Cpp exceptions

C++ comes with an exception system, but it is not quite as convenient as the python exception system.

Usage

TODO:

I need to test this out and see if I can define my own exceptions that come bundled with a type, and a provided description of the error.

// exception inheriting from exception
class InvalidIdError: public exception
{
    virtual const char* what() const throw()
    {
        return "My Exception";
    }
}

// empty classes may also be used as exceptions
class MyException;


try 
{
     throw InvalidId;
} 
catch (exception& e) 
{
    cout << e.what() << endl;
} 
catch(...)
{
    cout << "unknown exception occurred" << endl;
}

multiple catches

try {

} catch( MyExcept, const& e ){

} catch( MyOtherExcept, const& e ){

}

re-throw exceptions

try {

} catch( MyExcept, const& e ){
	throw;									// throw without arguments re-throws the last exception
}
