Constructor Detail

SpdyFrameDecoder

public SpdyFrameDecoder(int version)

Creates a new instance with the specified version and the default maxChunkSize (8192) and maxHeaderSize (16384).

SpdyFrameDecoder

public SpdyFrameDecoder(int version,
                int maxChunkSize,
                int maxHeaderSize)

Creates a new instance with the specified parameters.

SpdyFrameDecoder

protected SpdyFrameDecoder(int version,
                int maxChunkSize,
                org.jboss.netty.handler.codec.spdy.SpdyHeaderBlockDecoder headerBlockDecoder)

Method Detail

decodeLast

protected Object decodeLast(ChannelHandlerContext ctx,
                Channel channel,
                ChannelBuffer buffer)
                     throws Exception

Description copied from class: FrameDecoder

Decodes the received data so far into a frame when the channel is disconnected.

Overrides:

decodeLast in class FrameDecoder

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.

Returns:

the decoded frame if a full frame was received and decoded. null if there's not enough data in the buffer to decode a frame.

Throws:

Exception

decode

protected Object decode(ChannelHandlerContext ctx,
            Channel channel,
            ChannelBuffer buffer)
                 throws Exception

Description copied from class: FrameDecoder

Decodes the received packets so far into a frame. If an sub-class wants to extract a frame out of the buffer it should use the FrameDecoder.extractFrame(ChannelBuffer, int, int) method, to make optimizations easier later.

Specified by:

decode in class FrameDecoder

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.

Returns:

the decoded frame if a full frame was received and decoded. null if there's not enough data in the buffer to decode a frame.

Throws:

Exception
