Inverse Object Properties

struct CowlInvObjPropAxiom : public CowlAxiom

Represents an InverseObjectProperties axiom in the OWL 2 specification.

Public Static Functions

static inline CowlInvObjPropAxiom *cowl_inv_obj_prop_axiom(CowlAnyObjPropExp *first, CowlAnyObjPropExp *second, CowlVector *annot)

Returns a retained inverse object properties axiom.

Parameters

  • first – The first object property expression.

  • second – The second object property expression.

  • annot – [optional] The annotations.

Returns

Retained axiom, or NULL on error.

static inline CowlInvObjPropAxiom *cowl_inv_obj_prop_axiom_retain(CowlInvObjPropAxiom *axiom)

Retains the specified axiom.

Parameters

axiom – The axiom.

Returns

Retained axiom.

static inline void cowl_inv_obj_prop_axiom_release(CowlInvObjPropAxiom *axiom)

Releases the specified axiom.

Parameters

axiom – The axiom.

static inline CowlObjPropExp *cowl_inv_obj_prop_axiom_get_first_prop(CowlInvObjPropAxiom *axiom)

Gets the first of the two object property expressions.

Parameters

axiom – The axiom.

Returns

The first object property expression.

static inline CowlObjPropExp *cowl_inv_obj_prop_axiom_get_second_prop(CowlInvObjPropAxiom *axiom)

Gets the second of the two object property expressions.

Parameters

axiom – The axiom.

Returns

The second object property expression.

static inline CowlVector *cowl_inv_obj_prop_axiom_get_annot(CowlInvObjPropAxiom *axiom)

Gets the annotations of the specified axiom.

Parameters

axiom – The axiom.

Returns

The annotations.

static inline CowlString *cowl_inv_obj_prop_axiom_to_string(CowlInvObjPropAxiom *axiom)

Returns the string representation of the specified axiom.

Note

The returned string is retained, so you are responsible for releasing it.

Parameters

axiom – The axiom.

Returns

String representation, or NULL on error.

static inline bool cowl_inv_obj_prop_axiom_equals(CowlInvObjPropAxiom *lhs, CowlInvObjPropAxiom *rhs)

Equality function.

Parameters

  • lhs – LHS of the equality relation.

  • rhs – RHS of the equality relation.

Returns

True if the equality relation holds, false otherwise.

static inline ulib_uint cowl_inv_obj_prop_axiom_hash(CowlInvObjPropAxiom *axiom)

Hash function.

Parameters

axiom – The axiom.

Returns

The hash value.

static inline bool cowl_inv_obj_prop_axiom_iterate_primitives(CowlInvObjPropAxiom *axiom, CowlPrimitiveFlags flags, CowlIterator *iter)

Iterates over the primitives referenced by the specified axiom.

Parameters

  • axiom – The axiom.

  • flags – Iteration flags.

  • iter – The iterator.

Returns

True if the iteration was completed, false if it was stopped.
