std.datetime.pos_inf_interval.is_before - multiple declarations

Function PosInfInterval.isBefore

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

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

Prototype

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

Parameters

NameDescription
interval The interval to check for against this interval.

Examples

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

Function PosInfInterval.isBefore

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

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

Prototype

bool isBefore(
  PosInfInterval interval
) const pure nothrow;

Parameters

NameDescription
interval The interval to check for against this interval.

Examples

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.

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

Prototype

bool isBefore(
  Interval!TP interval
) const pure;

Parameters

NameDescription
interval The interval to check for against this interval.

Throws

DateTimeException if the given interval is empty.

Examples

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 time point.

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

Prototype

bool isBefore(
  TP timePoint
) const pure nothrow;

Parameters

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

Examples

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