Class DetachedCriteria

  • All Implemented Interfaces:
    Serializable, CriteriaSpecification
    public class DetachedCriteria
extends Object
implements CriteriaSpecification, Serializable
    Models a detached form of a Criteria (not associated with a Session). Some applications need to create criteria queries in "detached mode", where the Hibernate Session is not available. Applications would create a DetachableCriteria to describe the query, and then later associated it with a Session to obtain the "executable" Criteria: DetachedCriteria detached = new DetachedCriteria(); ... Criteria criteria = detached.getExecutableCriteria( session ); ... criteria.list(); All methods have the same semantics and behavior as the corresponding methods of the Criteria interface.
