Member Function Documentation

◆ getData()

template<typename Object >

template<typename Device = Devices::Host>

__cuda_callable__ const Object & TNL::Pointers::DevicePointer< Object, Devices::Host >::getData ( ) const

inline

Constant object reference getter.

No synchronization of this pointer will be performed due to calling this method.

Template Parameters

Device says what image of the object one want to dereference. It can be either DeviceType or Devices::Host.

Returns: constant reference to the object image on given device.

◆ modifyData()

template<typename Object >

template<typename Device = Devices::Host>

__cuda_callable__ Object & TNL::Pointers::DevicePointer< Object, Devices::Host >::modifyData ( )

inline

Non-constant object reference getter.

No synchronization of this pointer will be performed due to calling this method.

Template Parameters

Device says what image of the object one want to dereference. It can be either DeviceType or Devices::Host.

Returns: constant reference to the object image on given device.

◆ operator bool()

template<typename Object >

__cuda_callable__ TNL::Pointers::DevicePointer< Object, Devices::Host >::operator bool ( ) const

inline

Conversion to boolean type.

Returns: Returns true if the pointer is not empty, false otherwise.

◆ operator!()

template<typename Object >

__cuda_callable__ bool TNL::Pointers::DevicePointer< Object, Devices::Host >::operator! ( ) const

inline

Negation operator.

Returns: Returns false if the pointer is not empty, true otherwise.

◆ operator*() [1/2]

template<typename Object >

Object & TNL::Pointers::DevicePointer< Object, Devices::Host >::operator* ( )

inline

Dereferencing operator for accessing the object owned by non-constant smart pointer.

Returns: reference to the object owned by this smart pointer.

◆ operator*() [2/2]

template<typename Object >

const Object & TNL::Pointers::DevicePointer< Object, Devices::Host >::operator* ( ) const

inline

Dereferencing operator for accessing the object owned by constant smart pointer.

Returns: constant reference to the object owned by this smart pointer.

◆ operator->() [1/2]

template<typename Object >

Object * TNL::Pointers::DevicePointer< Object, Devices::Host >::operator-> ( )

inline

Arrow operator for accessing the object owned by non-constant smart pointer.

Returns: pointer to the object owned by this smart pointer.

◆ operator->() [2/2]

template<typename Object >

const Object * TNL::Pointers::DevicePointer< Object, Devices::Host >::operator-> ( ) const

inline

Arrow operator for accessing the object owned by constant smart pointer.

Returns: constant pointer to the object owned by this smart pointer.

◆ operator=() [1/4]

template<typename Object >

const DevicePointer & TNL::Pointers::DevicePointer< Object, Devices::Host >::operator= ( const DevicePointer< Object, Devices::Host > & ptr )

inline

Assignment operator.

It assigns object owned by the pointer ptr to this pointer.

Parameters

ptr	input pointer

Returns: constant reference to this

◆ operator=() [2/4]

template<typename Object >

template<typename Object_ , typename = Enabler< Object_ >>

const DevicePointer & TNL::Pointers::DevicePointer< Object, Devices::Host >::operator= ( const DevicePointer< Object_, DeviceType > & ptr )

inline

Assignment operator for compatible object types.

It assigns object owned by the pointer ptr to this pointer.

Parameters

ptr	input pointer

Returns: constant reference to this

◆ operator=() [3/4]

template<typename Object >

const DevicePointer & TNL::Pointers::DevicePointer< Object, Devices::Host >::operator= ( DevicePointer< Object, Devices::Host > && ptr )

inlinenoexcept

Move operator.

It assigns object owned by the pointer ptr to this pointer.

Parameters

ptr	input pointer

Returns: constant reference to this

◆ operator=() [4/4]

template<typename Object >

template<typename Object_ , typename = Enabler< Object_ >>

const DevicePointer & TNL::Pointers::DevicePointer< Object, Devices::Host >::operator= ( DevicePointer< Object_, DeviceType > && ptr )

inline

Move operator.

It assigns object owned by the pointer ptr to this pointer.

Parameters
