public class LongRBTreeSet extends AbstractLongSortedSet implements Serializable, Cloneable, LongSortedSet
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.

AbstractLongCollection
This implementation always throws an
UnsupportedOperationException.
add in interface LongCollectionadd in class AbstractLongCollectionCollection.add(Object)public boolean remove(long k)
AbstractLongSet
Note 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 LongSetremove in class AbstractLongSetCollection.remove(Object)public boolean contains(long k)
AbstractLongCollectiontrue if this collection contains the specified element.
This implementation iterates over the elements in the collection, looking for the specified element.
contains in interface LongCollectioncontains in class AbstractLongCollectionCollection.contains(Object)public void clear()
java.util.AbstractCollectionThis implementation iterates over this collection, removing each element using the Iterator.remove operation. Most implementations will probably choose to override this method for efficiency.
Note that this implementation will throw an UnsupportedOperationException if the iterator returned by this collection's iterator method does not implement the remove method and this collection is non-empty.

LongSortedSetBidirectionalIterator 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.

This method performs a deep copy of this tree set; the data stored in the set, however, is not cloned. Note that this makes a difference only for object keys.
