Defined in file: hzDocument.h

The hzAttrset class is really an convenient attribute iterator. The tag attributes are stored in the host document in a one-to-many map between tag uids and attribute, rather than in a list held by the host tag. Given this arrangement, iteration of tag attributes would normally require a first and a last position within the map, as well as another variable to iterate between the two. In previous version of the HadronZoo library, each tag had an attribute pointer and each attribute had a next pointer. Attributes could be iterated by control loops of the form:- for (attr = first_attr ; attr ; attr = attr->next) {} The objective of the attribute iterator is to achieve a similar interface. The hzAttrset is initialized to a tag (node) which in turn points to the host document. The initialization does a lookup in the document map and the Valid() method returns true if there is an attribute. The Advance() method moves on to the next attribut in the tag so:- for (attrset = node ; attrset.Valid() ; attrset.Advance()) {}
