Gets all entity handles that match a type and tag.

Count the entities for which the a tag value has been set, or a close approximation if the tag storage scheme cannot accurately determine exactly which entities have explicit values.

Parameters

seqman	Pointer to entity storage database
output_count	This is incremented for each detected entity.
type	Optional entity type. If specified, search is limited to entities of specified type.
intersect	Optional intersect list. If specified, search is restricted to entities in this list.

Implements moab::TagInfo.

◆ release_all_data()

ErrorCode moab::SparseTag::release_all_data	(	SequenceManager *	seqman,

virtual

Remove/clear tag data for all entities.

Remove tag values from entities.

Parameters

delete_pending If true, then release any global data associated with the tag in preparation for deleting the tag itself.

Note: Invalidates tag if tag_delete_pending is true. The only valid method that can be invoked that is is the destructor.

Parameters

		bool	allocate = `true`
	)

virtual

Access tag data via direct pointer into contiguous blocks.

Iteratively obtain direct access to contiguous blocks of tag storage. This function cannot be used with bit tags because of the compressed bit storage. This function cannot be used with variable length tags because it does not provide a mechanism to determine the length of the value for each entity. This function may be used with sparse tags, but if it is used, it will return data for a single entity at a time.

Parameters

iter	As input, the first entity for which to return data. As output, one past the last entity for which data was returned.
end	One past the last entity for which data is desired
data_ptr	Output: pointer to tag storage.
allocate	If true, space for this tag will be allocated, if not it wont

Note: If this function is called for entities for which no tag value has been set, but for which a default value exists, it will force the allocation of explicit storage for each such entity even though MOAB would normally not explicitly store tag values for such entities.
