What is DetachedCriteria in Hibernate ?

Ref:- https://docs.jboss.org/hibernate/orm/3.5/api/org/hibernate/criterion/DetachedCriteria.html

public class DetachedCriteria
extends Object
implements CriteriaSpecification, Serializable

Some applications need to create criteria queries in "detached mode", where the Hibernate session is not available. This class may be instantiated anywhere, and then a Criteria may be obtained by passing a session to getExecutableCriteria(). All methods have the same semantics and behavior as the corresponding methods of the Criteria interface.
