[heading Description]
|
|
|
|
The versions of `find` that return an iterator, returns the first iterator in the range `rng` such that `*i == value`. `end(rng)` is returned if no such iterator exists.
|
|
The versions of find that return a `range_return`, defines `found` in the same manner as the returned iterator described above.
|
|
|
|
[heading Definition]
|
|
|
|
Defined in the header file `boost/range/algorithm/find.hpp`
|
|
|
|
[heading Requirements]
|
|
|
|
* `SinglePassRange` is a model of the __single_pass_range__ Concept.
|
|
* `Value` is a model of the `EqualityComparableConcept`.
|
|
* The `operator==` is defined for type `Value` to be compared with the `SinglePassRange`'s value type.
|
|
|
|
[heading Complexity]
|
|
|
|
Linear. At most `distance(rng)` comparisons for equality.
