Detailed Description

The place for clock drivers; a way to use time keeping devices.

Usually there is a way to query the operating system for the time, so many classes will not require hardware support.

Typedef Documentation

◆ Clock

typedef GenericClock< duds::data::GenericValue, double, duds::time::interstellar::NanoTime, float> duds::hardware::devices::clocks::Clock

General use clock driver type.

Definition at line 261 of file Clock.hpp.

◆ ClockSptr

typedef std::shared_ptr<Clock> duds::hardware::devices::clocks::ClockSptr

Definition at line 263 of file Clock.hpp.

◆ CppClock

typedef GenericCppClock< duds::time::interstellar::NanoClock, duds::data::GenericValue, double, duds::time::interstellar::NanoTime, float> duds::hardware::devices::clocks::CppClock

General use C++ clock driver type.

Definition at line 133 of file CppClock.hpp.

◆ CppClockSptr

typedef std::shared_ptr<CppClock> duds::hardware::devices::clocks::CppClockSptr

Definition at line 135 of file CppClock.hpp.

◆ FemtoTimeSample

typedef duds::data::GenericSample<duds::time::interstellar::FemtoTime, double> duds::hardware::devices::clocks::FemtoTimeSample

A time sample fit for applications requiring very long-term time samples, or time samples with high resolution.

FemtoTime should be able to hold any point in time from the begining of the universe until the last star goes dark. Doubles for the quality data should be able to represent the best clocks for at least a few centuries and possibly much longer.

Definition at line 47 of file Clock.hpp.

◆ LinuxClock

typedef GenericLinuxClock< duds::data::GenericValue, double, duds::time::interstellar::NanoTime, float> duds::hardware::devices::clocks::LinuxClock

General use Linux clock driver type.

Definition at line 202 of file LinuxClock.hpp.

◆ LinuxClockSptr

typedef std::shared_ptr<LinuxClock> duds::hardware::devices::clocks::LinuxClockSptr

Definition at line 204 of file LinuxClock.hpp.

◆ NanoTimeSample

typedef duds::data::GenericSample<duds::time::interstellar::NanoTime, float> duds::hardware::devices::clocks::NanoTimeSample

A compact time sample that works well for most purposes.

NanoTime is used to minimize memory use. Floats for the quality type complements this, while providing adequate range to properly represent the best atomic clocks.

Definition at line 36 of file Clock.hpp.

◆ PosixClock

typedef GenericPosixClock< duds::data::GenericValue, double, duds::time::interstellar::NanoTime, float> duds::hardware::devices::clocks::PosixClock

General use POSIX clock driver type.

Definition at line 250 of file PosixClock.hpp.

◆ PosixClockId

typedef boost::error_info<struct Info_posixclockid, clockid_t> duds::hardware::devices::clocks::PosixClockId

Indicates the POSIX clockid_t in an error involving a POSIX clock.

Definition at line 37 of file PosixClock.hpp.

◆ PosixClockSptr

typedef std::shared_ptr<PosixClock> duds::hardware::devices::clocks::PosixClockSptr

Definition at line 252 of file PosixClock.hpp.

◆ TimeSample

typedef NanoTimeSample duds::hardware::devices::clocks::TimeSample

The regular time sample is currently NanoTimeSample for practicality.

Definition at line 52 of file Clock.hpp.

Variable Documentation

◆ CppClockDeviceId

constexpr boost::uuids::uuid duds::hardware::devices::clocks::CppClockDeviceId

    0x43, 0xde,
    0x97, 0xac,
    0xd2, 0xea, 0x2a, 0x48, 0x51, 0xb2
}

The UUID for the C++ clock device.

Definition at line 20 of file CppClock.hpp.

◆ LinuxClockDeviceId

constexpr boost::uuids::uuid duds::hardware::devices::clocks::LinuxClockDeviceId

Initial value:

= {
    0xbf, 0x2d, 0x4a, 0x68,
    0x62, 0xda,
    0x45, 0x56,
    0x8c, 0xc6,
    0x38, 0xd1, 0xd5, 0x5b, 0x20, 0x74
}

The UUID for the Linux clock device.

Definition at line 25 of file LinuxClock.hpp.

◆ PosixClockDeviceId

constexpr boost::uuids::uuid duds::hardware::devices::clocks::PosixClockDeviceId

Initial value:

= {
    0x41, 0xba, 0xe3, 0x09,
    0xc2, 0xe9,
    0x4c, 0x02,
