Field Detail

edges

protected HashSet edges

Edges that are connected to the port

anchor

protected Port anchor

Reference to the anchor of this port

Constructor Detail

DefaultPort

public DefaultPort()

Constructs an empty port.

DefaultPort

public DefaultPort(Object userObject)

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

Parameters:

userObject - reference to the user object

DefaultPort

public DefaultPort(Object userObject,
                   Port anchor)

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

Parameters:

userObject - reference to the user object

anchor - to a a graphcell that constitutes the anchor

Method Detail

edges

public Iterator edges()

Returns an iterator of the edges connected to the port.

Specified by:

edges in interface Port

addEdge

public boolean addEdge(Object edge)

Adds edge to the list of ports.

Specified by:

addEdge in interface Port

removeEdge

public boolean removeEdge(Object edge)

Removes edge from the list of ports.

Specified by:

removeEdge in interface Port

getEdges

public Set getEdges()

Returns the anchor of this port.

setEdges

public void setEdges(Set edges)

Sets the anchor of this port.

getAnchor

public Port getAnchor()
