Class ForwardingCollection<E>

All Implemented Interfaces:
Iterable<E>, Collection<E>
Direct Known Subclasses:

public abstract class ForwardingCollection<E> extends Object implements Collection<E>
A collection which forwards all its method calls to another collection. Subclasses should override one or more methods to modify the behavior of the backing collection as desired per the decorator pattern.

Warning: The methods of ForwardingCollection forward indiscriminately to the methods of the delegate. For example, overriding add(E) alone will not change the behavior of addAll(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 are not guaranteed to be thread-safe, even when all of the methods that they depend on are thread-safe.
