std.datetime.interval.PosInfInterval.shift - multiple declarations
Function PosInfInterval.shift
Shifts the begin of this interval forward or backwards in time by
the given duration (a positive duration shifts the interval forward; a
negative duration shifts it backward). Effectively, it does
begin += duration.
void shift(D)(
D duration
) pure nothrow
if (__traits(compiles, begin + duration));
Parameters
| Name | Description |
|---|---|
| duration | The duration to shift the interval by. |
Example
auto interval1 = PosInfInterval!Date(Date(1996, 1, 2));
auto interval2 = PosInfInterval!Date(Date(1996, 1, 2));
interval1Function PosInfInterval.shift
Shifts the begin of this interval forward or backwards in time
by the given number of years and/or months (a positive number of
years and months shifts the interval forward; a negative number
shifts it backward). It adds the years the given years and months to
begin. It effectively calls add!"years"() and then
add!"months"() on begin with the given number of years and
months.
void shift(T)(
T years,
T months = 0,
AllowDayOverflow allowOverflow = AllowDayOverflow
)
if (isIntegral!T);
Parameters
| Name | Description |
|---|---|
| years | The number of years to shift the interval by. |
| months | The number of months to shift the interval by. |
| allowOverflow | Whether the days should be allowed to overflow
on begin, causing its month to increment. |
Throws
DateTimeException if this interval is
empty or if the resulting interval would be invalid.
Example
auto interval1 = PosInfInterval!Date(Date(1996, 1, 2));
auto interval2 = PosInfInterval!Date(Date(1996, 1, 2));
