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

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.

Implemented in moab::SparseTag, moab::VarLenSparseTag, moab::VarLenDenseTag, moab::DenseTag, moab::BitTag, and moab::MeshTag.

Returns:

MB_VARIABLE_LENGTH_DATA If variable_length() && lengths is NULL MB_INVALID_SIZE If variable_length() && lengths is not NULL && any size is not a multiple of type size. MB_INVALID_SIZE If !variable_length() && lengths is not NULL && any size is not the tag size. MB_SUCCESS Otherwise.
