 <DD>Initialize the given state manager. The object id of the
  state manager will be set, and the state manager's metadata be set to
  the class of the instance to load, or possibly one of its superclasses.
  Initialization involves first calling the
  <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html#initialize(java.lang.Class, org.apache.openjpa.kernel.PCState)"><CODE>OpenJPAStateManager.initialize(java.lang.Class, org.apache.openjpa.kernel.PCState)</CODE></A> method with
  a new instance of the correct type constructed with the
  <A HREF="../../../../org/apache/openjpa/enhance/PCRegistry.html#newInstance(java.lang.Class, org.apache.openjpa.enhance.StateManager, boolean)"><CODE>PCRegistry.newInstance(Class,
  org.apache.openjpa.enhance.StateManager, boolean)</CODE></A> method
  (this will reset the state manager's metadata if the actual type was a
  subclass). After instance initialization, load any the fields for the
  given fetch configuration that can be efficiently retrieved. If any of
  the configured fields are not loaded in this method, they will be
  loaded with a subsequent call to <A HREF="../../../../org/apache/openjpa/kernel/StoreManager.html#load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)"><CODE>StoreManager.load(org.apache.openjpa.kernel.OpenJPAStateManager, java.util.BitSet, org.apache.openjpa.kernel.FetchConfiguration, int, java.lang.Object)</CODE></A>. If this method is
  called during a data store transaction, the instance's database record

 <DD>Load the given state manager.
  Note that any collection or map types loaded into the state manager
  will be proxied with the correct type; therefore the store manager
  does not have to load the same concrete collection/map types as the
  instance declares. However, array types must be consistent with the
  array type stored by the persistence capable instance. If this method
  is called during a data store transaction, the instance should be
  locked. If the given state manager does not have its version set
  already, version information can be loaded if desired through the
  <A HREF="../../../../org/apache/openjpa/kernel/OpenJPAStateManager.html#setVersion(java.lang.Object)"><CODE>OpenJPAStateManager.setVersion(java.lang.Object)</CODE></A> method.
