Datatype Restrictions

struct CowlDatatypeRestr : public CowlDataRange

Represents a DatatypeRestriction in the OWL 2 specification.

Public Static Functions

static inline CowlDatatypeRestr *cowl_datatype_restr(CowlDatatype *datatype, CowlVector *restrictions)

Returns a retained datatype restriction.

Parameters

  • datatype – The datatype that this data range restricts.

  • restrictions – Set of facet restrictions.

Returns

Retained datatype restriction, or NULL on error.

static inline CowlDatatypeRestr *cowl_datatype_restr_retain(CowlDatatypeRestr *restr)

Retains the specified datatype restriction.

Parameters

restr – The restriction.

Returns

Retained datatype restriction.

static inline void cowl_datatype_restr_release(CowlDatatypeRestr *restr)

Releases the specified datatype restriction.

Parameters

restr – The datatype restriction.

static inline CowlDatatype *cowl_datatype_restr_get_datatype(CowlDatatypeRestr *restr)

Gets the datatype that this data range restricts.

Parameters

restr – The datatype restriction.

Returns

The datatype.

static inline CowlVector *cowl_datatype_restr_get_restrictions(CowlDatatypeRestr *restr)

Gets the facet restrictions.

Parameters

restr – The datatype restriction.

Returns

The facet restrictions.

static inline CowlString *cowl_datatype_restr_to_string(CowlDatatypeRestr *restr)

Returns the string representation of the specified datatype restriction.

Note

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

Parameters

restr – The datatype restriction.

Returns

String representation, or NULL on error.

static inline bool cowl_datatype_restr_equals(CowlDatatypeRestr *lhs, CowlDatatypeRestr *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_datatype_restr_hash(CowlDatatypeRestr *restr)

Hash function.

Parameters

restr – The datatype restriction.

Returns

The hash value.

static inline bool cowl_datatype_restr_iterate_primitives(CowlDatatypeRestr *restr, CowlPrimitiveFlags flags, CowlIterator *iter)

Iterates over the primitives referenced by the specified datatype restriction.

Parameters

  • restr – The datatype restriction.

  • flags – Iteration flags.

  • iter – The iterator.

Returns

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

struct CowlFacetRestr : public CowlObject

Represents a facet restriction used to restrict a particular CowlDatatype.
