What is the use of Hibernate Callback interface?

Can someone please explain what is the use of HibernateCallBack interface?

I have googled something related to this and understood that it will notify the changes made to the persistent objects. Is my understanding correct? Please someone clearly explain me what it does and when to use this interface. I have gone through the internal implementation of hibernate template and observed all the operations performed on persistent objects like save,delete, load etc are using this interface.

A good explanation is appreciable.

Thanks in advance.

I know this does not answer your question directly but don't use HibernateTemplate/HibernateDaoSupport it isn't recommended use the SessionFactory directly.

As a matter of fact as of hibernate 4 its not only not recommended but it has been removed altogether. See the below Jira
https://jira.springsource.org/browse/SPR-8096

Eliminate HibernateTemplate and friends (e.g. HibernateCallback in favor of Spring's more modern 'Native Hibernate DAO' approach



Unless you are using a very old version of hibernate in a legacy application it should be avoided.
