consteval bool is_pure_virtual( std::meta::info r ); | (since C++26) |
Returns true if r represents a member function that is pure virtual. Otherwise returns false.
Parameters
| r | - | a reflection value |
Return value
true if r represents a member function that is pure virtual; otherwise false.
Example
#include <meta>
struct Base
{
virtual void f() = 0;
};
struct Derived : public Base
{
void f() = 0; // overrides Base::f
virtual void g();
};
static_assert(std::meta::is_pure_virtual(^^Base::f));
static_assert(std::meta::is_pure_virtual(^^Derived::f));
static_assert(!std::meta::is_pure_virtual(^^Derived::g));
int main() {}
