Detailed Description

template<class T>
class itk::SmartPointerForwardReference< T >

Implements transparent reference counting in situations where forward references / cyclic include dependencies are a problem.

SmartPointerForwardReference implements reference counting by overloading operator -> (and *) among others. This allows natural interface to the class referred to by the pointer without having to invoke special Register()/UnRegister() methods directly.

This class is nearly identical to itkSmartPointer except that is used in situations where forward references or cyclic include dependencies become a problem. This class requires that the .h file is included in the .h file of the class using it, and the .hxx file is included in the .cxx/.hxx file of the class using it. (Make sure that SmartPointerForwardReference.hxx is included last in the .cxx/.hxx list of includes.)
