C++ (Cpp) Interval::is_empty Examples

Example #1

File: box.cpp Project: jadecastro/dreal3

bool operator<(ibex::Interval const & a, ibex::Interval const & b) {
    if (a.is_empty() || b.is_empty()) {
        return false;
    }
    return a.ub() < b.lb();
    return false;
}

Example #2

File: Tube.cpp Project: SimonRohou/pyIbex

{
  if(!intv_t.is_empty() && m_intv_t.intersects(intv_t))
  {

      return make_pair(ui_past.first | ui_future.first, ui_past.second | ui_future.second);
    }
  }
