Util::Proxy< TYPE > Class Template Reference
#include <proxy.h>
Detailed Description
template<class TYPE>
class Util::Proxy< TYPE >
A Proxy holds an embedded object of any class and offers compare operators which are routed to the target object. Several Proxies may point to the same target object, a refcount is associated with the target object, and it will automatically be destroyed when all Proxies have gone. Proxies are useful in some situations when working with container classes, since they guarantee that the target object doesn't move in memory even when the proxy itself is moved around by the container class.(C) 2007 Radon Labs GmbH

Constructor & Destructor Documentation
template<class TYPE>
| Util::Proxy< TYPE >::Proxy | ( | const TYPE & | rhs | ) | [inline, explicit] |
construct from type
Constructing a proxy from TYPE always creates a new target object.
template<class TYPE>
| Util::Proxy< TYPE >::Proxy | ( | const Proxy< TYPE > & | rhs | ) | [inline, explicit] |
copy constructor
Constructing a proxy from another proxy shares the target object of the right-hand-side proxy and increments its refcount.
Member Function Documentation
template<class TYPE>
| void Util::Proxy< TYPE >::operator= | ( | const TYPE & | rhs | ) | [inline] |
assignment operator from type
Assigning a TYPE to the proxy will throw away the previous target object and create a new one.
template<class TYPE>
| void Util::Proxy< TYPE >::operator= | ( | const Proxy< TYPE > & | rhs | ) | [inline] |
assignment operator from proxy
Assigning a proxy to this proxy will share the right-hand-side's target object and incremnet its refcount.
