date_duration public construct/copy/destruct

  1. explicit date_duration(duration_rep day_count = 0);
    Construct from a day count.
  2. date_duration(date_time::special_values sv);
    construct from special_values
  3. date_duration(const base_type & other);
    Construct from another date_duration.

date_duration public member functions

  1. BOOST_CXX14_CONSTEXPR bool operator==(const date_duration & rhs) const;
  2. BOOST_CXX14_CONSTEXPR bool operator!=(const date_duration & rhs) const;
  3. BOOST_CXX14_CONSTEXPR bool operator<(const date_duration & rhs) const;
  4. BOOST_CXX14_CONSTEXPR bool operator>(const date_duration & rhs) const;
  5. BOOST_CXX14_CONSTEXPR bool operator<=(const date_duration & rhs) const;
  6. BOOST_CXX14_CONSTEXPR bool operator>=(const date_duration & rhs) const;
  7. BOOST_CXX14_CONSTEXPR date_duration & operator-=(const date_duration & rhs);
    Subtract another duration – result is signed.
  8. BOOST_CXX14_CONSTEXPR date_duration & operator+=(const date_duration & rhs);
    Add a duration – result is signed.
  9. BOOST_CXX14_CONSTEXPR date_duration operator-() const;
    unary- Allows for dd = -date_duration(2); -> dd == -2
  10. BOOST_CXX14_CONSTEXPR date_duration & operator/=(int divisor);
    Division operations on a duration with an integer.

date_duration public static functions

  1. static BOOST_CXX14_CONSTEXPR date_duration unit();
    Returns the smallest duration – used by to calculate 'end'.
