E - the type of the elements in this setpublic class PredicatedSortedSet<E> extends PredicatedSet<E> implements SortedSet<E>
SortedSet 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.
SortedSet set =
PredicatedSortedSet.predicatedSortedSet(new TreeSet(),
NotNullPredicate.notNullPredicate());
This class is Serializable from Commons Collections 3.1.
