Detailed Description

To find packets in the TCP byte stream a pattern and the following toatl packet length are used.

Provides information about a specific pattern to find packets in the TCP stream

Constructor & Destructor Documentation

Construct a new Packetizer Base object from a given pattern.

Parameters

startPattern	A Buffer containing the bytes which mark the beginning of a packet
sizePosition	The 0 based index of the total size information in packet
sizeBytes	From how many bytes is the total size composed

pure virtual

Parameters

buf	reference to the buffer in which the packet should be found
bufferSize	the actual size of the buffer
offset	[out] if a packet was found the start offset of it
length	[out] if a packet was found the length of the packet(overall)
