16[heading Description]
17
18`replace_copy_if` copy every element `x` in `rng` such that the corresponding element in the output range `y` is `pred(x) ? with_what : x`.
19
20[heading Definition]
21
22Defined in the header file `boost/range/algorithm/replace_copy_if.hpp`
23
24[heading Requirements]
25
26* `ForwardRange` is a model of the __forward_range__ Concept.
27* `ForwardRange` is mutable.
28* `Value` is convertible to `ForwardRange`'s value type.
29* `Value` is a model of the `AssignableConcept`.
30* `OutputIterator` is a model of the `OutputIteratorConcept`.
31* `UnaryPredicate` is a model of the `UnaryPredicateConcept`.
32
33[heading Complexity]
34
35Linear. `replace_copy_if` performs exactly `distance(rng)` evaluations of `pred`.
