public class Link

extends Component

The base class for modeling a physical link. While one may extend this class to provide sophisticated link models, this class implements a simple multi-endpoint link. Data injected from one end point is propagated to all the other end points. The propagation delay is the same for all the end points.

The ports in the Link are numbered from 0, i.e., "0", "1", "2" etc.

Method Detail

process

protected void process(java.lang.Object data_,
                       Port inPort_)

Description copied from class: Component

The main callback method of a component. Being invoked when data arrives at a port of its.

Overrides:

process in class Component

Following copied from class: drcl.comp.Component

Parameters:

data_ - the arrival data.

inPort_ - the port where the data arrives.

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: Component

Duplicates the content of source_, including ID, name, child components and connections among them, to this component. Subclasses need to override this method to copy its own variables.

Overrides:

duplicate in class Component

attach

public void attach(Node n1_,
                   Node n2_)

attach

public void attach(Port p1_,
                   Port p2_)

getPropDelay

public double getPropDelay()

Returns the propagation delay of the link.

Returns:

the propagation delay of the link.

setPropDelay

public void setPropDelay(double delay_)

Sets the propagation delay of the link.

Parameters:

delay_ - the new delay value.
