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