underlying read side will be forcibly closed.

Overrides:

markReadsBroken in class WebSocketChannel

Parameters:

cause - The possibly null cause

closeSubChannels

protected void closeSubChannels()

Description copied from class: AbstractFramedChannel

Method that is called when the channel is being forcibly closed, and all sub stream sink/source channels should also be forcibly closed.

Specified by:

closeSubChannels in class AbstractFramedChannel<WebSocketChannel,StreamSourceFrameChannel,StreamSinkFrameChannel>

createStreamSinkChannel

protected StreamSinkFrameChannel createStreamSinkChannel(WebSocketFrameType type)

Description copied from class: WebSocketChannel

Create a new StreamSinkFrameChannel which can be used to send a WebSocket Frame of the type WebSocketFrameType.

Specified by:

createStreamSinkChannel in class WebSocketChannel

Parameters:

type - The WebSocketFrameType of the WebSocketFrame which will be send over this StreamSinkFrameChannel
