// for objects held by the vtkSmartPointerBase superclass.

// Description:
// Transfer ownership of one reference to the given VTK object to a
// new smart pointer. The returned smart pointer does not increment
// the reference count of the object on construction but will
// decrement it on destruction. The caller is effectively passing
// ownership of one reference to the smart pointer. This is useful
// for code like:
//
// vtkSmartPointer<vtkFoo> foo =

// Work-around for HP and IBM overload resolution bug. Since
// NullPointerOnly is a private type the only pointer value that can
// be passed by user code is a null pointer. This operator will be
// chosen by the compiler when comparing against null explicitly and
// avoid the bogus ambiguous overload error.
