Detailed Description
template<class TObjectType>
class itk::WeakPointer< TObjectType >
Implements a weak reference to an object.
WeakPointer implements a weak reference to an object. A natural interface to the class is defined by operator -> (and *) among others. WeakPointer is really nothing more than a standard pointer. It is used to call attention to the fact that it does not adjust the reference count of an object like SmartPointer does. WeakPointer is used internally to Insight to manage (break) reference counting loops. At some point, an object may keep track of how many objects hold weak references to itself. In all cases, however, an outstanding weak reference will not keep an object from destructing.
