Attribute DIMENSION_LIST update function.
This function exists to update DIMENSION_LISTs without updating the mirrored REFERENCE_LIST entry in the variable's scales. This is done for performance reasons, as attaching dimension scales for hundreds of variables sequentially is very slow.
NOTE: This code does not use the regular atts.open(...) call for performance reasons when we have to repeat this call for hundreds or thousands of variables. We instead do a creation-order-preferred search.
- Parameters
-
| var | is the variable of interest. |
| new_dim_list | is the mapping of dimensions that should be added to the variable. |

Attribute REFERENCE_LIST update function.

- Parameters
-
| scale | is the scale of interest. |
| ref_var_axis_list | is the mapping of variables-dimension numbers that should be added to the scale's REFERENCE_LIST attribute. |

) |
| |
Linear search to find and open an attribute, if it exists.
- Parameters
-
| baseObject | is the object that could contain the attribute. |
| objType | is the type of object (Dataset or Group). |
| attname | is the name of the attribute. |
- Returns
- An open handle to the attribute, if it exists.
-
An invalid handle if the attribute does not exist or upon general failure.
This function is useful because it is faster than the regular attribute open by name routine, which does not take advantage of attribute creation order indexing. Performance is particularly good when there are few attributes attached to the base object.
