Method Detail

getProtocol

protected SpdyOrHttpChooser.SelectedProtocol getProtocol(SSLEngine engine)

Return the SpdyOrHttpChooser.SelectedProtocol for the SSLEngine. If its not known yet implementations MUST return SpdyOrHttpChooser.SelectedProtocol.UNKNOWN.

decode

protected void decode(ChannelHandlerContext ctx,
          ByteBuf in,
          List<Object> out)
               throws Exception

Description copied from class: ByteToMessageDecoder

Decode the from one ByteBuf to an other. This method will be called till either the input ByteBuf has nothing to read when return from this method or till nothing was read from the input ByteBuf.

Specified by:

decode in class ByteToMessageDecoder

Parameters:

ctx - the ChannelHandlerContext which this ByteToMessageDecoder belongs to

in - the ByteBuf from which to read data

out - the List to which decoded messages should be added

Throws:

Exception - is thrown if an error accour

addSpdyHandlers

protected void addSpdyHandlers(ChannelHandlerContext ctx,
                   SpdyVersion version)

Add all ChannelHandler's that are needed for SPDY with the given version.

addHttpHandlers

protected void addHttpHandlers(ChannelHandlerContext ctx)

Add all ChannelHandler's that are needed for HTTP.

createHttpRequestHandlerForHttp

protected abstract ChannelHandler createHttpRequestHandlerForHttp()

Create the ChannelHandler that is responsible for handling the http requests when the SpdyOrHttpChooser.SelectedProtocol was SpdyOrHttpChooser.SelectedProtocol.HTTP_1_0 or SpdyOrHttpChooser.SelectedProtocol.HTTP_1_1

createHttpRequestHandlerForSpdy

protected ChannelHandler createHttpRequestHandlerForSpdy()

Create the ChannelHandler that is responsible for handling the http responses when the when the SpdyOrHttpChooser.SelectedProtocol was SpdyOrHttpChooser.SelectedProtocol.SPDY_3_1. By default this getMethod will just delecate to createHttpRequestHandlerForHttp(), but sub-classes may override this to change the behaviour.
