Constructor Detail

EventObjectDecoder

public EventObjectDecoder(int maxFrameLength,
                  int lengthFieldOffset,
                  int lengthFieldLength,
                  int lengthAdjustment,
                  int initialBytesToStrip)

Creates a new instance.

Parameters:

maxFrameLength - the maximum length of the frame. If the length of the frame is greater than this value, TooLongFrameException will be thrown.

lengthFieldOffset - the offset of the length field

lengthFieldLength - the length of the length field

lengthAdjustment - the compensation value to add to the value of the length field

initialBytesToStrip - the number of first bytes to strip out from the decoded frame
