Detailed Description

template<class T, class Cloner>
class ProxyBase< T, Cloner >

A base class for reference counting proxies. The class to which this one is proxy must inherit from ReferenceCounted. A ProxyBase has value semantics, in contrast to ReferenceCountingPointer, which has pointer semantics. The Proxy class inheriting from ProxyBase must duplicate the part of the interface of the reference counted class that it whiches to expose.
