model

private Object 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.

public Object getNamespace()

Specified by:

getNamespace in class UMLMutableGraphSupport

Returns:

the namespace of the diagram

See Also:

UMLMutableGraphSupport.getNamespace()

setNamespace

public void setNamespace(Object namespace)

Parameters:

namespace - the namespace to be set for this diagram

getPorts

public List getPorts(Object nodeOrEdge)

Specified by:

getPorts in interface org.tigris.gef.graph.GraphModel

See Also:

Return all ports on node or edge.

getOwner

public Object getOwner(Object port)

Specified by:

getOwner in interface org.tigris.gef.graph.BaseGraphModel

See Also:

Return the node or edge that owns the given port.

getInEdges

public List getInEdges(Object port)

Specified by:

getInEdges in interface org.tigris.gef.graph.GraphModel

See Also:

Return all edges going to given port (read Model Element). Instances can't currently be added to a class diagram.

getOutEdges

public List getOutEdges(Object port)

Specified by:

getOutEdges in interface org.tigris.gef.graph.GraphModel

See Also:

Return all edges going from given port (model element).

canAddNode

public boolean canAddNode(Object node)

Specified by:

canAddNode in interface org.tigris.gef.graph.MutableGraphModel

Overrides:

canAddNode in class UMLMutableGraphSupport

See Also:

Return true if the given object is a valid node in this graph.

canAddEdge

public boolean canAddEdge(Object edge)

Specified by:

canAddEdge in interface org.tigris.gef.graph.MutableGraphModel

Overrides:

canAddEdge in class UMLMutableGraphSupport

See Also:

Return true if the given object is a valid edge in this graph.

addNode

public void addNode(Object node)

Specified by:

addNode in interface org.tigris.gef.graph.MutableGraphModel

See Also:

Add the given node to the graph, if valid.

addEdge

public void addEdge(Object edge)

Add the given edge to the graph, if of the correct type. Throws IllegalArgumentException if edge is null or either of its ends are null.

Specified by:

addEdge in interface org.tigris.gef.graph.MutableGraphModel

See Also:

MutableGraphModel.addEdge(java.lang.Object)

addNodeRelatedEdges

public void addNodeRelatedEdges(Object node)

Adds the edges from the given node. For example, this method lets you add an allready existing massociation between two figclassifiers.

Specified by:

addNodeRelatedEdges in interface org.tigris.gef.graph.MutableGraphModel

Overrides:

addNodeRelatedEdges in class UMLMutableGraphSupport

See Also:

MutableGraphModel.addNodeRelatedEdges(Object)

vetoableChange

public void vetoableChange(PropertyChangeEvent pce)

Specified by:

vetoableChange in interface VetoableChangeListener

canChangeConnectedNode

public boolean canChangeConnectedNode(Object newNode,
                                      Object oldNode,
                                      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.

Specified by:

canChangeConnectedNode in interface org.tigris.gef.graph.MutableGraphModel

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(Object newNode,
                                Object oldNode,
                                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.

Specified by:

changeConnectedNode in interface org.tigris.gef.graph.MutableGraphModel

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.
