Something confusing me.

Hi @thombergs ,
A query here, in the book "Get Your Hands Dirty ond Clean Architecture", you have used the term/word UseCase, for the stuff in ports/in interface. But at many places, I have seen use case is not interface but implementation of input port interface.
So should the UseCase be considered here as port (interface) and application.domain.service as its implementation.
Like, in general
Input port >>>implemented by >>> UseCase class
But you termed it as
UseCase >>>implemented by >>> application.domain.service

Please reply, as its getting confused when compared with other learning stuff on internet.
Thank you.

Regards,
Nishant
