Member Function Documentation

◆ operator=() [1/4]

template<class T >

vtkSmartPointer & vtkSmartPointer< T >::operator= ( const vtkSmartPointer< T > & r )

inline

Assign object to reference.

This removes any reference to an old object.

Definition at line 251 of file vtkSmartPointer.h.

◆ operator=() [2/4]

template<class T >

template<class U >

vtkSmartPointer & vtkSmartPointer< T >::operator= ( const vtkSmartPointer & r )

inline

Assign object to reference.

This removes any reference to an old object.

Definition at line 258 of file vtkSmartPointer.h.

◆ operator=() [3/4]

template<class T >

template<typename U >

vtkSmartPointer & vtkSmartPointer< T >::operator= ( const vtkNew & r )

inline

Assign object to reference.

This removes any reference to an old object.

Definition at line 272 of file vtkSmartPointer.h.

◆ operator=() [4/4]

template<class T >

template<typename U >

vtkSmartPointer & vtkSmartPointer< T >::operator= ( U * r )

inline

Assign object to reference.

This adds a new reference to an old object.

Definition at line 285 of file vtkSmartPointer.h.

◆ GetPointer()

template<class T >

T * vtkSmartPointer< T >::GetPointer ( ) const

inlinenoexcept

Get the contained pointer.

Definition at line 297 of file vtkSmartPointer.h.

◆ Get()

template<class T >

T * vtkSmartPointer< T >::Get ( ) const

inlinenoexcept

Get the contained pointer.

Definition at line 298 of file vtkSmartPointer.h.

◆ operator T*()

template<class T >

vtkSmartPointer< T >::operator T* ( ) const

inlinenoexcept

Get the contained pointer.

Definition at line 304 of file vtkSmartPointer.h.

◆ operator*()

template<class T >

T & vtkSmartPointer< T >::operator* ( ) const

inlinenoexcept

Dereference the pointer and return a reference to the contained object.

Definition at line 310 of file vtkSmartPointer.h.

◆ operator->()

template<class T >

T * vtkSmartPointer< T >::operator-> ( ) const

inlinenoexcept

Provides normal pointer target member access using operator ->.

Definition at line 315 of file vtkSmartPointer.h.

◆ TakeReference()

template<class T >

void vtkSmartPointer< T >::TakeReference ( T * t )

inline

Transfer ownership of one reference to the given VTK object to this smart pointer.

This does not increment the reference count of the object, but will decrement it later. The caller is effectively passing ownership of one reference to the smart pointer. This is useful for code like:

vtkSmartPointer<vtkFoo> foo; foo.TakeReference(bar->NewFoo());

The input argument may not be another smart pointer.

Definition at line 329 of file vtkSmartPointer.h.

◆ New()

template<class T >

static vtkSmartPointer< T > vtkSmartPointer< T >::New ( )

inlinestatic

Create an instance of a VTK object.

Definition at line 334 of file vtkSmartPointer.h.

◆ ExtendedNew()

template<class T >

static vtkSmartPointer< T > vtkSmartPointer< T >::ExtendedNew ( )

inlinestatic

Create an instance of a VTK object in a memkind extended memory space.

Note that not all vtkObjects support this yet and that VTK needs to be compiled with VTK_USE_MEMKIND to enable those that do. If not enabled, this is equivalent to calling New()

Definition at line 340 of file vtkSmartPointer.h.

◆ NewInstance()

template<class T >

static vtkSmartPointer< T > vtkSmartPointer< T >::NewInstance ( T * t )

inlinestatic

Create a new instance of the given VTK object.

Definition at line 348 of file vtkSmartPointer.h.

◆ Take()

template<class T >

static vtkSmartPointer< T > vtkSmartPointer< T >::Take ( T * t )

inlinestatic

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 = vtkSmartPointer<vtkFoo>::Take(bar->NewFoo());

The input argument may not be another smart pointer.
