parallel_sort ranges interface extension

parallel_sort ranges interface extension#

Description#

oneAPI Threading Building Blocks (oneTBB) implementation extends the oneapi::tbb::parallel_sort specification with overloads that takes the container by forwarding reference.

API#

Syntax#

namespace oneapi {
    namespace tbb {

        template <typename Container>
        void parallel_sort( Container&& c );
        template <typename Container, typename Compare>
        void parallel_sort( Container&& c, const Compare& comp );

    } // namespace tbb
} // namespace oneapi

Functions#

template<typename Container>
void parallel_sort(Container &&c);#

Equivalent to parallel_sort( std::begin(c), std::end(c), comp ), where comp uses operator< to determine relative orderings.

template<typename Container, typename Compare>
void parallel_sort(Container &&c, const Compare &comp);#

Equivalent to parallel_sort( std::begin(c), std::end(c), comp ).

Example#

This interface may be used for sorting rvalue or constant views:

#include <array>
#include <span> // requires C++20
#include <oneapi/tbb/parallel_sort.h>

std::span<int> get_span() {
    static std::array<int, 3> arr = {3, 2, 1};
    return std::span<int>(arr);
}

int main() {
    tbb::parallel_sort(get_span());
}
