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

Function NegInfInterval.isBefore

Whether this interval is before the given time point.

bool isBefore (
  scope const TP timePoint
) const pure nothrow;

Parameters

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

Example

assert(!NegInfInterval!Date(Date(2012, 3, 1)).isBefore(Date(1994, 12, 24)));
assert(!NegInfInterval!Date(Date(2012, 3, 1)).isBefore(Date(2000, 1, 5)));
assert(NegInfInterval!Date(Date(2012, 3, 1)).isBefore(Date(2012, 3, 1)));

Function NegInfInterval.isBefore

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

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

Parameters

NameDescription
interval The interval to check for against this interval.

Throws

DateTimeException if the given interval is empty

Example

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

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

assert(NegInfInterval!Date(Date(2012, 3, 1)).isBefore(
            Interval!Date(Date(2022, 10, 19), Date(2027, 6, 3))));

Function NegInfInterval.isBefore

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

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

Parameters

NameDescription
interval The interval to check for against this interval.

Example

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

assert(NegInfInterval!Date(Date(2012, 3, 1)).isBefore(
            PosInfInterval!Date(Date(2012, 3, 1))));

Function NegInfInterval.isBefore

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

bool isBefore (
  scope const NegInfInterval interval
) const pure nothrow;

Always returns false because an interval beginning at negative infinity can never be before another interval beginning at negative infinity.

Parameters

NameDescription
interval The interval to check for against this interval.

Example

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

assert(!NegInfInterval!Date(Date(2012, 3, 1)).isBefore(
            NegInfInterval!Date(Date(2013, 7, 9))));
