    Description copied from interface: OpenJPAStateManager
    
    Create a new hollow proxy instance for the given field. In cases where the field externalizes to an SCO but is declared something else, the returned object may not implement Proxy. In all other cases, this method delegates to the system ProxyManager with the correct field information. The returned proxy's owner is unset so that modifications to the proxy will not be tracked while its state is initialized. Calling OpenJPAStateManager.storeField(int, java.lang.Object) or OpenJPAStateManager.store(int, java.lang.Object) will set the proxy's owner automatically.

  - setObjectId
```
public void setObjectId(Object oid)
```
    Description copied from interface: OpenJPAStateManager
    
    Set the object id for the managed instance. Some back ends may not be able to assign a permanent oid until flush. Do not call this method on application identity instances; changing the primary key fields of application identity objects through the storeXXXField methods will automatically change the oid.
    
    Specified by:
    
    setObjectId in interface OpenJPAStateManager
  - assignObjectId
```
public boolean assignObjectId(boolean flush)
```
    Description copied from interface: OpenJPAStateManager

    Specified by:
    
    assignObjectId in interface OpenJPAStateManager

  - setVersion
```
public void setVersion(Object version)
```
    Description copied from interface: OpenJPAStateManager
    
    Set the version indicator for this instance, as loaded from the data store. This method is used by the StoreManager when loading instance data. On rollback, the version will be rolled back to this value. Version objects should be serializable and should not require vendor-specific classes, because they are transferred to detached objects.
    
    Specified by:
    
    setVersion in interface OpenJPAStateManager
  - setNextVersion
```
public void setNextVersion(Object version)
```
    Description copied from interface: OpenJPAStateManager

```
