| org.apache.commons.collections.bag |
|
This package contains implementations of the
{@link org.apache.commons.collections.Bag Bag} and
{@link org.apache.commons.collections.SortedBag SortedBag} interfaces.
A bag stores an object and a count of the number of occurences of the object.
The following implementations are provided in the package:
- HashBag - implementation that uses a HashMap to store the data
- TreeBag - implementation that uses a TreeMap to store the data
The following decorators are provided in the package:
- Synchronized - synchronizes method access for multi-threaded environments
- Unmodifiable - ensures the bag cannot be altered
- Predicated - ensures that only elements that are valid according to a predicate can be added
- Typed - ensures that only elements that are of a specific type can be added
- Transformed - transforms each element added to the bag

| AbstractBagDecorator.java | Class | Decorates another Bag to provide additional behaviour. |
| AbstractMapBag.java | Class | Abstract implementation of the
Bag interface to simplify the creation
of subclass implementations.
Subclasses specify a Map implementation to use as the internal storage.
The map will be used to map bag elements to a number; the number represents
the number of occurrences of that element in the bag.

| AbstractSortedBagDecorator.java | Class | Decorates another SortedBag to provide additional behaviour. |
| AbstractTestBag.java | Class | Abstract test class for
org.apache.commons.collections.Bag Bag methods and contracts.
To use, simply extend this class, and implement
the
AbstractTestBag.makeBag method.
If your bag fails one of these tests by design,
you may still use this base set of cases. |
