Adobe AD0-E704 Exam - Topic 11 Question 52 Discussion

Suppose there are 3 classes: Class A, B and C. Class C have dependecy of Class A You need to overrride/change an argument of class A, create an object of it and inject in Class B in such a way that it should not affect the class C. What should be the magento standard way to do this:
B) In module's etc/config.xml, define virtualType node to override argument and create a subclass of A. Then use type node to pass the subclass A object into class B. and C) In module's etc/system.xml, define virtualType node to override argument and create a subclass of A. Then use type node to pass the subclass A object into class B.
A) In module's etc/di.xml, define virtualType node to override argument and create a subclass of A. Then use type node to pass the subclass A object into class B.
D) In module's etc/menu.xml, define virtualType node to override argument and create a subclass of A. Then use type node to pass the subclass A object into class B.

I'm a bit confused about the different XML files. Is system.xml ever used for dependency injection?

I remember practicing a similar question where we had to override a class, and I think it was definitely in di.xml, not config.xml.

I think we need to use di.xml for dependency injection, but I'm not entirely sure about the specifics of virtual types.

This seems straightforward enough. I'll just need to review the Magento documentation on dependency injection and make sure I understand how to properly use the virtualType and type nodes to achieve the desired result. I'm confident I can handle this.

Okay, I think I've got this. The standard way is to use the di.xml file to define the virtualType node, override the argument, and then inject the subclass into Class B. That way, Class C remains unaffected. I'll make sure to implement this carefully.

Hmm, I'm a bit confused on the specifics here. I know we need to use a virtualType node, but I'm not sure if that goes in the di.xml, config.xml, or somewhere else. I'll have to double-check the Magento best practices.

This looks like a tricky one. I'll need to carefully review the Magento dependency injection documentation to make sure I understand the proper way to override an argument and inject it into another class without affecting a third class.

A is definitely the way to go. I can't believe anyone would think to use config.xml, system.xml, or menu.xml for this. That would be like trying to change your oil in the microwave.
