| 24 | [heading Description] | |
| 25 | ||
| 26 | `for_each` traverses forward through `rng` and for each element `x` it invokes `fun(x)`. | |
| 27 | ||
| 28 | [heading Definition] | |
| 29 | ||
| 30 | Defined in the header file `boost/range/algorithm/for_each.hpp` | |
| 31 | ||
| 32 | [heading Requirements] | |
| 33 | ||
| 34 | * `SinglePassRange` is a model of the __single_pass_range__ Concept. | |
| 35 | * `UnaryFunction` is a model of the `UnaryFunctionConcept`. | |
| 36 | * `UnaryFunction` does not apply any non-constant operation through its argument. | |
| 37 | * `SinglePassRange`'s value type is convertible to `UnaryFunction`'s argument type. | |
| 38 | ||
| 39 | [heading Complexity] | |
| 40 | ||
| 41 | Linear. Exactly `distance(rng)` applications of `UnaryFunction`. | |
