reflection operator (since C++26) The unary ^^ operator, called the reflection operator, yields the reflection of the given language construct, of type std::meta::info.

The facilities defined in this section support reflective programming, allowing C++ programs to both observe the structure of the program itself and to generate code that depends on those observations.

The C++ Extensions for Reflection, ISO/IEC TS 23619:2021, specifies modifications to the core language and defines new components for the C++ standard library listed on this page. The …

Let E be std::meta::reflect_constant(expr) (where expr is the constant-expression), E must be a constant expression. The result of E can be observed by calling std::meta::constant_of on the reflection of the …

C++ keyword: reflexpr (reflection TS) Experimental Feature The functionality described on this page is part of the Reflection Technical Specification ISO/IEC TS 23619 (reflection TS).

The reflection_range concept defines the requirements of a type that represents a sequence of reflection values and can be passed to reflection functions. Example

std::is_reflection is a UnaryTypeTrait. Checks whether T is the type std::meta::info. Provides the member constant value that is equal to true, if T is the type std ...

The Operator concept is satisfied if and only if T reflects an operator function or a conversion function (Note: Some types that satisfy Operator also satisfy MemberFunction or SpecialMemberFunction).
