@GwtIncompatible public abstract class ForwardingNavigableSet<E> extends ForwardingSortedSet<E> implements NavigableSet<E>
Warning: The methods of ForwardingNavigableSet
forward indiscriminately
to the methods of the delegate. For example, overriding ForwardingCollection.add(E)
alone will not change
the behavior of ForwardingCollection.addAll(java.util.Collection<? extends E>)
, which can lead to unexpected behavior. In this case, you should
override addAll
as well, either providing your own implementation, or delegating to the
provided standardAddAll
method.
default
method warning: This class does not forward calls to default
methods. Instead, it inherits their default implementations. When those implementations
invoke methods, they invoke methods on the ForwardingNavigableSet
.
Each of the standard
methods uses the set's comparator (or the natural ordering of the
elements, if there is no comparator) to test element equality. As a result, if the comparator is
not consistent with equals, some of the standard implementations may violate the Set
contract.
The standard
methods and the collection views they return are not guaranteed to be
thread-safe, even when all of the methods that they depend on are thread-safe.
