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

Function PosInfInterval.isBefore

Whether this interval is before the given time point.

bool isBefore (
  in TP timePoint
) const pure nothrow;

Always returns false because an interval going to positive infinity can never be before any time point.

Parameters

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

Example

assert(!PosInfInterval!Date(Date(1996, 1, 2)).isBefore(Date(1994, 12, 24)));
assert(!PosInfInterval!Date(Date(1996, 1, 2)).isBefore(Date(2000, 1, 5)));

Function PosInfInterval.isBefore

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

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

Always returns false (unless the given interval is empty) because an interval going to positive infinity can never be before any other interval.

Parameters

NameDescription
interval The interval to check for against this interval.

Throws

DateTimeException if the given interval is empty.

Example

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

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

Function PosInfInterval.isBefore

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

bool isBefore (
  in PosInfInterval interval
) const pure nothrow;

Always returns false because an interval going to positive infinity can never be before any other interval.

Parameters

NameDescription
interval The interval to check for against this interval.

Example

assert(!PosInfInterval!Date(Date(1996, 1, 2)).isBefore(
            PosInfInterval!Date(Date(1992, 5, 4))));

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

Function PosInfInterval.isBefore

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

bool isBefore (
  in NegInfInterval!TP interval
) const pure nothrow;

Always returns false because an interval going to positive infinity can never be before any other interval.

Parameters

NameDescription
interval The interval to check for against this interval.

Example

assert(!PosInfInterval!Date(Date(1996, 1, 2)).isBefore(
            NegInfInterval!Date(Date(1996, 5, 4))));
