Examples of ObjectIdQuery

org.apache.cayenne.query.ObjectIdQuery
A query that matches zero or one object or data row corresponding to the ObjectId. Used internally by Cayenne to lookup objects by id. Notice that cache policies of ObjectIdQuery are different from generic {@link QueryMetadata} cache policies.ObjectIdQuery is special - it is the only query that can be done against Cayenne main cache, thus cache handling is significantly different from all other of the queries. @since 1.2 @author Andrus Adamchik
