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 that equal old_value. Comparison between elements is done using operator==.
exespace:
execution space instance
label:
used to name the implementation kernels for debugging purposes
for 1, the default string is: “Kokkos::replace_copy_iterator_api_default”
for 3, the default string is: “Kokkos::replace_copy_view_api_default”
first_from, last_from:
range of elements to copy from
must be random access iterators
must represent a valid range, i.e., last_from >= first_from (checked in debug mode)
must be accessible from exespace
first_to:
beginning of the range to copy to
must be a random access iterator
must be accessible from exespace
view_from, view_to:
source and destination views
must be rank-1, and have LayoutLeft, LayoutRight, or LayoutStride
must be accessible from exespace
old_value, new_value:
self-explanatory
Iterator to the element after the last element copied.
