all_of

Interface

C++

template<typename InputIterator, typename Predicate> inline SPROUT_CONSTEXPR bool all_of(InputIterator first, InputIterator last, Predicate pred);

Returns

true if [first,last) is empty or if pred(*i) is true for every iterator i in the range [first,last), and false otherwise.

Examples

C++

#include <sprout/algorithm/all_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::all_of(begin(input), end(input), bind2nd(less<>(), 11)); static_assert(result, "all of input is less than 11.");

Complexity

At most last - first applications of the predicate.

Recursive function invocations in O(N) (linear) depth.
