Parameters:

Method Detail

getOrderedExplanation

public ExplanationTree getOrderedExplanation(OWLAxiom entailment,
                                             Set<OWLAxiom> axioms)

Description copied from interface: ExplanationOrderer

Gets an ordered (and possibly indented) explanation. The orderer really provides some kind of "presentation" layer to make an explanation easier to read.

Specified by:

getOrderedExplanation in interface ExplanationOrderer

Parameters:

entailment - The axiom that represents the entailment that the explanation being ordered is a justification for.

axioms - The axioms that constitute the unordered explanation

Returns:

An order explanation.

getAxiomsForLHS

protected Set<OWLAxiom> getAxiomsForLHS(OWLEntity lhs)

Gets axioms that have a LHS corresponding to the specified entity.

Parameters:

lhs - The entity that occurs on the left hand side of the axiom.

Returns:

A set of axioms that have the specified entity as their left hand side.

indexAxiomsByRHSEntities

protected void indexAxiomsByRHSEntities(OWLObject rhs,
                                        OWLAxiom axiom)
