Examples of org.hibernate.criterion.Criterion

org.hibernate.criterion.Criterion
An object-oriented representation of a query criterion that may be used as a restriction in a Criteria query. Built-in criterion types are provided by the Restrictions factory class. This interface might be implemented by application classes that define custom restriction criteria. @see Restrictions @see Criteria @author Gavin King
