Data Subproperties

struct CowlSubDataPropAxiom : public CowlAxiom

Represents a SubDataPropertyOf axiom in the OWL 2 specification.

Public Static Functions

static inline CowlSubDataPropAxiom *cowl_sub_data_prop_axiom(CowlAnyDataPropExp *sub, CowlAnyDataPropExp *super, CowlVector *annot)

Returns a retained data subproperty axiom.

Parameters

  • sub – The subproperty.

  • super – The superproperty.

  • annot – [optional] The annotations.

Returns

Retained axiom, or NULL on error.

static inline CowlSubDataPropAxiom *cowl_sub_data_prop_axiom_retain(CowlSubDataPropAxiom *axiom)

Retains the specified axiom.

Parameters

axiom – The axiom.

Returns

Retained axiom.

static inline void cowl_sub_data_prop_axiom_release(CowlSubDataPropAxiom *axiom)

Releases the specified axiom.

Parameters

axiom – The axiom.

static inline CowlDataPropExp *cowl_sub_data_prop_axiom_get_sub(CowlSubDataPropAxiom *axiom)

Gets the subproperty.

Parameters

axiom – The axiom.

Returns

The subproperty.

static inline CowlDataPropExp *cowl_sub_data_prop_axiom_get_super(CowlSubDataPropAxiom *axiom)

Gets the superproperty.

Parameters

axiom – The axiom.

Returns

The superproperty.

static inline CowlVector *cowl_sub_data_prop_axiom_get_annot(CowlSubDataPropAxiom *axiom)

Gets the annotations of the specified axiom.

Parameters

axiom – The axiom.

Returns

The annotations.

static inline CowlString *cowl_sub_data_prop_axiom_to_string(CowlSubDataPropAxiom *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_sub_data_prop_axiom_equals(CowlSubDataPropAxiom *lhs, CowlSubDataPropAxiom *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_sub_data_prop_axiom_hash(CowlSubDataPropAxiom *axiom)

Hash function.

Parameters

axiom – The axiom.

Returns

The hash value.

static inline bool cowl_sub_data_prop_axiom_iterate_primitives(CowlSubDataPropAxiom *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.
