std::meta::is_class_template
Defined in header <meta> | ||
|---|---|---|
consteval bool is_class_template( std::meta::info r ); | (since C++26) |
Returns true if r represents a class template. Otherwise returns false.
Parameters
| r | - | a reflection value |
Return value
true if r represents a class template; otherwise false.
Notes
A class template specialization is not a template. For example,
-
std::meta::is_class_template(^^std::list)is true but -
std::meta::is_class_template(^^std::list<short>)is false.
Example
#include <meta>
// class
struct S1;
static_assert(!std::meta::is_class_template(^^S1));
// class template
template<class T>
union S2;
static_assert(std::meta::is_class_template(^^S2));
int main() {}
