Complex classes like BaseRepository often do a lot of different things. To break such a class down, we need to identify a cohesive component within that class. A common approach to find such a component is to look for fields/methods that share the same prefixes, or suffixes. You can also have a look at the cohesion graph to spot any un-connected, or weakly-connected components.
Once you have determined the fields that belong together, you can apply the Extract Class refactoring. If the component makes sense as a sub-class, Extract Subclass is also a candidate, and is often faster.
While breaking up the class, it is a good idea to analyze how other classes use BaseRepository, and based on these observations, apply Extract Interface, too.

If you implement
__call
and you know which methods are available, you can improve IDE auto-completion and static analysis by adding a @method annotation to the class.This is often the case, when
__call
is implemented by a parent class and only the child class knows which methods exist:
