Class AppendingList<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<E>

net.sf.mmm.util.collection.base.AppendingList<E>

Type Parameters:

E - is the generic type of the list elements.

All Implemented Interfaces:

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

public class AppendingList<E>
extends AbstractList<E>

This is an implementation of the List interface that gives a read-only view on other lists that appear as if they were concatenated.
ATTENTION:
This implementation is NOT thread-safe. It may cause problems if a method is called while one of the concatenated sub-lists is modified.
