Understanding custom custom resultset

Hello everyone,, I am going through docs, while reading this : https://docs.phalcon.io/en/3.3/db-model , surely I understand most of the aspect but can anyone explain custom resultset which is added to a model using getResultsetClass() . I would like to see a working practical example if there is any already .

Thanks...
