com.hp.util.dao.query.DaoUpdateDependentQuery<P,Q,E>

Type Parameters:

P - type of the persistent object.

Q - type of the transport object with a reference to the owner's id.

E - type of the owner persistent object and owner transport object id. This type should be immutable. It is critical this type implements equals() and hashCode() correctly.
