The JDOPermission
class is for operations that are reserved for JDO
implementations and should not be called by other code. A
JDOPermission
is a named permission and has no
actions. There are two names currently defined. Each named permission
has a corresponding public static final field which contains an instance
of the named permission.
The following table provides a summary description of what each named permission allows, and discusses the risks of granting code the permission.
Permission Target Name | What the Permission Allows | Risks of Allowing this Permission |
---|---|---|
setStateManager |
This allows setting the StateManager for an instance of PersistenceCapable .
The StateManager
has unlimited access to get and set persistent and transactional fields of
the PersistenceCapable instance. |
This is dangerous in that information (possibly confidential) normally unavailable would be accessible to malicious code. |
getMetadata |
This allows getting metadata for any PersistenceCapable class that has
registered with JDOImplHelper . |
This is dangerous in that metadata information (possibly confidential) normally unavailable would be accessible to malicious code. |
manageMetadata |
This allows managing metadata for any PersistenceCapable class that has
registered with JDOImplHelper . |
This is dangerous in that metadata information (possibly confidential) normally unavailable would be manageable (modifiable) by malicious code. |
closePersistenceManagerFactory |
This allows closing a PersistenceManagerFactory ,
thereby releasing resources. |
This is dangerous in that resources bound to the
PersistenceManagerFactory would be releaseable by
malicious code. |
