Examples of Persistent

br.com.procempa.modus.entity.Persistent
br.jus.tjrn.arq.persistence.Persistent
Persistent define uma entidade persistível. Uma classe de domínio.
As classes que a implementarem deverão fornecer um identificador padrão e um label. @author Gewton Jhames @author Misael Barreto @author Rafael Pinto
civquest.io.Persistent
com.antlersoft.odb.Persistent
Interface that defines the only method objects need to support to be persistent. Obviously, we assume that the objects are also serializable. It is also possible to implement this interface so persistence breaks, but you would have to avoid the obvious implementation. The first class in the class hierarchy that is persistent should contain a private transient PersistentImpl member, which this class will return. It should initialize this member when constructed by calling its empty constructor. Classes derived from a Persistent class won't have to do anything.
de.iritgo.aktera.persist.Persistent
A persistent object. Your application classes should *not* normally directly implement this interface, but should instead request instances from the current PersistentFactory. Only implementation classes for the persistence service implement this interface directly. If you prefer to do "bean-like" objects as your persistent classes, see AbstractPersistent instead.
org.apache.cayenne.Persistent
Defines minimal API of an object that can be persisted via Cayenne. @since 1.2
org.apache.gora.persistency.Persistent
Objects that are persisted by Gora implements this interface.
