Class FixedSizeList<E>

java.lang.Object
  org.apache.commons.collections.collection.AbstractCollectionDecorator<E>
      org.apache.commons.collections.list.AbstractListDecorator<E>
          org.apache.commons.collections.list.AbstractSerializableListDecorator<E>
              org.apache.commons.collections.list.FixedSizeList<E>

All Implemented Interfaces:

Serializable, Iterable<E>, Collection<E>, List<E>, BoundedCollection<E>

public class FixedSizeList<E>
extends AbstractSerializableListDecorator<E>
implements BoundedCollection<E>

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
