5.3.7. The Bag Class

A bag is a non-sparse collection that restricts the elements to having an item that is the same as the index. Any object can be placed in a bag, and the same object can be placed in a bag several times.

Note

The Bag class also has available class methods that its metaclass, the Class class (Section 5.1.2, “The Class Class”), defines. It also inherits methods from the Set Collection (Section 5.3.5, “The SetCollection Class”) class, although there are not currently any methods defined in that class.

The Bag class is a subclass of the Relation class. In addition to its own methods, it inherits the methods of the Object class and the Relation class.
