*Hi folks* * * *I have the following use case: I want to store a series of time intervals in an icl::interval_set and then determine whether a single point in time intersects one of these intervals.* * * *Here is my first stab at this: * icl::interval_set<Time> _badMonths; // Time is an internal class which defines all comparison operators std::vector<int> badMonths; // populated with YYMM integers (eg: 1206 for June 2012) for (int m : badMonths) { Time openInterval = Time(2000 + m / 100, m % 100, 1); // 1st day of the month Time closeInterval = Time(2000 + m / 100, m % 100 + 1, 1) - TimeSpan::Days(1); // last day of the month icl::interval<Time>::type month(openInterval, closeInterval); _badMonths.insert(month); } // it is now my hope that _badMonths will contain a set of intervals where each interval is a month *How do I now check whether a single Time instance intersects one of the intervals in the set? * Time timepoint; if (_badMonths &= timepoint) std::cout << timepoint << " intersects bad months" << std::endl; TIA Steve
