Class PredicatedSortedSet

All Implemented Interfaces:
Serializable, Iterable, Collection, Set, SortedSet

public class PredicatedSortedSet extends PredicatedSet implements SortedSet
Decorates another 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.decorate(new TreeSet(), NotNullPredicate.INSTANCE);

This class is Serializable from Commons Collections 3.1.

      Constructor that wraps (not copies).

      If there are any elements already in the set being decorated, they are validated.

      Parameters:
      set - the set to decorate, must not be null
      predicate - the predicate to use for validation, must not be null
      Throws:
      IllegalArgumentException - if set or predicate is null
      IllegalArgumentException - if the set contains invalid elements
