Constructor Detail

DefaultPort

public DefaultPort()

Constructs an empty port.

DefaultPort

public DefaultPort(java.lang.Object userObject)

Constructs a port that holds a reference to the specified user object.

Parameters:

userObject - reference to the user object

DefaultPort

public DefaultPort(java.lang.Object userObject,
                   Port anchor)

Constructs a port that holds a reference to the specified user object and a reference to the specified anchor.

Parameters:

userObject - reference to the user object

anchor - reference to a graphcell that constitutes the anchor

Method Detail

edges

public java.util.Iterator edges()

Returns an iterator of the edges connected to the port.

Specified by:

edges in interface Port

addEdge

public boolean addEdge(java.lang.Object edge)

Adds edge to the list of edges.

Specified by:

addEdge in interface Port

removeEdge

public boolean removeEdge(java.lang.Object edge)

Removes edge from the list of edges.

Specified by:

removeEdge in interface Port

getEdges

public java.util.Set getEdges()

Returns the collection of edges connected to this port.

setEdges

public void setEdges(java.util.Set edges)

Sets the collection of edges connected to this port.

getAnchor

public Port getAnchor()

Returns the anchor of this port.

Specified by:

getAnchor in interface Port

setAnchor

public void setAnchor(Port port)

Sets the anchor of this port.

Specified by:

setAnchor in interface Port

clone

public java.lang.Object clone()

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

Overrides:

clone in class DefaultGraphCell

Returns:

Object a clone of this object.
