abstract base class for most VTK objects
Non-templated superclass for vtkWeakPointer.
vtkWeakPointerBase(const vtkWeakPointerBase &r)
Copy r's data object into the new weak pointer.
vtkWeakPointerBase(vtkObjectBase *r)
Initialize smart pointer to given object.
~vtkWeakPointerBase()
Destroy smart pointer.
vtkObjectBase * GetPointer() const
Get the contained pointer.
vtkWeakPointerBase(vtkWeakPointerBase &&r) noexcept
Move r's object into the new weak pointer, setting r to nullptr.
vtkWeakPointerBase & operator=(vtkObjectBase *r)
Assign object to reference.
vtkWeakPointerBase(vtkObjectBase *r, const NoReference &)
vtkWeakPointerBase & operator=(const vtkWeakPointerBase &r)
Assign object to reference.
vtkWeakPointerBase & operator=(vtkWeakPointerBase &&r) noexcept
Assign object to reference.
vtkWeakPointerBase() noexcept
Initialize smart pointer to nullptr.
VTKCOMMONCORE_EXPORT ostream & operator<<(ostream &os, const vtkWeakPointerBase &p)
Compare smart pointer values.
