public class RNode
extends TMNode

An extension of TMNode acting as a Role Node (or R-Node) in a topic map graph. If a value is set by setEdge(GraphEdge), the RNode will be attached to the midpoint of the edge, and alter its length accordingly.

public GraphEdge edge

Constructor Detail

RNode

public RNode(String id)
      throws GraphException

Constructor with the required ID id value. With no edge specified, this floats free.

Throws:

GraphException

RNode

public RNode(String id,
             String label)
      throws GraphException

Constructor with the required ID id and label. With no edge specified, this floats free.

Throws:

GraphException

RNode

public RNode(Topic role,
             String id)
      throws GraphException

Constructor with an Topic role and a String ID id. With no edge specified, this floats free.

Throws:

GraphException

RNode

public RNode(Topic role,
             String id,
             String label)
      throws GraphException

Constructor with an Topic object role and Strings for ID id and label. With no edge specified, this floats free.

Throws:

RNode

public RNode(Topic role,
             GraphEdge edge,
             String id,
             String label)
      throws GraphException

Constructor with an Topic object role and Strings for ID id and label, as well as the anchor GraphEdge edge. It should be noted that the Topic ID is not used, and does not correspond with the ID used for the RNode since the Topic already may have a corresponding TNode. With no edge specified, this floats free.

Throws:

GraphException
