5.71 GetAttrVals

procedure GetAttrVals(
  o: DSName,
  att: ATTRTYP,
  includeDeletedLinks: boolean): set of attribute value

The GetAttrVals procedure constructs a set V that contains each value of the attribute att from object o.

If att is not a link attribute, the value of includeDeletedLinks is ignored. If att is a link attribute and includeDeletedLinks = false, the set includes only those values v of att such that LinkStamp(o, att, v).timeDeleted = 0. If att is a link attribute and includeDeletedLinks = true, the set contains all values v of att, even those such that LinkStamp(o, att, v).timeDeleted ≠ 0.

If the V is empty, null is returned. Otherwise, V is returned.
