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
Name | Description |
---|---|
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.
Parameters
Name | Description |
---|---|
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.
Parameters
Name | Description |
---|---|
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.
Always returns false (unless this interval is empty) because a finite interval can never be before an interval beginning at negative infinity.
Parameters
Name | Description |
---|---|
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))));
