Exception

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.

Folder structure

• src contains the source code (Exception class).

Including and compiling Exception in a project

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

Usage

Basic usage

1. 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();

2. Catch the exception, and (e.g.) print the Exception-Message with all information:

catch ( Exception & e )
{
    std::cerr << "Exception: " << e.what() << std::endl;
}

Implementing new Exception-Types based on Exception

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();
    }
};
