consteval bool is_bounded_array_type( std::meta::info r );
|
(since C++26) | |
Returns true if r represents an array type of known bound. Otherwise returns false.
Parameters
| r | - | a reflection value |
Return value
true if r represents an array type of known bound; otherwise false.
Exceptions
Throws std::meta::exception if r does not represent a type or type alias.
Example
Run this code
#include <meta>
class A {};
static_assert(!is_bounded_array_type(^^A));
static_assert(!is_bounded_array_type(^^A[]));
static_assert( is_bounded_array_type(^^A[3]));
static_assert(!is_bounded_array_type(^^float));
static_assert(!is_bounded_array_type(^^int));
static_assert(!is_bounded_array_type(^^int[]));
static_assert( is_bounded_array_type(^^int[3]));
int main() {}
