What does "granular inheritance" mean?

Question

Programming

In the process of work, I heard from a high-ranking Solution Architect a phrase containing the phrase "granularity of inheritance". Can someone give a short explanation of what is the point?

Answer 1

Perhaps, this means inheritance in the form of not the whole class, but only its separate loosely coupled parts. traits concept.

Answer 2

In programming, the terms "fine-grained" and "coarse-grained" are sometimes used to describe systems, usually to reflect the degree of connectivity between system components. In the English part of the Internet, I can’t remember a stable term similar to “granularity of inheritance”, moreover, such a phrase seems strange to me, because inheritance is the type of connection in which the system is the most tightly coupled (least granular).
