JDO Annotations for Classes

JDO supports two modes of persistable classes that can be set by the following annotations:

• javax.jdo.annotations.PersistenceCapable
• javax.jdo.annotations.EmbeddedOnly

Non persistable classes that should be enhanced (because of accessing persistent fields of other classes directly) can be marked with:

• javax.jdo.annotations.PersistenceAware

The identity mode of persistence capable classes can be specified by using:

• javax.jdo.annotations.DatastoreIdentity
• javax.jdo.annotations.IdentityType
