Has any thought been given to the implementation of unbounded intervals? Right-unbounded intervals (extending into the future) are often used as to represent an event that has begun, but has not yet ended.
Whenever I need to permit an interval to be unbounded, I always use two DateTimes instead, and allow one or both to have null values. There are some disadvantages to this approach. One is that every person who does this must write their own implementations of the interval methods (contains, abuts, overlaps, etc.). Another disadvantage is that the two DateTimes cannot be used as a key to a map in the same way that an Interval can, unless they are wrapped in a container class. An alternative approach is to use Interval, with DateTime values sufficiently far in the past/future representing infinity in either direction. I don't like this approach because it feels imprecise, but it is a quick and dirty way of getting Joda time to represent unbounded intervals. It would be nice if Joda had the ability to represent unbounded intervals without such tricks. I'd be happy to help implement this functionality if there is an interest. If there is an interest, how might this be integrated? Add this functionality to the current Interval implementation, or create a new type of interval capable of representing unbounded intervals? ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
