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.

Member Function Documentation

◆ operator=() [1/2]

FCPPT_DETAIL_SYMBOL exception & fcppt::exception::operator= ( exception &&  )

◆ operator=() [2/2]

FCPPT_DETAIL_SYMBOL exception & fcppt::exception::operator= ( exception const &  )

◆ string()

FCPPT_DETAIL_SYMBOL fcppt::string const & fcppt::exception::string ( ) const

Returns the error message.

Use this function to print the error message instead of what()

◆ what()

FCPPT_DETAIL_SYMBOL char const * fcppt::exception::what ( ) const

Returns a generic error.

This function's purpose is to provide compatibility with std::exception. It returns nothing useful.
