[heading Description]
|
|
|
|
`for_each` traverses forward through `rng1` and `rng2` simultaneously.
|
|
For each iteration, the element `x` is used from `rng1` and the corresponding
|
|
element `y` is used from `rng2` to invoke `fn(x,y)`.
|
|
|
|
Iteration is stopped upon reaching the end of the shorter of `rng1`, or `rng2`.
|
|
It is safe to call this function with unequal length ranges.
|
|
|
|
[heading Definition]
|
|
|
|
Defined in the header file `boost/range/algorithm_ext/for_each.hpp`
|
|
|
|
[heading Requirements]
|
|
|
|
# `SinglePassRange1` is a model of the __single_pass_range__ Concept.
|
|
# `SinglePassRange2` is a model of the __single_pass_range__ Concept.
|
|
# `BinaryFunction` is a model of the `BinaryFunctionConcept`.
|
|
# `SinglePassRange1`'s value type is convertible to `BinaryFunction`'s first argument type.
|
|
# `SinglepassRange2`'s value type is convertible to `BinaryFunction`'s second argument type.
|
|
|
|
[heading Complexity]
|
|
|
|
Linear. Exactly `min(distance(rng1), distance(rng2))` applications of `BinaryFunction`.
