compare

Interface

template<std::size_t N2>
SPROUT_CONSTEXPR int compare(basic_string<T, N2, Traits> const& str) const;

Effects

Determines the effective length rlen of the strings to compare as the smallest of size() and str.size().

The function then compares the two strings by calling traits_type::compare(data(), str.data(), rlen).

Examples

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

SPROUT_STATIC_CONSTEXPR auto x = string<8>("homuhomu");
SPROUT_STATIC_CONSTEXPR auto y = string<8>("madocchi");
SPROUT_STATIC_CONSTEXPR auto result = x.compare(y);
static_assert(result < 0, "x is less than y.");

Complexity

Recursive function invocations in O(logN) (logarithmic) depth.

Note

The current implementation is incomplete. O(N) (linear) depth.
