Hi all, I'm trying to use interval_map to implement some kind of range to value directory, but I have some non expected results. The test code I'm using is: ------------------------ #include <iostream> #include <boost/icl/interval_map.hpp> #include <boost/icl/discrete_interval.hpp> using namespace std; using namespace boost::icl; int main(int argc, char const **argv) { interval_map<size_t, int> imap; typedef discrete_interval<size_t> interval_t; imap += make_pair(construct<interval_t>(0, 7, interval_bounds::closed()),0); cout << "imap: " << imap << endl; imap.set(make_pair(construct<interval_t>(0, 0, interval_bounds::closed()),1)); cout << "imap: " << imap << endl; imap.erase(construct<interval_t>(3, 3, interval_bounds::closed())); cout << "imap: " << imap << endl; } ------------------------ The result I got is: imap: {} imap: {([0,0]->1)} imap: {([0,0]->1)} but the result I was expecting is: imap: {([0,7]->0)} imap: {([0,0]->1)((0,7]->0)} imap: {([0,0]->1)((0,3)->0)((3,7]->0)} Do I missing something? Thanks, Antal
