Class	Description
LazyRef<T>	A supplier for a ref backed by a root ref.
RefDelegateBase<T,R extends Ref<T>>
RefFutureImpl<T>
RefImpl<T>	Implementation of a Ref TODO Avoid needless synchronization; a ConcurrentHashMap may help; ref.equals could do only reference comparison
ResourceHolderImpl<T>	Associate a resource with a closing mechanism
SingletonLazyRef<T>	A wrapper that turns a supplier of references into a singleton such that at any given time (on a specific jvm) only a most a single reference will have been acquired from that supplier.
