Examples of org.jpox.store.rdbms.request.FetchRequest

org.jpox.store.rdbms.request.FetchRequest
Class to retrieve a series of fields for an object of a class from the datastore. All fields are retrieved in a single SELECT, selecting a candidate table (the most derived table for which a field is required), and INNER JOINs to all superclass tables that are also required.
Any surrogate version stored in this table will be fetched *if* the object being updated doesnt already have a value for it. If the caller wants the surrogate version to be updated then they should nullify the "transactional" version before calling.
