[PS 1.7.7] Overriding a module class used by another class

[fedesib]

Hi everybody,

I know that to override the main class of a module I should achieve something like this (simplified):

ROOT/override/modules/[module]/[module].php

But I need to override a class called by [module].php and included via another file (not directly defined in [module].php

 

In detail I would like to override the class MySQL.php which is defined in mystore/modules/ps_facetedsearch/src/Adapter/MySQL.php

The same question was also asked here: https://stackoverflow.com/questions/66710560/how-to-override-prestshop-1-7-7-module-classes

But with not answer. It is possible?

Thank you for your time,
Federica
