Class ENCTreeModel

java.lang.Object
  fi.helsinki.dacopan.model.ENCTreeModel

public class ENCTreeModel
extends java.lang.Object

This class encloses the model of an encapsulation tree. It provides the services that are needed by the ENC animation to properly display the encapsulation animation of a particular transfer unit. The class is instantiated each time an encapsulation is to be shown, and constructed with transfer unit or the unit itself. Normally we wouldn't care who authors our classes, but this one is a little bit tricky. Ask Jonathan or Jarkko if you need to understand this in more depth.

Nested Class Summary

static class	ENCTreeModel.DrawableEncLayer This inner class encloses the concept of a single layer that's going to be drawn in the ENC animation.
static class	ENCTreeModel.DrawableTransferUnit This inner class encloses the concept of a single unit that's going to be drawn in the ENC animation.
