public final class JDOPermission

extends java.security.BasicPermission

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.

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 StateMananger 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.
