values_t template<typename... ValueTypes> typedef value_container_t<ValueTypes...> values_t Represents a container to store values in key_frame. The values_t type alias is used to hold the data values associated with the key_frame structure. The container type is determined at compile-time based on the type consistency of the provided value types. If all value types are the same, the container is implemented as a std::array. Otherwise, it is implemented as a std::tuple.
