Class AbstractEdge

  net.sourceforge.fluxion.graph.AbstractEdge

All Implemented Interfaces:

Edge

Direct Known Subclasses:

IsAEdge, NestedEdge, ValueEdge, WalkEdge

public abstract class AbstractEdge
extends java.lang.Object
implements Edge

An abstract implementation of Edge which provides common implementations os the setter and getter methods defined by this interface. Unless you have a specific reason to, it is best to subclass this class and use the standard implementations when defining a new Edge instead of implementing Edge directly. Using this approach, all that is needed is to define how the new Edge handles owl properties.

AbstractEdge

public AbstractEdge()

Method Detail

setLabel

public void setLabel(java.lang.String label)

Description copied from interface: Edge

Sets the String to use as a label. This is optional, and is used for clarity when drawing the graph illustration only.

Specified by:

setLabel in interface Edge

Parameters:

label - the label on this edge

getLabel

public java.lang.String getLabel()

Description copied from interface: Edge

A String to use as the label for this Edge when drawn on the graph.

Specified by:

getLabel in interface Edge

Returns:

the label

setHeadNode

public void setHeadNode(Node head)

Description copied from interface: Edge

Set the Node at the head of this Edge. This method is very important for describing the structure of the graph. Nodes can be freely added to the graph, as can edges, but without careful sturcturing of ehad and tail nodes on an edge the graph will have no sensible structure.

Specified by:

setHeadNode in interface Edge

Parameters:

head - the node at the head of this edge

getHeadNode

public Node getHeadNode()

Description copied from interface: Edge

Return the Node at the head of this Edge.

Specified by:

getHeadNode in interface Edge

Returns:

the head node

setTailNode

public void setTailNode(Node tail)

Description copied from interface: Edge

Set the Node at the tail of this Edge. This method is very important for describing the structure of the graph. Nodes can be freely added to the graph, as can edges, but without careful sturcturing of ehad and tail nodes on an edge the graph will have no sensible structure.

Specified by:

setTailNode in interface Edge

Parameters:

tail - the node at the tail of this edge

getTailNode

public Node getTailNode()

Description copied from interface: Edge

Return the Node at the tail of this Edge.

Specified by:

getTailNode in interface Edge

Returns:

the tail node

accept

public void accept(EdgeVisitor visitor)

Specified by:

accept in interface Edge
