Constructor Detail

RelationLabel

public RelationLabel()

Instantiates a relation type with default label "link".

RelationLabel

public RelationLabel(String label)

Instantiates a relation type with the given label.

Parameters:

label - the relation label's string value

Method Detail

init

private void init(String label)

getShape

public Shape getShape()

Description copied from class: GraphObject

Obtain the Shape object that represents the selectable region of this object.

Specified by:

getShape in class GraphObject

Returns:

the Shape for this object, with appropriate dimensions, etc.

See Also:

GraphObject.getShape()

draw

public void draw(Graphics2D g,
                 boolean printing)

Description copied from class: GNode

Handles generic drawing for all nodes, and usually invokes the node's class method "draw"

Overrides:

draw in class GNode

Parameters:

g - Graphics context on which the object is to be rendered

printing - Whether to pretty-print the object

setTextLabel

public void setTextLabel(String label)

Sets the text label of this relation. If there's a ":", then it and subsequent characters are ignored.

Overrides:

setTextLabel in class GraphObject

Parameters:

label - new text label (erases the old text label)

commitToKnowledgeBase

public boolean commitToKnowledgeBase(KnowledgeBase kb)

Perform whatever activities are required for this concept to be committed to a knowledge base. Adds the type label to the type hierarchy if it is not already there.

Overrides:

commitToKnowledgeBase in class GraphObject

Parameters:

kb -

UnCommitFromKnowledgeBase

public boolean UnCommitFromKnowledgeBase(KnowledgeBase kb)

Perform whatever activities are required for this concept to be committed to a knowledge base. Adds the type label to the type hierarchy.

Parameters:

kb -
