Method Detail

getAxiomWithoutAnnotations

OWLObjectPropertyAssertionAxiom 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

getSimplified

OWLObjectPropertyAssertionAxiom getSimplified()

Gets a simplified version of this object property axiom. This is defined recursively as follows:

• ObjectPropertyAssertion(P S O) = ObjectPropertyAssertion(P S O)
• ObjectPropertyAssertion(ObjectInverseOf(P) S O) = ObjectPropertyAssertion(P O S)

Returns:

isInSimplifiedForm

boolean isInSimplifiedForm()

Determines if this axiom is in a simplified form, i.e. a form where the property is not a property inverse. ObjectPropertyAssertion(P S O) is in a simplified form, where as ObjectPropertyAssertion(ObjectInverseOf(P) S O) is not because it contains an inverse object property.

Returns:

true if this axiom is in a simplified form, otherwise false
