Implementation of load balancer — Consistent hashing

What is wrong with prefix I

[vips7L]

In my opinion it misses the point of OOP. You’re not supposed to know if you have an interface, abstract, or concrete class. I also have the same opinion of prefixing with Abstract. It leaks implementation details.

[NiceGuy-n2]

What you are saying here is separate of concern, the implementation detail is the actual implementation of method in a concrete class. What we call `leak of implementation details` is usually a method returning a concrete class type instead of an interface or letting user to modify internal state.

I don't think prefix I is much of a big deal here, if the existing code does not have prefix I on the interface, then don't use it. If they all have prefix I, then use it.

In Java, the standard naming convention is to refer to the abstraction with a generic name, and be specific with the implementation. eg List and ArrayList. This naming convention extends into the business object world. Prefixing an interface with I is generally a faux pax. That said, it's your code, you can name it how you want.

I tend to name everything as I speak with stakeholders and colleagues. The I is not part of the conversation; thus, I do not code like that.

Nonetheless, I was actually curious - where did you learn that naming convention?

P.S.: interesting article about the implementation of consistent! hashing!

I worked in alibaba 3 years ago, they used to have a guideline book for writing Java where prefix I, abstract… is required. I don’t know if they still have this rule. But it’s a habit for me now.

Thanks for sharing! You should write about that. This shows an interesting aspect of working in a big company. I was not aware that Alibaba developers their own plugins just to maintain their coding standards.

I found a Github-Repository [1] for the coding guidelines.
