static DayDelta DayDelta::from_days ( int_delta days )

static

Create a new DayDelta based on a positive or negative number of days.

static DayDelta DayDelta::from_weeks ( int_delta weeks )

static

Create a new DayDelta based on a positive or negative number of weeks.

static DayDelta DayDelta::zero ( )

static

Create a new DayDelta initialized to zero days.

int_delta DayDelta::days ( ) const

Get the number of days represented by a DayDelta.

int_delta DayDelta::weeks ( ) const

Get the number of weeks represented by a DayDelta.

If the DayDelta does not represent an exact number of weeks, the number of weeks will be truncated.

double DayDelta::weeks_decimal ( ) const

Get the number of weeks represented by a DayDelta, with a fractional part if necessary.

TimeDelta DayDelta::to_TimeDelta ( ) const

Convert a DayDelta into an equivalent TimeDelta.

bool DayDelta::is_negative ( ) const
