std.datetime.interval.Interval.isBefore - multiple declarations

Function Interval.isBefore

Whether this interval is before the given time point.

bool isBefore (
  scope const TP timePoint
) const pure;

Parameters

NameDescription
timePoint The time point to check whether this interval is before it.

Throws

DateTimeException if this interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            Date(1994, 12, 24)));

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            Date(2000, 1, 5)));

assert(Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            Date(2012, 3, 1)));

Function Interval.isBefore

Whether this interval is before the given interval and does not intersect with it.

bool isBefore (
  scope const Interval interval
) const pure;

Parameters

NameDescription
interval The interval to check for against this interval.

Throws

DateTimeException if either interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            Interval!Date(Date(1990, 7, 6), Date(2000, 8, 2))));

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            Interval!Date(Date(1999, 1, 12), Date(2011, 9, 17))));

assert(Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            Interval!Date(Date(2012, 3, 1), Date(2013, 5, 1))));

Function Interval.isBefore

Whether this interval is before the given interval and does not intersect with it.

bool isBefore (
  scope const PosInfInterval!TP interval
) const pure;

Parameters

NameDescription
interval The interval to check for against this interval.

Throws

DateTimeException if this interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            PosInfInterval!Date(Date(1999, 5, 4))));

assert(Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            PosInfInterval!Date(Date(2013, 3, 7))));

Function Interval.isBefore

Whether this interval is before the given interval and does not intersect with it.

bool isBefore (
  scope const NegInfInterval!TP interval
) const pure;

Always returns false (unless this interval is empty) because a finite interval can never be before an interval beginning at negative infinity.

Parameters

NameDescription
interval The interval to check for against this interval.

Throws

DateTimeException if this interval is empty.

Example

assert(!Interval!Date(Date(1996, 1, 2), Date(2012, 3, 1)).isBefore(
            NegInfInterval!Date(Date(1996, 5, 4))));
