Field Detail

TEXT_WIDTH

public static int TEXT_WIDTH

TEXT_HEIGHT

public static int TEXT_HEIGHT

referent

Referent referent

The concepts' referent (possibly null)

refDone

boolean refDone

Whether the type and referent are current

Constructor Detail

Concept

public Concept()

Instantiates a default concept with label "T".

Method Detail

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class GNode

Throws:

Throwable

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)

Draws a concept on the given graphics context. Draws the box, label, shadows (if any).

Overrides:

draw in class GNode

Parameters:

g - graphics context on which to draw

printing - (ignored; appears for consistency only)

parseTextLabel

public void parseTextLabel()

Breaks up text label into its constituents, removes leading and trailing spaces, and replaces all embedded spaces with underscore '_' characters. Bears no relationship to the notio referent.

getTypeLabel

public String getTypeLabel()

Get just the type label portion of the concept's text label.

Overrides:

getTypeLabel in class GNode

Returns:

a type label

setTextLabel

public void setTextLabel(String label)

Define a complete text label for the concept; type and referent are extracted.

Overrides:

setTextLabel in class GraphObject

Parameters:

label - The new text label for the concept

setTypeLabel

public void setTypeLabel(String newlabel)

Overrides:

setTypeLabel in class GNode

setTypeLabel

public void setTypeLabel(String newlabel,
                         boolean resize)

Define the type label for the concept. Referent is unaffected.

Overrides:

setTypeLabel in class GNode

Parameters:

newlabel - type label only.

resize - whether to bother with adjusting the concept's size or not.

setReferent

public void setReferent(String newref)

setReferent

public void setReferent(String newref,
                        boolean changing)

Sets this concept's referent designator as a string.

Parameters:

newref - the string for the new referent

changing - whether to look for changes in a referent; * if true then try resizing concept, etc. Need to indicate whether the referent is changing; otherwise every setting of a referent (including initial value setting) will force resizing, which may not make sense if the concept doesn't even have a size yet.

getReferent

public String getReferent()

Finds the referent part of this concept's text label. "parses" the label, setting both the type and referent part.

Returns:

Concept's referent designator as a string. If there's no referent, returns empty string (""), not null.

See Also:

parseTextLabel()

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 -
