- 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>
Decorates another
NavigableSet
to validate that all additions
match a specified predicate.
This set exists to provide validation for the decorated set. It is normally created to decorate an empty set. If an object cannot be added to the set, an IllegalArgumentException is thrown.
One usage would be to ensure that no null entries are added to the set.
NavigableSet set = PredicatedSortedSet.predicatedNavigableSet(new TreeSet(), NotNullPredicate.notNullPredicate());
