What is the difference between `uvm_do_callback and `uvm_do_obj_callback?

In reply to tfitz:

Thanks a lot.
I am trying to provide an interface to the callback class and do certain operations from the callback and
resume my current operation.
However, if I am not wrong callback class doesn’t have the build phase which makes it difficult to use uvm_config_db/factory override.
Correct me if I am wrong.

Thanks.
