Return value
true if r represents a member function that overrides another member function; otherwise false.
Example
#include <meta>
struct Base
{
virtual void f() = 0;
void g(); // non-virtual
};
struct Derived : public Base
{
void f() = 0; // overrides Base::f
virtual void g(); // does not override Base::g
};
static_assert(!std::meta::is_override(^^Base::f));
static_assert(std::meta::is_override(^^Derived::f));
static_assert(!std::meta::is_override(^^Derived::g));
int main() {}
