int Deepsolver::OperationCoreException::getCode | ( | ) | const [inline] |
std::string Deepsolver::OperationCoreException::getMessage | ( | ) | const [virtual] |

std::string Deepsolver::OperationCoreException::getParam | ( | ) | const [inline] |
std::string Deepsolver::OperationCoreException::getType | ( | ) | const [inline, virtual] |
This method returns a short string with one or two words describing the error type. For example, this method can return values like "system", "back-end" etc. A value returned by this method usually is used for error message construction.
