Member Function Documentation

◆ getData()

template<typename Object >

template<typename Device = Devices::Host>

__cuda_callable__ const Object & TNL::Pointers::SharedPointer< 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::SharedPointer< 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()
