public class CharRBTreeSet extends AbstractCharSortedSet implements Serializable, Cloneable, CharSortedSet
The iterators provided by this class are type-specific bidirectional iterators.
Moreover, the iterator returned by iterator() can be safely cast
to a type-specific list iterator.

AbstractCharCollectionThis implementation always throws an UnsupportedOperationException.
add in interface CharCollectionadd in class AbstractCharCollectionCollection.add(Object)public boolean remove(char k)
AbstractCharSetNote that the corresponding method of a type-specific collection is rem().
This unfortunate situation is caused by the clash
with the similarly named index-based method in the List interface.
Delegates to the type-specific rem() method
implemented by type-specific abstract Collection superclass.
remove in interface CharSetremove in class AbstractCharSetCollection.remove(Object)public boolean contains(char k)
AbstractCharCollectiontrue if this collection contains the specified element.
This implementation iterates over the elements in the collection, looking for the specified element.

Iterable.iterator(), which was already
strengthened in the corresponding type-specific class,
but was weakened by the fact that this interface extends Collection.

CharSortedSetBidirectionalIterator on the elements in
this set, starting from a given element of the domain (optional operation).
This method returns a type-specific bidirectional iterator with given
starting point. The starting point is any element comparable to the
elements of this set (even if it does not actually belong to the
set). The next element of the returned iterator is the least element of
the set that is greater than the starting point (if there are no
elements greater than the starting point, hasNext() will return
false). The previous element of the returned iterator is
the greatest element of the set that is smaller than or equal to the
starting point (if there are no elements smaller than or equal to the
starting point, hasPrevious() will return false).
Note that passing the last element of the set as starting point and
calling previous() you can traverse the
entire set in reverse order.
