Class ForwardingList<E extends @Nullable Object>

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>, SequencedCollection<E>
@GwtCompatible public abstract class ForwardingList<E extends @Nullable Object> 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.

default method warning: This class does not forward calls to default methods. Instead, it inherits their default implementations. When those implementations invoke methods, they invoke methods on the ForwardingList.

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.
