Class CompositeList<T>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<T>

org.apache.calcite.util.CompositeList<T>

Type Parameters:

T - Element type

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>

public class CompositeList<T>
extends 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.
