Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
template<typename InputIterator, typename Predicate>
|
|
inline SPROUT_CONSTEXPR bool
|
|
none_of(InputIterator first, InputIterator last, Predicate pred);
|
|
|
|
Returns
|
|
========================================
|
|
|
|
*true* if [first,last) is empty or if ``pred(*i)`` is false for every iterator i in the range [first,last), and *false* otherwise.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/algorithm/none_of.hpp>
|
|
#include <sprout/array.hpp>
|
|
#include <sprout/container.hpp>
|
|
#include <sprout/functional.hpp>
|
|
using namespace sprout;
|
|
|
|
SPROUT_STATIC_CONSTEXPR auto input = array<int, 10>{{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}};
|
|
SPROUT_STATIC_CONSTEXPR auto result = sprout::none_of(begin(input), end(input), bind2nd(greater<>(), 10));
|
|
static_assert(result, "none of input is greater than 10.");
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
At most ``last - first`` applications of the predicate.
|
|
|
|
Recursive function invocations in *O(logN)* (logarithmic) depth.
|
