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

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
