@Deprecated(since="2021-04-30")
public class PredicatedList
extends PredicatedCollection
implements List

Deprecated.

Commons Collections 3 is in maintenance mode. Commons Collections 4 should be used instead.

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 list = PredicatedList.decorate(new ArrayList(), NotNullPredicate.INSTANCE);

This class is Serializable from Commons Collections 3.1.

Since:

Commons Collections 3.0

decorate

public static List decorate(List list,
                            Predicate predicate)

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

Parameters:

list - the list to decorate, must not be null

predicate - the predicate to use for validation, must not be null

Throws:

IllegalArgumentException - if list or predicate is null

IllegalArgumentException - if the list contains invalid elements
