This video wraps up the discussion of abstract factory for National credit union. We explain the role of the 'provider' code and how it is used to by the client. Lastly, we cover how the program is executed through the client which is able to generate the correct factory it needs based on input provided.
- [Voiceover] Now that we have all our abstractions…and concretions in place, specifically the…abstract factories and its concretions…and the abstract products and its concretions,…we're ready to create the logic that determines…which factory needs to be returned…dependent on a particular request.…And that's where the provider comes into play,…so if we look in our provider's project,…you'll see a file called credit union factory.…We can open that up and when we expand the code there,…we'll see that we have logic similar to what we've…done with the factory method.…
This again here is the essence of this factory pattern,…this abstract factory pattern,…and it's because we have our if L's condition that…determines which factory is going to be returned,…and that's dependent on whether or not we pass in…the term citi or national in the string.…Moving on to our client, to execute the code,…let's step through what's going on over here,…I simply create a list of account numbers,…one of them will be for citi,…one of them will be for national,…

5/31/2016In this course, developer and technologist Reynald Adolphe explains the purpose and effective use of eight design patterns, including six Gang of Four design patterns and two .NET patterns. Gang of Four patterns fall under three categories: structural, creational, and behavioral. Reynald helps you learn about select patterns from each category. He describes each pattern and demonstrates how programmers can leverage them in real-world applications.
