Function type_id
Summary
#include <src/entt/core/type_info.hpp>
(1) template <typename Type>
const type_info & type_id()
(2) template <typename Type>
const type_info & type_id(Type &&)
Function overload
Synopsis
#include <src/entt/core/type_info.hpp>
template <typename Type>
const type_info & type_id()
Description
Returns the type info object associated to a given type.
The returned element refers to an object with static storage duration.
The type doesn't need to be a complete type. If the type is a reference, the result refers to the referenced type. In all cases, top-level cv-qualifiers are ignored.
- Template Parameters
Type- Type for which to generate a type info object.- Returns
- A reference to a properly initialized type info object.
Mentioned in
- Core Functionalities / Any as in any type
- Core Functionalities / Type info
- Entity Component System / A base class to rule them all
- Runtime Reflection System / Enjoy the runtime
