NegInfInterval

Represents an interval of time which has negative infinity as its starting point.

Any ranges which iterate over a NegInfInterval are infinite. So, the main purpose of using NegInfInterval is to create an infinite range which starts at negative infinity and goes to a fixed end point. Iterate over it in reverse.

Functions

bwdRange NegInfIntervalRange!(TP) bwdRange(TP delegate(scope const TP) func, PopFirst popFirst): Returns a range which iterates backwards over the interval, starting at end, using func to generate each successive time point.
contains bool contains(TP timePoint): Whether the given time point is within this interval.
contains bool contains(Interval!TP interval): Whether the given interval is completely within this interval.
contains bool contains(PosInfInterval!TP interval): Whether the given interval is completely within this interval.
contains bool contains(NegInfInterval interval): Whether the given interval is completely within this interval.
expand void expand(T years, T months, AllowDayOverflow allowOverflow): Expands the interval forwards and/or backwards in time. Effectively, it adds the given number of months/years to end.
expand void expand(D duration): Expands the interval forwards in time. Effectively, it does end += duration.
intersection Interval!TP intersection(Interval!TP interval): Returns the intersection of two intervals
intersection Interval!TP intersection(PosInfInterval!TP interval): Returns the intersection of two intervals
intersection NegInfInterval intersection(NegInfInterval interval): Returns the intersection of two intervals
intersects bool intersects(Interval!TP interval): Whether the given interval overlaps this interval.
intersects bool intersects(PosInfInterval!TP interval): Whether the given interval overlaps this interval.
intersects bool intersects(NegInfInterval!TP interval): Whether the given interval overlaps this interval.
isAdjacent bool isAdjacent(Interval!TP interval): Whether the given interval is adjacent to this interval.
isAdjacent bool isAdjacent(PosInfInterval!TP interval): Whether the given interval is adjacent to this interval.
isAdjacent bool isAdjacent(NegInfInterval interval): Whether the given interval is adjacent to this interval.
isAfter bool isAfter(TP timePoint): Whether this interval is after the given time point.
isAfter bool isAfter(Interval!TP interval): Whether this interval is after the given interval and does not intersect it.
isAfter bool isAfter(PosInfInterval!TP interval): Whether this interval is after the given interval and does not intersect it.
isAfter bool isAfter(NegInfInterval interval): Whether this interval is after the given interval and does not intersect it.
isBefore bool isBefore(TP timePoint): Whether this interval is before the given time point.
isBefore bool isBefore(Interval!TP interval): Whether this interval is before the given interval and does not intersect it.
isBefore bool isBefore(PosInfInterval!TP interval): Whether this interval is before the given interval and does not intersect it.
isBefore bool isBefore(NegInfInterval interval): Whether this interval is before the given interval and does not intersect it.
merge NegInfInterval merge(Interval!TP interval): Returns the union of two intervals
merge NegInfInterval merge(NegInfInterval interval): Returns the union of two intervals
opAssign NegInfInterval opAssign(NegInfInterval rhs)
opAssign NegInfInterval opAssign(NegInfInterval rhs)
shift void shift(D duration): Shifts the end of this interval forward or backwards in time by the given duration (a positive duration shifts the interval forward; a negative duration shifts it backward). Effectively, it does end += duration.
shift void shift(T years, T months, AllowDayOverflow allowOverflow): Shifts the end of this interval forward or backwards in time by the given number of years and/or months (a positive number of years and months shifts the interval forward; a negative number shifts it backward). It adds the years the given years and months to end. It effectively calls add!"years"() and then add!"months"() on end with the given number of years and months.
span NegInfInterval span(Interval!TP interval): Returns an interval that covers from the earliest time point of two intervals up to (but not including) the latest time point of two intervals.
span NegInfInterval span(NegInfInterval interval): Returns an interval that covers from the earliest time point of two intervals up to (but not including) the latest time point of two intervals.
toString string toString(): Converts this interval to a string.

Properties

end TP end [@property getter]: The end point of the interval. It is excluded from the interval.
end TP end [@property setter]: The end point of the interval. It is excluded from the interval.

Variables

empty enum bool empty;: Whether the interval's length is 0. Always returns false.
