build_multi_function_call_from_element_fn()

template<typename ElementFn , typename ExecPreset , typename... ParamTags>

auto blender::fn::multi_function::build::detail::build_multi_function_call_from_element_fn ( const ElementFn element_fn, const ExecPreset exec_preset, TypeSequence< ParamTags... >  )

inline

element_fn is expected to return nothing and to have the following parameters:

• For single-inputs: const value or reference.
• For single-mutables: non-const reference.
• For single-outputs: non-const pointer.

execute_array()

template<typename MaskT , typename... Args, typename... ParamTags, size_t... I, typename ElementFn >

void blender::fn::multi_function::build::detail::execute_array ( TypeSequence< ParamTags... > , std::index_sequence< I... > , ElementFn element_fn, MaskT mask, Args &&__restrict... args )

inline

Executes #element_fn for all indices in the mask. The passed in #args contain the input as well as output parameters. Usually types in #args are devirtualized (e.g. a Span<int> is passed in instead of a VArray<int>).

inline

Executes #element_fn for all indices in #mask. However, instead of processing every element separately, processing happens in chunks. This allows retrieving from input virtual arrays in chunks, which reduces virtual function call overhead.

void blender::fn::multi_function::build::detail::execute_materialized_impl ( TypeSequence< ParamTags... > , const ElementFn element_fn, const int64_t size, Chunks &&__restrict... chunks )

inline

Similar to execute_array but is only used with arrays and does not need a mask.
