All Implemented Interfaces:

java.io.Serializable, java.lang.Iterable, java.util.Collection, java.util.List, BoundedCollection

public class FixedSizeList
extends AbstractSerializableListDecorator
implements BoundedCollection

Decorates another List to fix the size preventing add/remove.

The add, remove, clear and retain operations are unsupported. The set method is allowed (as it doesn't change the list size).

This class is Serializable from Commons Collections 3.1.

Since:

Commons Collections 3.0
