AbstractSortedSetDecorator (Apache Commons Collections 4.2 API)

java.lang.Object
- org.apache.commons.collections4.collection.AbstractCollectionDecorator<E>
- - org.apache.commons.collections4.set.AbstractSetDecorator<E>
  - - org.apache.commons.collections4.set.AbstractSortedSetDecorator<E>

Type Parameters:

E - the type of the elements in the sorted set

All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, Set<E>, SortedSet<E>

Direct Known Subclasses:

AbstractNavigableSetDecorator, UnmodifiableSortedSet
```
public abstract class AbstractSortedSetDecorator<E>
extends AbstractSetDecorator<E>
implements SortedSet<E>
```
Decorates another SortedSet to provide additional behaviour.
Methods are forwarded directly to the decorated set.

Since:

3.0
