Class CompositeList<T>

  • Type Parameters:
    T - Element type
    All Implemented Interfaces:
    java.lang.Iterable<T>, java.util.Collection<T>, java.util.List<T>
    public class CompositeList<T>
extends java.util.AbstractList<T>
    Read-only list that is the concatenation of sub-lists.

    The list is read-only; attempts to call methods such as AbstractList.add(Object) or AbstractList.set(int, Object) will throw.

    Changes to the backing lists, including changes in length, will be reflected in this list.

    This class is not thread-safe. Changes to backing lists will cause unspecified behavior.
