Class TreeBag
- Bag, Collection, Serializable, Bag, SortedBag
Implements
SortedBag
, using a
TreeMap
to provide
the data storage. This is the standard implementation of a sorted bag.
Order will be maintained among the bag members and can be viewed through the
iterator.
A
Bag
stores each object in the collection together with a
count of occurrences. Extra methods on the interface allow multiple copies
of an object to be added or removed at once. It is important to read the
interface javadoc carefully as several methods violate the
Collection
interface specification.
