Detailed Description

template<class TObjectType>
class mitk::WeakPointer< TObjectType >

Implements a weak reference to an object.

Extends the standard itk WeakPointer by listening to delete events of itk::Objects. When an itk::Object is deleted the WeakPointer sets its internal Pointer to 0. This enables checking against 0 and avoids crashes by accessing changed memory. Furthermore it dispatches Modified events with the mitkMessageDelegate system which is much easier to use.
