Class ForwardingList<E>

java.lang.Object

com.google.common.collect.ForwardingObject

com.google.common.collect.ForwardingCollection<E>

com.google.common.collect.ForwardingList<E>

All Implemented Interfaces:

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

@GwtCompatible
public abstract class ForwardingList<E>
extends ForwardingCollection<E>
implements List<E>

A list which forwards all its method calls to another list. Subclasses should override one or more methods to modify the behavior of the backing list as desired per the decorator pattern.

This class does not implement RandomAccess. If the delegate supports random access, the ForwardingList subclass should implement the RandomAccess interface.

Warning: The methods of ForwardingList forward indiscriminately to the methods of the delegate. For example, overriding add(int, E) alone will not change the behavior of addAll(int, java.util.Collection<? extends E>), which can lead to unexpected behavior. In this case, you should override addAll as well, either providing your own implementation, or delegating to the provided standardAddAll method.

The standard methods and any collection views they return are not guaranteed to be thread-safe, even when all of the methods that they depend on are thread-safe.
