# Class FixedSizeList<E>

java.lang.Object
org.apache.commons.collections4.collection.AbstractCollectionDecorator<E>
org.apache.commons.collections4.list.AbstractListDecorator<E>
org.apache.commons.collections4.list.AbstractSerializableListDecorator<E>
org.apache.commons.collections4.list.FixedSizeList<E>

Type Parameters:
  `E` - the type of elements in this collection

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).

NOTE: Modifying the decorated list directly would results in influencing the outcome of method calls on this object. For example, the bounds of this list would reflect a newly added object to the underlying list.

This class is Serializable from Commons Collections 3.1.

Since:
  3.0
