remove_copy
¶
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 that are equal to value
.
Warning
This is currently inside the Kokkos::Experimental
namespace.
template < class ExecutionSpace, class InputIterator, class OutputIterator, class ValueType> OutputIterator remove_copy(const ExecutionSpace& exespace, (1) InputIterator first_from, InputIterator last_from, OutputIterator first_to, const ValueType& value); template < class ExecutionSpace, class InputIterator, class OutputIterator, class ValueType> OutputIterator remove_copy(const std::string& label, (2) const ExecutionSpace& exespace, InputIterator first_from, InputIterator last_from, OutputIterator first_to, const ValueType& value); template < class ExecutionSpace, class DataType1, class...

Added in version 4.2.
template < class TeamHandleType, class InputIterator, class OutputIterator, class ValueType> KOKKOS_FUNCTION OutputIterator remove_copy(const TeamHandleType& teamHandle, (5) InputIterator first_from, InputIterator last_from, OutputIterator first_to, const ValueType& value); template < class TeamHandleType, class DataType1, class... Properties1, class DataType2, class... Properties2, class ValueType> KOKKOS_FUNCTION auto remove_copy(const TeamHandleType& teamHandle, (6) const Kokkos::View<DataType1, Properties1...>& view_from, const Kokkos::View<DataType2, Properties2...>& view_dest, const ValueType& value);Parameters and Requirements¶
exespace
: execution space instance
teamHandle
: team handle instance given inside a parallel region when using a TeamPolicy
label
: string forwarded to internal parallel kernels for debugging purposes
1: The default string is “Kokkos::remove_copy_iterator_api_default”.
3: The default string is “Kokkos::remove_copy_view_api_default”.
NOTE: overloads accepting a team handle do not use a label internally
first_from, last_from
: range of elements to copy from
must be random access iterators, e.g., returned from Kokkos::Experimental::(c)begin/(c)end
must represent a valid range, i.e., last >= first
must be accessible from exespace
or from the execution space associated with the team handle
first_to
: beginning of the range to copy to
must be random access iterators, e.g., returned from Kokkos::Experimental::(c)begin/(c)end
must be accessible from exespace
or from the execution space associated with the team handle
view_from
, view_dest
: source and destination views
must be rank-1, and have LayoutLeft
, LayoutRight
, or LayoutStride
must be accessible from exespace
or from the execution space associated with the team handle
value
: target value to omit
Iterator to the element after the last element copied.
