A perfect example of the meaningful application of the Factory Design Pattern. I have seen dozens of videos. This is the only one that clearly shows the benefits of the Factory Pattern.

Great video! I was watching one of your other videos explaining abstract factory methods in C#, but halfway through it was marked as private, so I didn't get to see the rest. Will it come back up?

@T0g3ly 3 месяца назад

Hi I’m learning design patterns I like your videos but can you possibly make a video of when I should maybe use factory method vs abstract. I understand there isn’t a simple answer but maybe a “Look for these signs answer”

@campbelltech 3 месяца назад

Thanks for the request. I will consider it.

What do you do if CreditCard has a method GetStatement that returns a CreditCardStatementModel object, but GetStatement for paypal returns a PayPalStatementModel object with different fields? Since methods have the same name but a different return type, you couldn't implement a common interface.

@campbelltech 5 месяцев назад

Hi Kyle, you can introduce a base or abstract StatementModel. Then CreditCardStatementModel and PayPalStatementModel can inherit from or extend StatementModel. Then, let the GetStatement method return StatementModel, and through Polymorphism you can "cast" it back to the concrete types in the concrete classes.

@abdullahbinmamun3803 6 дней назад

In this case we can use abstract class instead of using an interface. which can have an abstract method named "Statement" which will return a statement. other classes like GooglePay, PayPal and CreditCard will override and implement the same "Statement" method but will return different statements. I hope, I explained it correctly.

How does your code promotes open closed principle ?

@campbelltech Год назад

The Factory method allows you to decouple creation logic from your client code. In this way, if you add, for example, a new payment method you only need to add a new class, e.g. ApplePayPayment and add support for it in your factory method. Your client code, which could be your main service code, can then stay exactly the same. In other words, it is closed for modification, but the Factory method makes it open for extension.

@@campbelltech Good answer! 👌

@scotterd 3 месяца назад

@@campbelltech wouldn't use also need to add a new enum called ApplePay and modify the client to call the factory with the new enum?

@NewQuietBear 5 месяцев назад

You violate the open/closed principle. Everytime u have to add a new payment method to the factory and enum.

@campbelltech 5 месяцев назад

The client code, however, remains unchanged and follows the open-closed principle. Many would argue that adding the enums and extending the factory method only, still remain within the boundaries of the open-closed principle. If you want to comply on all levels, you will have to use reflection, possibly compromising on performance.
