public class ClassDiagramGraphModel
extends UMLMutableGraphSupport
implements java.beans.VetoableChangeListener

This class defines a bridge between the UML meta-model representation of the design and the GraphModel interface used by GEF. This class handles only UML Class digrams.

protected static Category cat

_model

protected MNamespace _model
The "home" UML model of this diagram, not all ModelElements in this graph are in the home model, but if they are added and don't already have a model, they are placed in the "home model". Also, elements from other models will have their FigNodes add a line to say what their model is.

Constructor Detail

ClassDiagramGraphModel

public ClassDiagramGraphModel()
Method Detail

getNamespace

public MNamespace getNamespace()

setNamespace

public void setNamespace(MNamespace m)

getPorts

public java.util.Vector getPorts(java.lang.Object nodeOrEdge)
Return all ports on node or edge


getOwner

public java.lang.Object getOwner(java.lang.Object port)
Return the node or edge that owns the given port


getInEdges

public java.util.Vector getInEdges(java.lang.Object port)
Return all edges going to given port (read Model Element). Instances can't currently be added to a class diagram.


getOutEdges

public java.util.Vector getOutEdges(java.lang.Object port)
Return all edges going from given port (model element)


getSourcePort

public java.lang.Object getSourcePort(java.lang.Object edge)
Return one end of an edge


getDestPort

public java.lang.Object getDestPort(java.lang.Object edge)
Return the other end of an edge


canAddNode

public boolean canAddNode(java.lang.Object node)
Return true if the given object is a valid node in this graph


canAddEdge

public boolean canAddEdge(java.lang.Object edge)
Return true if the given object is a valid edge in this graph


addNode

public void addNode(java.lang.Object node)
Add the given node to the graph, if valid.


addEdge

public void addEdge(java.lang.Object edge)
Add the given edge to the graph, if valid.


addNodeRelatedEdges

public void addNodeRelatedEdges(java.lang.Object node)
Adds the edges from the given node. For example, this method lets you add an allready existing massociation between two figclassifiers.

vetoableChange

public void vetoableChange(java.beans.PropertyChangeEvent pce)
Specified by:
vetoableChange in interface java.beans.VetoableChangeListener

canChangeConnectedNode

public boolean canChangeConnectedNode(java.lang.Object newNode,
                                      java.lang.Object oldNode,
                                      java.lang.Object edge)
When rerouting an edge, this is the first method to be called by SelectionRerouteEdge, in order to determine whether the graphmodel will allow the change.

restricted to class<->association changes for now.

Parameters:
newNode - this is the new node that one of the ends is dragged to.
oldNode - this is the existing node that is already connected.
edge - this is the edge that is being dragged/rerouted
Returns:
whether or not the rerouting is allowed

changeConnectedNode

public void changeConnectedNode(java.lang.Object newNode,
                                java.lang.Object oldNode,
                                java.lang.Object edge,
                                boolean isSource)
Reroutes the connection to the old node to be connected to the new node. delegates to rerouteXXX(,,,) for each of the 4 possible edges in a class diagram: Association, Dependency, Generalization, Link.

Parameters:
newNode - this is the new node that one of the ends is dragged to.
oldNode - this is the existing node that is already connected.
edge - this is the edge that is being dragged/rerouted
isSource - tells us which end is being rerouted.
