All Implemented Interfaces:

Alarm

public class Counter
extends ClackComponent

Simple component that transparently passes packets on to the next component , but graphically displays the number of packets that have passed through it.

Constructor Detail

Counter

public Counter(Router router,
               java.lang.String name)

Method Detail

setCounterView

public void setCounterView(CounterView v)

getCounterView

public CounterView getCounterView()

getMyUniqueCount

public int getMyUniqueCount()

setCLabel

public void setCLabel(java.lang.String cLabel)

set the label for the counter

getCLabel

public java.lang.String getCLabel()

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

resetCounter

public void resetCounter()

getPropertiesView

public javax.swing.JPanel getPropertiesView()

Description copied from class: ClackComponent

Method for getting the properties view associated with this component Property views are used to display more detailed information about internal component state. This method creates a default property view, and can be overriden to provide custom properties views

Overrides:

getPropertiesView in class ClackComponent

Returns:

this component's property view

getView

public VertexView getView(JGraph graph,
                          CellMapper mapper)

Override ClackComponent's method to provide for special drawing of the Counter with a CounterView object.

Overrides:

getView in class ClackComponent

Parameters:

graph - the Router Graph

mapper - the CellMapper associated with this Router Graph

Returns:

the VertexView for rendering this component
