Description#

Reverses ther order of the elements in the range [first, last) (overloads 1,2) or in view (overloads 3,4).

Parameters and Requirements#

  • exespace:

    • execution space instance

  • label:

    • used to name the implementation kernels for debugging purposes

    • for 1, the default string is: “Kokkos::reverse_iterator_api_default”

    • for 3, the default string is: “Kokkos::reverse_view_api_default”

  • first, last:

    • range of elements to reverse

    • must be random access iterators

    • must represent a valid range, i.e., last >= first (this condition is checked in debug mode)

    • must be accessible from exespace

  • view:

    • must be rank-1, and have LayoutLeft, LayoutRight, or LayoutStride

    • must be accessible from exespace

Return#

None
