Detailed Description

Allows launching any worklet without a dispatcher.

Invoker is a generalized Dispatcher that is able to automatically determine how to properly launch/invoke any worklet that is passed to it. When an Invoker is constructed it is provided the desired device adapter that all worklets invoked by it should be launched on.

Invoker is designed to not only reduce the verbosity of constructing multiple dispatchers inside a block of logic, but also makes it easier to make sure all worklets execute on the same device.

Constructor & Destructor Documentation

Invoker() [1/2]

vtkm::cont::Invoker::Invoker ( )

inlineexplicit

Constructs an Invoker that will try to launch worklets on any device that is enabled.

Invoker() [2/2]

vtkm::cont::Invoker::Invoker ( vtkm::cont::DeviceAdapterId  device )

inlineexplicit

Constructs an Invoker that will try to launch worklets only on the provided device adapter.

Member Function Documentation

GetDevice()

vtkm::cont::DeviceAdapterId vtkm::cont::Invoker::GetDevice ( ) const

inline

Get the device adapter that this Invoker is bound too.

operator()() [1/3]

template<typename Worklet , typename T , typename... Args, typename std::enable_if< detail::scatter_or_mask< T >::value, int >::type * = nullptr>

void vtkm::cont::Invoker::operator() ( Worklet &&  worklet, T &&  scatterOrMask, Args &&...  args  ) const

inline

Launch the worklet that is provided as the first parameter.

Optional second parameter is either the scatter or mask type associated with the worklet. Any additional parameters are the ControlSignature arguments for the worklet.

operator()() [2/3]

template<typename Worklet , typename T , typename U , typename... Args, typename std::enable_if< detail::scatter_or_mask< T >::value &&detail::scatter_or_mask< U >::value, int >::type * = nullptr>

void vtkm::cont::Invoker::operator() ( Worklet &&  worklet, T &&  scatterOrMaskA, U &&  scatterOrMaskB, Args &&...  args  ) const

inline

Launch the worklet that is provided as the first parameter.

Optional second parameter is either the scatter or mask type associated with the worklet. Optional third parameter is either the scatter or mask type associated with the worklet. Any additional parameters are the ControlSignature arguments for the worklet.

operator()() [3/3]

template<typename Worklet , typename T , typename... Args, typename std::enable_if<!detail::scatter_or_mask< T >::value, int >::type * = nullptr>

void vtkm::cont::Invoker::operator() ( Worklet &&  worklet, T &&  t, Args &&...  args  ) const

inline

Launch the worklet that is provided as the first parameter.

Optional second parameter is either the scatter or mask type associated with the worklet. Any additional parameters are the ControlSignature arguments for the worklet.
