remove_copy_if¶
Header: Kokkos_StdAlgorithms.hpp
Copies the elements from a range to a new range starting at first_to or from view_from to view_dest omitting those for which pred returns true.
Warning
This is currently inside the Kokkos::Experimental namespace.
template <

Overload set accepting a team handle¶
Added in version 4.2.
template <
class TeamHandleType,
class InputIterator, class OutputIterator,
class UnaryPredicate>
KOKKOS_FUNCTION
OutputIterator remove_copy_if(const TeamHandleType& teamHandle, (5)
InputIterator first_from,
InputIterator last_from,
OutputIterator first_to,
const UnaryPredicate& pred);
template <
class TeamHandleType,
class DataType1, class... Properties1,
class DataType2, class... Properties2,
class UnaryPredicate>
KOKKOS_FUNCTION
auto remove_copy_if(const TeamHandleType& teamHandle, (6)
const Kokkos::View<DataType1, Properties1...>& view_from,
const Kokkos::View<DataType2, Properties2...>& view_dest,
const UnaryPredicate& pred);
Parameters and Requirements¶
exespace, teamHandle, first_from, last_from, first_to, view_from, view_dest: same as in remove_copy
label: string forwarded to internal parallel kernels for debugging purposes
1: The default string is “Kokkos::remove_copy_if_iterator_api_default”.
3: The default string is “Kokkos::remove_copy_if_view_api_default”.
NOTE: overloads accepting a team handle do not use a label internally
pred:
unary predicate returning true for the required element to replace; 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 InputIterator (for 1,2,5) or the value type of view (for 3,4,6), and must not modify v.
must conform to:
struct Predicate
{
KOKKOS_INLINE_FUNCTION
bool operator()(const value_type & v) const { return /* ... */; }
// or, also valid
KOKKOS_INLINE_FUNCTION
bool operator()(value_type v) const { return /* ... */; }
};
Iterator to the element after the last element copied.
