Enum Constant Summary

Enum Constants

Enum Constant and Description
BOTTOM The SyntacticLocalityEvaluator for \bottom-locality: Locality class obtained when concepts and roles not present in the signature are given empty interpretations.
TOP The SyntacticLocalityEvaluator for \top-locality: Locality class obtained when concepts not present in the signature are given top concept interpretation, roles not present are universal role interpretation.

Method Summary

Modifier and Type	Method and Description
boolean	isLocal(OWLAxiom axiom, Collection<OWLEntity> signature) Tests whether the given axiom is local with respect to the given signature.
static SyntacticLocalityEvaluator	valueOf(String name) Returns the enum constant of this type with the specified name.
static SyntacticLocalityEvaluator[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

BOTTOM

public static final SyntacticLocalityEvaluator BOTTOM

The SyntacticLocalityEvaluator for \bottom-locality: Locality class obtained when concepts and roles not present in the signature are given empty interpretations. In the literature, $\emptyset$ for semantic and $\bottom$ for syntactic locality.

TOP

public static final SyntacticLocalityEvaluator TOP

The SyntacticLocalityEvaluator for \top-locality: Locality class obtained when concepts not present in the signature are given top concept interpretation, roles not present are universal role interpretation. In the literature, $\Delta$ for semantic and $\top$ for syntactic locality.

Method Detail

values

public static SyntacticLocalityEvaluator[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (SyntacticLocalityEvaluator c : SyntacticLocalityEvaluator.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SyntacticLocalityEvaluator valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isLocal

public final boolean isLocal(OWLAxiom axiom,
                             Collection<OWLEntity> signature)

Description copied from interface: LocalityEvaluator

Tests whether the given axiom is local with respect to the given signature. For efficient computation, the given collection should run Collection.contains(Object) in O(1).

Specified by:

isLocal in interface LocalityEvaluator

Parameters:

axiom - the axiom to test

signature - the signature to test against

Returns:

true if the axiom is local w.r.t. the signature; false otherwise
