Public Functions

template<typename ArgT, typename ...ArgsT, typename = std::enable_if_t<!std::is_base_of_v<Resource, std::decay_t<ArgT>> && (std::is_same_v<Arg, std::decay_t<ArgT>> || std::is_same_v<ArgList, std::decay_t<ArgT>>)>>
inline Clock(ArgT &&arg, ArgsT&&... args)

Clock() = default

Clock(const std::string &name, nvidia::gxf::Clock *component)

inline virtual const char *gxf_typename() const override

The underlying GXF component’s name.

virtual double time() const = 0

The current time of the clock. Time is measured in seconds.

virtual int64_t timestamp() const = 0

virtual void sleep_for(int64_t duration_ns) = 0

Waits until the given duration has elapsed on the clock.

template<typename Rep, typename Period>
inline void sleep_for(std::chrono::duration<Rep, Period> duration)
