template<typename... Ts>

template<SIZE_T N>

auto && UE::Core::Private::TVariantStorage< Ts >::GetValueAsIndexedType ( ) &&

inline

Interpret the underlying data as the type in the variant parameter pack at the compile-time index. This function is used to implement Visit and should not be used directly
