org.apache.commons.collections4.set.UnmodifiableNavigableSet<E>

Type Parameters:: E - the type of the elements in this set

All Implemented Interfaces:: Serializable, Iterable<E>, Collection<E>, NavigableSet<E>, Set<E>, SortedSet<E>, Unmodifiable

public final class UnmodifiableNavigableSet<E> extends AbstractNavigableSetDecorator<E> implements Unmodifiable

Decorates another NavigableSet to ensure it can't be altered.

Attempts to modify it will result in an UnsupportedOperationException.
