Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
void assign(const_reference value);
|
|
|
|
SPROUT_CONSTEXPR array assign(const_reference value) const;
|
|
|
|
Effects
|
|
========================================
|
|
|
|
| ``std::fill_n(begin(), N, value)``, or without effects in the case of const version.
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| void, or array filled with value in the case of const version.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/array.hpp>
|
|
#include <sprout/assert.hpp>
|
|
using namespace sprout;
|
|
|
|
auto x = array<int, 10>{{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}};
|
|
x.assign(0);
|
|
SPROUT_ASSERT_MSG(x[0] = 0, "filled with 0.");
|
|
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/array.hpp>
|
|
using namespace sprout;
|
|
|
|
SPROUT_STATIC_CONSTEXPR auto x = array<int, 10>{{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}};
|
|
SPROUT_STATIC_CONSTEXPR auto y = x.assign(0);
|
|
static_assert(y[0] = 0, "filled with 0.");
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| Recursive function invocations in *O(1)* (constant) depth.
|
|
