public final class JDOPermission
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. |
