      • extendConfiguration

        public static Config4Class extendConfiguration​(ReflectClass clazz,
                                               Configuration config,
                                               Config4Class classConfig)
        Should create additional configuration, for example through reflection on annotations. - If a valid configuration is passed as classConfig, any additional configuration, if available, should be applied to this object, and this object should be returned. - If classConfig is null and there is no additional configuration, null should be returned. - If classConfig is null and there is additional configuration, this code should create and register a new configuration via config.objectClass(), apply additional configuration there and return this new instance. The reason for this dispatch is to avoid creation of a configuration for a class that doesn't need configuration at all.
        Parameters:
        clazz - The class to be searched for additional configuration information
        config - The global database configuration
        classConfig - A class configuration, if one already exists
        Returns:
        classConfig, if not null, a newly created ObjectClass otherwise.
