Description#

Copies the elements from range [first_from, last_from) to another range beginning at first_to (overloads 1,2) or from view_from to view_to (overloads 3,4) replacing with new_value all elements for which pred returns true.

Parameters and Requirements#

  • exespace, first_from, last_from, first_to, view_from, view_to, new_value:

  • label:

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

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

  • pred:

    • unary predicate which returns true for the required element; pred(v) must be valid to be called from the execution space passed, and convertible to bool for every argument v of type (possible const) value_type, where value_type is the value type of InputIteratorType (for 1,2) or of view_from (for 3,4), and must not modify v.

    • should have the same API as that shown for replace_if

Return#

Iterator to the element after the last element copied.
