PropertyHandle :: GetCount - Get number of instances stored for property

The function returns the number of instances stored in the collection. Since some indexes store multiple references to instances (array index) or do not store all instances in the index, the function returns rather the number of references in the index than the number of instances in the collection. Usually these numbers are, however, identical. In order to ensure that the collection count refers to the total number of instances for the collection, one may select the default order ( SetOrder() ).
