Re: [Boost-users] Using Boost ICL for range matching

2012/6/18 Rajalakshmi Iyer

Hello,

I want to know if I can use the boost::icl::interval_set to store a set of integer based intervals like: [100, 200], [50, 600] etc

and then find out whether a number like 150 matches any of these intervals?

An icl::interval_set does not store the individual intervals that are inserted into it, if they overlap. Basically the interval set is just a set that stores contiguous chunks of elements in a compact way as intervals. So ... #include #include using namespace std; using namespace boost::icl; interval_set<int> aSet; //aSet={} aSet += interval<int>::closed(100,200); //aSet={[100,200]} aSet += interval<int>::closed( 50,600); //aSet={[ 50,600]} cout << "aSet " << (contains(aSet, 150) ? "contains 150\n" : "does not contain 150\n"); The example you ask for will look like this. HTH, Joachim -- Interval Container Library [Boost.Icl] http://www.joachim-faulhaber.de
