@GwtCompatible public abstract class ForwardingList<E> extends ForwardingCollection<E> implements java.util.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
net.lax1dude.eaglercraft.v1_8.RandomAccess
. If the delegate supports random access, theForwardingList
subclass should implement theRandomAccess
interface.Warning: The methods of
ForwardingList
forward indiscriminately to the methods of the delegate. For example, overridingadd(int, E)
alone will not change the behavior ofaddAll(int, java.util.Collection<? extends E>)
, which can lead to unexpected behavior. In this case, you should overrideaddAll
as well, either providing your own implementation, or delegating to the providedstandardAddAll
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.- Since:

Method Detail
-
delegate
protected abstract java.util.List<E> delegate()
Description copied from class:ForwardingObject
Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such asForwardingSet.delegate()
. Concrete subclasses override this method to supply the instance being decorated.- Specified by:

standardAdd
protected boolean standardAdd(E element)
A sensible default implementation ofForwardingCollection.add(Object)

-
standardIndexOf
protected int standardIndexOf(@Nullable java.lang.Object element)
