    • copy

      <Y> CriteriaBuilder<Y> copy​(Class<Y> resultClass)
      Description copied from interface: FullQueryBuilder
      Copies this query builder into a new one, using it's projection as an overridable default.
      Specified by:
      copy in interface FullQueryBuilder<T,​CriteriaBuilder<T>>
      Type Parameters:
      Y - The type of the result class
      Parameters:
      resultClass - The result class of the query
      Returns:
      A new query builder

    • selectNew

      <Y> SelectObjectBuilder<CriteriaBuilder<Y>> selectNew​(Class<Y> clazz)
      Description copied from interface: FullQueryBuilder
      Starts a SelectObjectBuilder for the given class. The types of the parameter arguments used in the SelectObjectBuilder must match a constructor of the given class.
      Specified by:
      selectNew in interface FullQueryBuilder<T,​CriteriaBuilder<T>>
      Type Parameters:
      Y - The new query result type specified by the given class
      Parameters:
      clazz - The class which should be used for the select new select clause
      Returns:
      The select object builder for the given class

    • selectNew

      <Y> CriteriaBuilder<Y> selectNew​(ObjectBuilder<Y> builder)
      Description copied from interface: FullQueryBuilder
      Applies the given object builder to this query. The object builder provides the select clauses and is used to transform the result set tuples.
      Specified by:
      selectNew in interface FullQueryBuilder<T,​CriteriaBuilder<T>>
      Type Parameters:
      Y - The new query result type specified by the given class
      Parameters:
      builder - The object builder which transforms the result set into objects of type Y
      Returns:
      The query builder for chaining calls
