static const auto* get_implementation ( const SelectorType &  selector,
KernelSelectionType  selection_type = KernelSelectionType::Supported 
)
inlinestatic

Micro-kernel selector.

Parameters
[in]selectorSelection struct passed including information to help pick the appropriate micro-kernel
[in]selection_type(Optional) Decides whether to get the best implementation for the given hardware or for the given build
Returns
