I'm new to Hibernate and trying to understand more about the LockModes.

I found below text in book "Java Persistence with Hibernate":

LockMode.READ—Bypass all caches, and perform a version check to verify that the object in memory is the same version that currently exists in the database.

Does that mean, calling session.lock(myObject, LockMode.READ), will refresh my Object state from Database? From "version check" I understand that Hibernate will check the version of myObject with Database, and if there is a difference it will synchronize instance of myObject with that of database. Isn't that correct?
