Exception is a very minimalistic exception base-class, which allows to use exceptions which contain a little bit more information and are a bit more user-friendly (supports Strings) than the standard exception-class.
It's intended to be used as a base class for other Exception-Types.
srccontains the source code (Exceptionclass).
In order to use Exception, <path>/Exception/src/Exception.hpp needs to be included.
In order to compile Exception, following files need to be compiled and linked:
<path>/Exception/src/Exception.hpp
- Throw a new
Exception-Object whilst using one of the following constructors:
Exception( std::string file, int line, std::string message );
Exception( std::string file, int line );
Exception( std::string message );
Exception();
- Catch the exception, and (e.g.) print the Exception-Message with all information:
catch ( Exception & e )
{
std::cerr << "Exception: " << e.what() << std::endl;
}
Exception can simply be used as a base class for other exceptions. In order to do this, Exception can be inherited. To also inherit all overloaded constructors using Exception::Exception; should be used in the header of a public-section.
Example for a new Exception-based class:
#include "../dependencies/Exception/src/Exception.hpp"
class SampleException : private Exception
{
public:
using Exception::Exception; // This line is needed so we can simply inherit all overloaded constructors from the baseclass.
std::string what() throw()
{
return "SampleException: " + getMsg();
}
};
