                          Ontology anOntology)

Convenience constructor for simple cases where the domain and range are single classes.

Parameters:

aName - the name of the property.

aDomainClass - the class representing the domain.

aRange - the class representing the range.

anOntology - the ontology this property belongs to.

ObjectPropertyImpl

public ObjectPropertyImpl(String name,
                          String comment,
                          Set aDomain,

Method Detail

addSuperProperty

public void addSuperProperty(Property property)

Description copied from interface: Property

Adds a SubPropertyOf relation between the given property and this.

Specified by:

addSuperProperty in interface Property

Overrides:

addSuperProperty in class PropertyImpl

isValidRange

public boolean isValidRange(OInstance instance)

Specified by:

isValidRange in interface ObjectProperty

Parameters:

instance -

Returns:

true if this value is compatible with the range restrictions on the property. False otherwise.

getRange

public Set getRange()

Description copied from class: PropertyImpl

Returns the set of range classes for this property. This is composed from the classes declared as range restriction for this property plus all the range restrictions from the super-properties.

Specified by:

getRange in interface Property

Overrides:

getRange in class PropertyImpl

Returns:

a set of OClass or Class objects.

getInverseProperties

public Set getInverseProperties()

Description copied from interface: ObjectProperty

Returns the set of inverse properties for this property. Null if no such properties. The set contains objects of KBProperty instances.

Specified by:

getInverseProperties in interface ObjectProperty

Returns:

a Set value.

setInverseOf

public void setInverseOf(Property theInverse)

Description copied from interface: ObjectProperty

Set theInverse as inverse property to this property.

Specified by:

setInverseOf in interface ObjectProperty
