And one more question - what about user-defined exceptions?
Suppose I have following code from library which I cannot modify:
namespace faif
{
class FaifException : public std::exception {
public:
FaifException(){}
virtual ~FaifException() throw() {}
virtual const char *what() const throw() { return
"FaifException"; }
virtual std::ostream& print(std::ostream& os) const throw();
};
class UserBreakException : public FaifException {
public:
UserBreakException(){}
virtual ~UserBreakException() throw() {}
virtual const char *what() const throw(){ return "UserBreak
exception"; }
virtual std::ostream& print(std::ostream& os) const throw();
};
(...)
}
This causes following warnings:
WARNING: char const * faif::UserBreakException::what() const [member function]
> warning W1046: The virtual function was declared with empty throw. Adding the
> ability to override the function from Python breaks the exception
> specification. The function wrapper can throw any exception. In case of
> exception in run-time, the behaviour of the program is undefined!
WARNING: std::ostream & faif::UserBreakException::print(std::ostream &
os) const [member function]
> warning W1049: This method could not be overriden in Python - method returns
> reference to local variable!
WARNING: std::ostream & faif::UserBreakException::print(std::ostream &
os) const [member function]
> warning W1046: The virtual function was declared with empty throw. Adding the
> ability to override the function from Python breaks the exception
> specification. The function wrapper can throw any exception. In case of
> exception in run-time, the behaviour of the program is undefined!
Should I exclude this declarations or there is another solution? (I am
not sure excluding it may be called 'solution'...)
BTW - Why warnings doesn't provide information form what header file
particular warning was generated?
BTW2 - How to exclude the whole class from generation?
