Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
SPROUT_CONSTEXPR bool empty() const SPROUT_NOEXCEPT;
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| true if the array size is 0, false otherwise.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/array.hpp>
|
|
using namespace sprout;
|
|
|
|
SPROUT_STATIC_CONSTEXPR auto input = array<int, 0>{{}};
|
|
static_assert(input.empty() == 10, "input is empty.");
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| Recursive function invocations in *O(1)* (constant) depth.
