All Implemented Interfaces:

EventListener, IPropertyChangeObject, PropertyChangeListener

public class ContainmentItem

extends PropertyChangeObject

implements PropertyChangeListener

this model class for the ContainmentView corresponds to the boxes in the graph that, in turn, correspond to the Resources that are connected to the main resource the display is centered around. All containmentItems are owned by a ContainmentSet which manages the set of items that are displayed by the Containment View that spread out from the central starting Resource.

A ContainmentItem also manages its Links to other ContainmentItems that present the containment information.

getToSet

public Set getToSet()

Set containing link items from this item to other Items.

printSets

public String printSets()

propertyChange

public void propertyChange(PropertyChangeEvent arg0)

this object monitors changes in its Resource, and when one happens of interest to it deals with it.
