Examples of org.eclipse.persistence.queries.ReadObjectQuery

org.eclipse.persistence.queries.ReadObjectQuery

Purpose: Concrete class for all read queries involving a single object.

Responsibilities: Return a single object for the query. Implements the inheritance feature when dealing with abstract descriptors. @author Yvon Lavoie @since TOPLink/Java 1.0
