StompBasedFrameDecoder

public StompBasedFrameDecoder(int maxLength,
                      boolean failFast)

Creates a new decoder.

Parameters:

maxLength - the maximum length of the decoded frame. A TooLongFrameException is thrown if the length of the frame exceeds this value.

failFast - If true, a TooLongFrameException is thrown as soon as the decoder notices the length of the frame will exceed maxFrameLength regardless of whether the entire frame has been read. If false, a TooLongFrameException is thrown after the entire frame that exceeds maxFrameLength has been read.
