Adobe AD0-E717 Exam - Topic 8 Question 54 Discussion

Actual exam question for Adobe's AD0-E717 exam
Question #: 54
Topic #: 8
[All AD0-E717 Questions]

A developer found a bug inside a private method of a third party module class. How can the developer override the method?

Show Suggested Answer Hide Answer
Suggested Answer: B

To override a private method in a third-party module class, the most effective approach is to use a preference. This involves creating a custom class with the corrected logic and then defining this class as a preference for the original one in the di.xml file. Plugins cannot be used to override private methods, final methods, final classes, or classes created without dependency injection. Therefore, the preference mechanism, which allows for the substitution of the entire class, becomes the viable method to override a private method and modify its behavior.

Wait, can you really override third-party methods like that?

Option B, because who doesn't love a good ol' di.xml override? It's the developer's version of a magic trick!

Option A seems like a hack. I'd rather not touch the preferences.xml if I can avoid it.

I remember that creating a plugin is a common way to modify behavior, especially with the "after" method. That might be the best choice here.

I’m a bit confused about the difference between preferences.xml and di.xml. I thought both could be used for overriding, but I can't recall the specifics.

I feel like we practiced a similar question where we had to override a method. I think the plugin option might be the right approach here.

I agree, Option B is the cleanest solution. Modifying the third-party code directly is a big no-no.

Option C sounds like a lot of work. Why not just create a custom class and override the method? Simple and effective.

I think I remember something about using a custom class, but I'm not sure if it's in preferences.xml or di.xml.

Overriding a private method can be tricky, but I believe option B is the cleanest solution. Creating a custom class and defining it as a preference in the di.xml file should allow me to replace the original implementation without too much hassle.

I think the key here is to create a custom class with the corrected logic. From there, it seems like defining it as a preference in either the preferences.xml or the di.xml file would work. I'll need to double-check the specifics, but that's the general strategy I'm leaning towards.

Option C sounds interesting, but I'm not sure I fully understand how to implement the "after" method in a plugin. I'll need to do some research on that approach.

Hmm, I'm a bit confused on the best way to approach this. Should I be looking at the preferences.xml or the di.xml file? I'm not sure which one would be the right place to define the custom class.
