Class MyWidthCalculator

java.lang.Object
  be.ac.ulg.montefiore.run.totem.domain.model.DomainChangeAdapter
      be.ac.ulg.montefiore.run.totem.visualtopo.graph.MyWidthCalculator

All Implemented Interfaces:

DomainChangeListener, WidthCalculator

public class MyWidthCalculator
extends DomainChangeAdapter
implements WidthCalculator

Calculate the width of a link given its bandwidth.

The width is calculated relative to the minimum and maximum link capacity in the network. The returned width is between 1 and 6 pixel. The class listens to domain changes (add link, remove link, bandwidth change) and adapt the width accordingly.
The virtual links are not taken into account.
