public interface ObjectId extends Serializable
A portable global identifier for persistent objects. ObjectId can be temporary (used for transient or new uncommitted objects) or permanent (used for objects that have been already stored in DB).
A temporary ObjectId stores object entity name and a pseudo-unique binary key; permanent id stores a map of values from an external persistent store (aka "primary key").
