Method Summary

Modifier and Type	Method and Description
Set<OWLDifferentIndividualsAxiom>	asPairwiseAxioms() Gets this axiom as a set of pairwise axioms; if the axiom contains only two operands, the axiom itself is returned unchanged, including its annotations.
boolean	containsAnonymousIndividuals() Determines whether this axiom contains anonymous individuals.
OWLDifferentIndividualsAxiom	getAxiomWithoutAnnotations() Gets an axiom that is structurally equivalent to this axiom without annotations.
Set<OWLDifferentIndividualsAxiom>	splitToAnnotatedPairs() Splits this axiom to pairs, including annotations.

Method Detail

getAxiomWithoutAnnotations

@Nonnull
OWLDifferentIndividualsAxiom 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 axiom deprived of annotations

containsAnonymousIndividuals

boolean containsAnonymousIndividuals()

Determines whether this axiom contains anonymous individuals. Anonymous individuals are not allowed in different individuals axioms.

Returns:

true if this axioms contains anonymous individual axioms

asPairwiseAxioms

@Nonnull
Set<OWLDifferentIndividualsAxiom> asPairwiseAxioms()

Description copied from interface: OWLNaryAxiom

Gets this axiom as a set of pairwise axioms; if the axiom contains only two operands, the axiom itself is returned unchanged, including its annotations. Note that, aside from this exception, annotations on this axiom will not be copied to each axiom returned in the set of pairwise axioms.
Note: This will contain all pairs, i.e., for the set "a, b, c" the pairs "a, b", "a, c", "b, c" will be returned. For some applications, only "a, b", "b, c" are required.

Specified by:

asPairwiseAxioms in interface OWLNaryAxiom<OWLIndividual>

Returns:

This axiom as a set of pairwise axioms.

splitToAnnotatedPairs

@Nonnull
Set<OWLDifferentIndividualsAxiom> splitToAnnotatedPairs()

Description copied from interface: OWLNaryAxiom

Splits this axiom to pairs, including annotations. This method implements the process described at http://www.w3.org/TR/owl2-mapping-to-rdf/# Axioms_that_are_Translated_to_Multiple_Triples which is used, for example, in serializing EquivalentProperty axioms with three operands. Note that annotations on this axiom will be copied to each axiom returned in the set of pairwise axioms. Note: This will contain only the "An, An+1" pairs, i.e., for the set "a, b, c" the pairs "a, b" and "b, c" will be returned, but not "a, c".

Specified by:

splitToAnnotatedPairs in interface OWLNaryAxiom<OWLIndividual>

Returns:

This axiom as a set of pairwise axioms, annotations included.
