public class ConceptRelation
extends ComponentRelation

A relation between concepts in an ontology. This class is really only used to connect the FiniteConcepts in the Ontology class, which corresponds to the relations that a user draws in the Ontology Editor in Vergil. This information is also then used to generate the ordering relations when a ConceptGraph is created.

Field Detail

annotation

public StringParameter annotation

An annotation that describes the transition. If this is non-empty, then a visual editor will be expected to put this annotation on or near the transition to document its function. This is a string that defaults to the empty string. Note that it can reference variables in scope using the notation $name.

color

public ColorAttribute color

Color in which to render this transition. The default color is black.

dashed

public Parameter dashed

Indicator that this transition should be rendered as a dashed line. This is a boolean that defaults to false.

exitAngle

public Parameter exitAngle

Attribute the exit angle of a visual rendition. This parameter contains a DoubleToken, initially with value 0.0. It must lie between -PI and PI. Otherwise, it will be truncated to lie within this range.

gamma

public Parameter gamma

Attribute giving the orientation of a self-loop. This is equal to the tangent at the midpoint (more or less). This parameter contains a DoubleToken, initially with value 0.0.

Constructor Detail

ConceptRelation

public ConceptRelation(Ontology container,
                       java.lang.String name)
                throws IllegalActionException,
                       NameDuplicationException

Construct a ConceptRelation with the given name contained by the specified entity. The container argument must not be null, or a NullPointerException will be thrown. This ConceptRelation will use the workspace of the container for synchronization and version counts. If the name argument is null, then the name is set to the empty string.

Parameters:

container - The container.

name - The name of the ConceptRelation.

Throws:

IllegalActionException - If the container is incompatible with this ConceptRelation.

NameDuplicationException - If the name coincides with any relation already in the container.

ConceptRelation

public ConceptRelation(Workspace workspace)
                throws IllegalActionException,
                       NameDuplicationException

Construct a ConceptRelation in the given workspace with an empty string as a name. If the workspace argument is null, use the default workspace. The object is added to the workspace directory. Increment the version of the workspace.

Parameters:

workspace - The workspace for synchronization and version tracking.

Throws:

IllegalActionException - If the container is incompatible with this ConceptRelation.

NameDuplicationException - If the name coincides with any relation already in the container.

Method Detail

getLabel

public java.lang.String getLabel()

Return the value of the annotation parameter.

Returns:

The value of the annotation parameter, or a string "ERROR" if the parameter cannot be evaluated.

setContainer

public void setContainer(CompositeEntity container)
                  throws IllegalActionException,
                         NameDuplicationException

Override the base class to ensure that the proposed container is an instance of Ontology or null.

Overrides:

setContainer in class ComponentRelation

Parameters:

container - The proposed container.

Throws:

IllegalActionException - If the argument is not an Ontology or null.

NameDuplicationException - If the container already has a relation with the name of this relation.

See Also:

ComponentRelation.getContainer()

_checkPort

protected void _checkPort(Port port)
                   throws IllegalActionException

Throw an exception if the port cannot be linked to this relation.

Overrides:

_checkPort in class ComponentRelation

Parameters:

port - The port to be checked to see if the relation can be attached

Throws:

IllegalActionException - If the port's container is not a FiniteConcept.
