| /** |
| * This package contains implementations of the |
| * {@link org.apache.commons.collections4.MultiSet MultiSet} and |
| * {@link org.apache.commons.collections4.SortedMultiSet SortedMultiSet} interfaces. |
| * A multiset stores an object and a count of the number of occurrences of the object. |
| * <p> |
| * The following implementations are provided in the package: |
| * <ul> |
| * <li>HashMultiSet - implementation that uses a HashMap to store the data |
| * <li>TreeMultiSet - implementation that uses a TreeMap to store the data |
| * </ul> |
| * <p> |
| * The following decorators are provided in the package: |
| * <ul> |
| * <li>Predicated - ensures that only elements that are valid according to a predicate can be added |
| * <li>Synchronized - synchronizes method access for multi-threaded environments |
| * <li>Unmodifiable - ensures the multiset cannot be altered |
| * </ul> |
| * |
| * @version $Id$ |
