net.sf.molae.pipe.basic.CollectionAsList<E>
- 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:
- It is abstract.
- It does not inherit from
CollectionProxy
but from a
skeleton implementation.
- It has a brother class
CollectionAsSequentialList
.
