Method Detail

getOWLClass

OWLClass getOWLClass()

Gets the class which is equivalent to the disjoint union.

Returns:

the class that is equivalent to a disjoint union of other classes.

getClassExpressions

java.util.Set<OWLClassExpression> getClassExpressions()

Gets the class expressions which are operands of the disjoint union.

Returns:

A Set containing the operands of the disjoint union, note that this does not include the OWLClass that is equivalent to the disjoint union.

getOWLEquivalentClassesAxiom

OWLEquivalentClassesAxiom getOWLEquivalentClassesAxiom()

Gets the part of this axiom that corresponds to an EquivalentClasses axiom.

Returns:

The equivalent classes axiom part of this axiom. This is essentially, EquivalentClasses(CE, CEUnion) where CEUnion is the union of the classes returned by the getClassExpressions() method and CE is the class returned by the getOWLClass() method.

getOWLDisjointClassesAxiom

OWLDisjointClassesAxiom getOWLDisjointClassesAxiom()

Gets the part of this axiom that corresponds to an DisjointClasses axiom.

Returns:

The disjoint classes axiom part of this axiom. This is essentially, DisjointClasses(CE1, ..., CEn) where CEi in {CE1, ..., CEn} is contained in the classes returned by the getClassExpressions() method.

getAxiomWithoutAnnotations

OWLDisjointUnionAxiom getAxiomWithoutAnnotations()

Description copied from interface: OWLAxiom

Gets an axiom that is structurally equivalent to this axiom without annotations. This essentially returns a version of this axiom stripped of any annotations

Specified by:

getAxiomWithoutAnnotations in interface OWLAxiom

Returns:

The annotationless version of this axiom
