Summarizing the Basic Implementation

00:00 So let me walk you through the basic implementation, referring back to the graphic we had during the introduction. So we have the client who uses an interface, which is serialize_song() and data_format, to speak or communicate with the creator and a creator is the internal function _get_serializer(). The creator is supposed to call a factory, which it doesn’t do very clearly right now.

00:26 And that factory creates the products which are the internal functions, _serialize_to_json() and _serialize_to_xml().

00:36 So these are the components of the basic implementation.

00:42 Looking at this solution and this structure, though, there are some potential improvements. For example, we really should work towards a clearly-defined factory method, which we haven’t done yet.

00:54 Product classes would probably be useful instead of functions. Working with classes is more object-oriented, and it allows us to have some more flexibility and better structure as we will see in the following examples.

01:09 Same thing for the creator. We could have a class instead of a function, which again would help with structure and with functionality. So in general, yes, we could have more flexibility and a better structure, and you’ll be implementing all those improvements and more actually in the advanced implementation of the Factory Method in the next lessons.
