All Implemented Interfaces:

Iterable<E>, Collection<E>, List<E>

Direct Known Subclasses:

TransformedList

public abstract class CollectionAsList<E>
extends AbstractList<E>

Delegates all collection calls to another collection. Useful base class for list wrappers. Note that this class differs from other upgrading wrappers in three respects:

1. It is abstract.
2. It does not inherit from CollectionProxy but from a skeleton implementation.
3. It has a brother class CollectionAsSequentialList.
