Class DefaultPort

public class DefaultPort extends DefaultGraphCell implements Port

A simple implementation for a port.

Field Summary
protected Port	anchor Reference to the anchor of this port
protected HashSet	edges Edges that are connected to the port

Constructor Summary
	DefaultPort() Constructs an empty port.
	DefaultPort(Object userObject) Constructs a port that holds a reference to the specified user object.
	DefaultPort(Object userObject, Port anchor) Constructs a port that holds a reference to the specified user object and a reference to the specified anchor.

Method Summary
boolean	addEdge(Object edge) Adds `edge` to the list of edges.
Object	clone() Create a clone of the cell.
Iterator	edges() Returns an iterator of the edges connected to the port.
Port	getAnchor() Returns the anchor of this port.
Set	getEdges() Returns the collection of edges connected to this port.
boolean	removeEdge(Object edge) Removes `edge` from the list of edges.
void	setAnchor(Port port) Sets the anchor of this port.
void	setEdges(Set edges) Sets the collection of edges connected to this port.

Field Detail

anchor

protected Port anchor

Reference to the anchor of this port

edges

protected HashSet edges

Edges that are connected to the port

Constructor Detail

DefaultPort

public DefaultPort()

Constructs an empty port.

DefaultPort

public DefaultPort(Object userObject)

Constructs a port 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 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

addEdge

public boolean addEdge(Object edge)

Adds edge to the list of edges.

clone

public Object clone()

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

Returns an iterator of the edges connected to the port.

getAnchor

public Port getAnchor()

Returns the anchor of this port.

getEdges

public Set getEdges()

Returns the collection of edges connected to this port.

removeEdge

public boolean removeEdge(Object edge)

Removes edge from the list of edges.

setAnchor

public void setAnchor(Port port)

Sets the anchor of this port.

setEdges

public void setEdges(Set edges)

Sets the collection of edges connected to this port.
