fcppt::exception Class Reference

Detailed Description

The base class for all exceptions.

fcppt::exception is a wrapper around an exception that uses fcppt::string to store the error message. Note that you will have to use fcppt::exception::string to obtain the string. If you use what(), which is only provided for compatibility with std::exception, nothing useful will be returned. The reason behind this is that a string conversion itself can result in exceptions being thrown. That is why what() does not try to convert from fcppt::string to std::string.
