Allocate and hold a VTK object.
void Reset()
Deletes reference to instance of T.
T * Get() const noexcept
Get a raw pointer to the contained object.
vtkNew()
Create a new T on construction.
T * operator->() const noexcept
Enable pointer-like dereference syntax.
vtkNew(vtkNew &&o) noexcept
Move the object into the constructed vtkNew wrapper, stealing its reference.
~vtkNew()
Deletes reference to instance of T.
vtkNew(vtkNew< U > &&o) noexcept
Move the object into the constructed vtkNew wrapper, stealing its reference.
T * GetPointer() const noexcept
Get a raw pointer to the contained object.
T & operator*() const noexcept
Dereference the pointer and return a reference to the contained object.
vtkNew< T > & operator=(vtkNew< T > &&other) noexcept
Move assignment operator.
abstract base class for most VTK objects
Hold a reference to a vtkObjectBase instance.
a weak reference to a vtkObject.
