Constructor Detail

SpdyHttpDecoder

public SpdyHttpDecoder(SpdyVersion version,
                       int maxContentLength)

Creates a new instance.

Parameters:

version - the protocol version

maxContentLength - the maximum length of the message content. If the length of the message content exceeds this value, a TooLongFrameException will be raised.
