PROPERTY_API int ATTRMAP_init_module

PROPERTY_API int ATTRMAP_list_all_mappings	(	int *	num_mappings,
		tag_t **	mappings
	)

Parameters

num_mappings	(O)
mappings	(OF) num_mappings

PROPERTY_API int ATTRMAP_list_mappings	(	tag_t	obj,
		tag_t	dataset_type,
		tag_t	item_type,
		logical	exact,
		int *	num_mappings,
		tag_t **	mappings
	)

If "exact" is true, we only pick up the mappings for exactly the supplied (or deduced) dataset-type/item-type combination. If it's false, then we also pick up the relevant more general mappings (e.g. the global ones).

Parameters

obj	(I)
dataset_type	(I)
item_type	(I)
exact	(I)
num_mappings	(O)
mappings	(OF) num_mappings

PROPERTY_API int ATTRMAP_refresh_mappings

PROPERTY_API int ATTRMAP_resolve_mapping	(	tag_t	obj,
		tag_t	mapping,
		ATTRMAP_mapping_type_t *	type,
		tag_t *	obj_to_lock,
		tag_t *	actual_property
	)

Normally, "obj_to_lock" is the object to which "actual_property" is attached; the one current exception is when the property is on a Form's data-file, when locking the data-file itself isn't enough to persuade the property to admit to being read-write - you have to lock the Form instead!

Parameters

obj	(I)
mapping	(I)
type	(O)
obj_to_lock	(O)
actual_property	(O)

PROPERTY_API int ATTRMAP_resolve_mapping_with_ir	(	tag_t	obj,
		tag_t	mapping,
		tag_t	itemRevTag,
		ATTRMAP_mapping_type_t *	type,
		tag_t *	obj_to_lock,
		tag_t *	actual_property
	)

Parameters

obj	(I)
mapping	(I)
itemRevTag	(I)
type	(O)
obj_to_lock	(O)
actual_property	(O)

PROPERTY_API int ATTRMAP_resolve_mappings	(	tag_t	obj,
		tag_t *	mappings,
		int	mappings_count,
		ATTRMAP_mapping_type_t **	types,
		tag_t **	objs_to_lock,
		tag_t **	actual_properties,
		int **	xref
	)

ATTRMAP_resolve_mappings does the same job as ATTRMAP_resolve_mapping, except on an array of mappings instead of just one mapping. It returns 4 result arrays. The first three are arrays of the same return values you would get from ATTRMAP_resolve_mapping. They are not in the same order, however, as the input array of mappings. Instead they are sorted by "objs_to_lock". This allows the caller to be more efficient in refreshing and locking when there are multiple poperties on the same object that have been mapped. The 4th array (xref) is the index into the input mappings array of the corresponding result. This allows the caller to easily match the results arrays to the input mappings array.

This function itself is generally more efficient than multiple calls to ATTRMAP_resolve_mapping. If there are many mappings that refer to attributes on the same object, the savings can be quite large.

Parameters

obj	(I)
mappings	(I)
mappings_count	(I)
types	(OF)
objs_to_lock	(OF)
actual_properties	(OF)
xref	(OF)
