Initializes the class, it is not meant to be instantiated directly, but rather through one of the available factory methods. Still, it can be instantiated directly if the user wants to use a custom Config class.

Parameters:¶

config : Config¶

The Config object to use. This object contains all the configuration options that the user can set, and the QueryHandler class will use these options as they are needed throughout the operation of the class. It is recommended that the user uses the factory methods to create a new instance of the class instead of instantiating it directly, as the factory methods will automatically create a Config object for the user based on the instantiation method they prefer and pass it to the constructor.
