Inheritance diagram for itk::SmartPointer< TObjectType >:

Detailed Description

template<class TObjectType>
class itk::SmartPointer< TObjectType >

Implements transparent reference counting.

SmartPointer 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.

To compile / test this class Windows: cl SmartPointerTest.cxx; .\SmartPointerTest.exe linux: c++ SmartPointerTest.cxx ./a.out other: CCcompiler SmartPointerTest.cxx ./a.out
