[heading Description]
|
||
|
|
|
||
|
|
`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`.
|
||
|
|
|
||
|
|
[heading Definition]
|
||
|
|
|
||
|
|
Defined in the header file `boost/range/algorithm/replace_copy_if.hpp`
|
||
|
|
|
||
|
|
[heading Requirements]
|
||
|
|
|
||
|
|
* `ForwardRange` is a model of the __forward_range__ Concept.
|
||
|
|
* `ForwardRange` is mutable.
|
||
|
|
* `Value` is convertible to `ForwardRange`'s value type.
|
||
|
|
* `Value` is a model of the `AssignableConcept`.
|
||
|
|
* `OutputIterator` is a model of the `OutputIteratorConcept`.
|
||
|
|
* `UnaryPredicate` is a model of the `UnaryPredicateConcept`.
|
||
|
|
|
||
|
|
[heading Complexity]
|
||
|
|
|
||
|
|
Linear. `replace_copy_if` performs exactly `distance(rng)` evaluations of `pred`.
