Class PersistentFactory

java.lang.Object
  org.wamblee.persistence.PersistentFactory

public class PersistentFactory
extends java.lang.Object

Factory which creates a Persistent object for a given entity for interfacing with the primary key and version of the entity. This utility only treats primary keys and fields that are annotated with @Id and @Version. In case ORM files are used for the definition of primary key and or version, then those fields are ignored.
