Constructor Detail

TCEdge

public TCEdge()

Constructs an empty edge.

TCEdge

public TCEdge(Object userObject)

Constructs an edge that holds a reference to the specified user object.

Parameters:

userObject - reference to the user object

TCEdge

public TCEdge(Object userObject,
              boolean allowsChildren)

Constructs an edge that holds a reference to the specified user object and sets default values for points and the label position.

Parameters:

userObject - reference to the user object

Method Detail

changeAttributes

public Map changeAttributes(Map change)

Override parent method to ensure non-null points.

Specified by:

changeAttributes in interface org.jgraph.graph.GraphCell

getSource

public Object getSource()

Returns the source of the edge.

Specified by:

getSource in interface org.jgraph.graph.Edge

getTarget

public Object getTarget()

Returns the target of the edge.

Specified by:

getTarget in interface org.jgraph.graph.Edge

setSource

public void setSource(Object port)

Sets the source of the edge.

Specified by:

setSource in interface org.jgraph.graph.Edge

setTarget

public void setTarget(Object port)

Returns the target of edge.

Specified by:

setTarget in interface org.jgraph.graph.Edge

createInsertEdit

public void createInsertEdit(List toInsert,
                             Map viewMap)

Insert into list additional cells to be created with this TCEdge and inserts their attributes to the viewMap. Intended for Graphmodel.insert.

Parameters:

toInsert - List of additional cells to be created with this TCObject

viewMap - attributes to be supplied to their views

clone

public Object clone()

Create a clone of the cell. The cloning of the user object is deferred to the cloneUserObject() method.

Returns:

Object a clone of this object.

acceptsSource

public abstract boolean acceptsSource(TCPort port)

Returns whether the edge can accept given port as its source

Parameters:

port - port to decide whether to be accepted as source

Returns:

whether the port is accepted

acceptsTarget

public abstract boolean acceptsTarget(TCPort port)

Returns whether the edge can accept given port as its target

Parameters:

port - port to decide whether to be accepted as target

Returns:

whether the port is accepted

createDefaultView

public TCEdgeView createDefaultView(TCGraph g,
                                    org.jgraph.graph.CellMapper cm)

Creates default view object for this TCEdge.

Parameters:

g - graph to create view on

cm - used CellMapper

Returns:

created TCEdgeView
