Object Property Expressions

struct CowlObjPropExp : public CowlObject

Represents an ObjectPropertyExpression in the OWL 2 specification.

Subclassed by CowlInvObjProp, CowlObjProp

Public Functions

CowlObjProp *cowl_obj_prop_exp_get_prop(CowlAnyObjPropExp *exp)

Gets the underlying object property.

Parameters

exp – The object property expression.

Returns

The object property.

Public Static Functions

static inline CowlAnyObjPropExp *cowl_obj_prop_exp_retain(CowlAnyObjPropExp *exp)

Retains the specified object property expression.

Parameters

exp – The object property expression.

Returns

Retained object property expression.

static inline void cowl_obj_prop_exp_release(CowlAnyObjPropExp *exp)

Releases the specified object property expression.

Parameters

exp – The object property expression.

static inline bool cowl_obj_prop_exp_is_inverse(CowlAnyObjPropExp *exp)

Returns true if the object property expression is inverse.

Parameters

exp – The object property expression.

Returns

True if the expression is inverse, false otherwise.

static inline CowlString *cowl_obj_prop_exp_to_string(CowlAnyObjPropExp *exp)

Returns the string representation of the specified object property expression.

Note

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

Parameters

exp – The object property expression.

Returns

String representation, or NULL on error.

static inline bool cowl_obj_prop_exp_equals(CowlAnyObjPropExp *lhs, CowlAnyObjPropExp *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_obj_prop_exp_hash(CowlAnyObjPropExp *exp)

Hash function.

Parameters

exp – The object property expression.

Returns

The hash value.

static inline bool cowl_obj_prop_exp_iterate_primitives(CowlAnyObjPropExp *exp, CowlPrimitiveFlags flags, CowlIterator *iter)

Iterates over the primitives referenced by the specified object property expression.

Parameters

  • exp – The object property expression.

  • flags – Iteration flags.

  • iter – The iterator.

Returns

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