ForwardingSet
protected ForwardingSet(Set<E> delegate)
- Constructs a forwarding set that forwards to the provided delegate.
delegate
protected Set<E> delegate()
- Description copied from class:
ForwardingObject
- Returns the backing delegate object. This method should be overridden to
specify the correct return type. For example:
@SuppressWarnings("unchecked")
@Override protected Foo delegate() {
return (Foo) super.delegate();
}
This method should always return the same delegate instance that was passed
to the constructor.
