Function NegInfInterval.isBefore
Whether this interval is before the given interval and does not
intersect it.
Always returns false because an interval beginning at negative
infinity can never be before another interval beginning at negative
infinity.
Prototype
bool isBefore( NegInfInterval interval ) const pure nothrow;
Parameters
| Name | Description |
|---|---|
| interval | The interval to check for against this interval. |
Examples
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))));
Function NegInfInterval.isBefore
Whether this interval is before the given interval and does not
intersect it.
Prototype
bool isBefore( PosInfInterval!TP interval ) const pure nothrow;
Parameters
| Name | Description |
|---|---|
| interval | The interval to check for against this interval. |
Examples
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.
Prototype
bool isBefore( Interval!TP interval ) const pure;
Parameters
| Name | Description |
|---|---|
| interval | The interval to check for against this interval. |
Throws
DateTimeException if the given interval is empty
Examples
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 time point.
Prototype
bool isBefore( TP timePoint ) const pure nothrow;
Parameters
| Name | Description |
|---|---|
| timePoint | The time point to check whether this interval is before it. |
Examples
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)));
