How else we can use pre_body method and post_body method in a sequence apart from raising and dropping objections?

In reply to cgales:
Thanks cgales!
In some of the examples, i have seen people comparing starting_phase != null and then raising the objection. I didn’t get the idea here, what is in starting_phase and what we are trying to compare with null. Could you pls elaborate on it a little.

E.g https://verificationacademy.com/forums/uvm/how-start-sequence/s

In this example, he’s comparing starting phase != null in the pre_body task.
