org.apache.openjpa.persistence.criteria.PathImpl<Z,X>
org.apache.openjpa.persistence.criteria.FromImpl<Z,X>
Z - the parent type of this receiverX - the type represented by this receiverclass FromImpl<Z,X>
Represents a bound type, usually an entity that appears in the from clause, but may also be an embeddable belonging to an entity in the from clause. Serves as a factory for Joins of associations, embeddables and collections belonging to the type, and for Paths of attributes belonging to the type.
