| [heading Description] |
| |
| `for_each` traverses forward through `rng` and for each element `x` it invokes `fun(x)`. |
| |
| [heading Definition] |
| |
| Defined in the header file `boost/range/algorithm/for_each.hpp` |
| |
| [heading Requirements] |
| |
| * `SinglePassRange` is a model of the __single_pass_range__ Concept. |
| * `UnaryFunction` is a model of the `UnaryFunctionConcept`. |
| * `UnaryFunction` does not apply any non-constant operation through its argument. |
| * `SinglePassRange`'s value type is convertible to `UnaryFunction`'s argument type. |
| |
| [heading Complexity] |
| |
| Linear. Exactly `distance(rng)` applications of `UnaryFunction`. |
