Class Tee

java.lang.Object
  net.clackrouter.component.base.ClackComponent
      net.clackrouter.component.extension.Tee

All Implemented Interfaces:

Alarm

public class Tee
extends ClackComponent

A simple class to take a packet on a single input and duplicate it and send the packet out two outputs.

This class currently only works for packets of known types, including:

• VNSEthernetPacket
• VNSARPPacket
• VNSIPPacket
• VNSICMPPacket
• VNSTCPPacket
• VNSUDPPacket

Method Summary

void	acceptPacket(VNSPacket packet, int port_number) The starting point for packet-processing when packets are "pushed" to this component.
boolean	isModifying() Reports whether this component modifies packets passed through it This value is used by the static checking algorithm used to make sure port connections are valid.
protected void	setupPorts(int numports) Allocates an array of ClackPort objects to be used by this component

Method Detail

setupPorts

protected void setupPorts(int numports)

Description copied from class: ClackComponent

Allocates an array of ClackPort objects to be used by this component

Overrides:

setupPorts in class ClackComponent

Parameters:

numports - the number of ports to create

isModifying

public boolean isModifying()

Description copied from class: ClackComponent

Reports whether this component modifies packets passed through it This value is used by the static checking algorithm used to make sure port connections are valid. Sub-classes that do not modify packets should override this method

Overrides:

isModifying in class ClackComponent

Returns:

by default, we assume the component modifies packets

acceptPacket

public void acceptPacket(VNSPacket packet,
                         int port_number)

Description copied from class: ClackComponent

The starting point for packet-processing when packets are "pushed" to this component.

The default implementation warns that the packet is being ignored.

Overrides:

acceptPacket in class ClackComponent

Parameters:

packet - The pushed packet

port_number - The number of the port that this packet is arriving on
