Constructor Detail


public ProcessSegment(TCB t,
                      Router router,
                      java.lang.String name)
Method Detail


public void reset(TCB t)


protected void setupPorts(int numports)
Description copied from class: ClackComponent
Allocates an array of ClackPort objects to be used by this component

setupPorts in class ClackComponent
numports - the number of ports to create


public void acceptPacket(VNSPacket packet,
                         int port_num)
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.

acceptPacket in class ClackComponent
packet - The pushed packet
port_num - The number of the port that this packet is arriving on
