Method Detail

getLength

public static int getLength(org.semanticweb.owlapi.model.OWLClassExpression ce)

Returns the length of a given class expression.

Parameters:

ce - the class expression

Returns:

the length of the class expression

getLength

public static int getLength(org.semanticweb.owlapi.model.OWLClassExpression ce,
                            OWLClassExpressionLengthMetric metric)

getDepth

public static int getDepth(org.semanticweb.owlapi.model.OWLClassExpression ce)

Returns the depth of a class expression.

Parameters:

ce - the class expression

Returns:

the depth of the class expression

getArity

public static int getArity(org.semanticweb.owlapi.model.OWLClassExpression ce)

Returns the arity of a class expression.

Parameters:

ce - the class expression

Returns:

the arity of the class expression

getChildren

public static Set<org.semanticweb.owlapi.model.OWLClassExpression> getChildren(org.semanticweb.owlapi.model.OWLClassExpression ce)

Returns all direct child expressions of a class expression.

Parameters:

ce - the class expression

Returns:

the direct child expressions

clone

public static org.semanticweb.owlapi.model.OWLClassExpression clone(org.semanticweb.owlapi.model.OWLClassExpression ce)

Returns a clone of the given class expression.

Parameters:

ce - the class expression

Returns:

a class expression clone

occursOnFirstLevel

public static boolean occursOnFirstLevel(org.semanticweb.owlapi.model.OWLClassExpression description,
                                         org.semanticweb.owlapi.model.OWLClassExpression cls)

Determine whether a named class occurs on the outermost level of a class expression, i.e. property depth 0 (it can still be at higher depth, e.g. if intersections are nested in unions)

Parameters:

description - the class expression

cls - the named class

Returns:

whether the named class occurs on the outermost level of the class expression
