org.jnetpcap.protocol.tcpip
Class TcpAssembler

java.lang.Object
  org.jnetpcap.packet.analysis.AbstractAnalyzer
      org.jnetpcap.protocol.tcpip.TcpAssembler

All Implemented Interfaces:

AnalyzerListener<FragmentSequenceEvent>, FragmentAssembler, JAnalyzer

public class TcpAssembler
extends AbstractAnalyzer
implements FragmentAssembler, AnalyzerListener<FragmentSequenceEvent>

Tcp reassembler. Assembles sequences of tcp segments into a contigues stream of data. TcpAssembler works with TcpSequencer to reassemble portions of the tcp segments. Higher level protocol must specify which portions of the tcp stream to reassemble.
