NegInfInterval.merge

NegInfInterval merge(scope const Interval!TP interval) const

Returns the union of two intervals

Parameters

interval The interval to merge with this interval.

Throws

DateTimeException if the two intervals do

not intersect and are not adjacent or if the given interval is empty.

Note

There is no overload for merge which takes a

PosInfInterval, because an interval going from negative infinity to positive infinity is not possible.

Example: -------------------- assert(NegInfInterval!Date(Date(2012, 3, 1)).merge( Interval!Date(Date(1990, 7, 6), Date(2000, 8, 2))) == NegInfInterval!Date(Date(2012, 3 , 1)));

assert(NegInfInterval!Date(Date(2012, 3, 1)).merge( Interval!Date(Date(1999, 1, 12), Date(2015, 9, 2))) == NegInfInterval!Date(Date(2015, 9 , 2))); --------------------
