Class PredicatedList<E>
java.lang.Object
org.apache.commons.collections4.collection.AbstractCollectionDecorator<E>
org.apache.commons.collections4.collection.PredicatedCollection<E>
org.apache.commons.collections4.list.PredicatedList<E>
- Type Parameters:
- E- the type of the elements in the list.
- All Implemented Interfaces:
- Serializable,- Iterable<E>,- Collection<E>,- List<E>
Decorates another 
List to validate that all additions
 match a specified predicate.
 This list exists to provide validation for the decorated list. It is normally created to decorate an empty list. If an object cannot be added to the list, an IllegalArgumentException is thrown.
One usage would be to ensure that no null entries are added to the list.
 
 List<String> list =
   PredicatedList.predicatedList(new ArrayList<String>(), PredicateUtils.notNullPredicate());
 
 
 This class is Serializable from Commons Collections 3.1.
