Motivation: Currently, the SPDY frame encoding and decoding code is based upon the ChannelHandler abstraction. This requires maintaining multiple versions for 3.x and 4.x (and possibly 5.x moving forward). Modifications: The SPDY frame encoding and decoding code is separated from the ChannelHandler and SpdyFrame abstractions. Also test coverage is improved. Result: SpdyFrameCodec now implements the ChannelHandler abstraction and is responsible for creating and handling SpdyFrame objects.
