GRBException#

class GRBException : public std::runtime_error#

Gurobi exception object. Exceptions can be thrown by nearly every method in the Gurobi C++ API. GRBException inherits from std::runtime_error which allows you to catch Gurobi exceptions not only via:

catch (const GRBException& e) {
  cout << e.getMessage() << endl;
}

but also as standard C++ exceptions, such as:

catch (const std::runtime_error& e) {
  cout << e.what() << endl;
}

or:

catch (const std::exception& e) {
  cout << e.what() << endl;
}
