| /** |
| * Implements the {@link java.util.Set Set}, |
| * {@link java.util.SortedSet SortedSet} and |
| * {@link java.util.NavigableSet NavigableSet} interfaces. |
| * <p> |
| * The implementations are in the form of direct implementations and decorators. |
| * A decorator wraps another implementation of the interface to add some |
| * specific additional functionality. |
| * <p> |
| * The following implementations are provided in the package: |
| * <ul> |
| * <li>CompositeSet - a set that combines multiple sets into one |
| * </ul> |
| * The following decorators are provided in the package: |
| * <ul> |
| * <li>Unmodifiable - ensures the collection cannot be altered |
| * <li>Predicated - ensures that only elements that are valid according to a predicate can be added |
| * <li>Transformed - transforms each element added |
| * <li>ListOrdered - ensures that insertion order is retained |
| * <li>MapBackedSet - a set formed by decorating a Map |
| * </ul> |
