Description copied from class: ReplayingDecoder

Decodes the received packets so far into a frame.

Specified by:

decode in class ReplayingDecoder<SocksCmdRequestDecoder.State>

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
