move

Interface

template<typename OutputIterator, typename ConstInputIterator>
static SPROUT_CXX14_CONSTEXPR OutputIterator move(OutputIterator s1, ConstInputIterator s2, std::size_t n);

Effects

For each i in [0,n) performs assign(s1[i], p2[i]).

Copies correctly even where the ranges [s2,s2+n) and [s1,s1+n) overlap.

Examples

#include <sprout/string.hpp>
#include <sprout/assert.hpp>
using namespace sprout;

auto x = string<8>("homuhomu");;
SPROUT_STATIC_CONSTEXPR auto y = string<8>("madocchi");
int main() {
  char_traits<char>::move(x.begin(), y.begin(), 8);
  SPROUT_ASSERT_MSG(x[0] == y[0], "y is copied to x.");
}

Complexity

linear.
