      java.security.Permission

All Implemented Interfaces:
  java.io.Serializable, java.security.Guard

    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. 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.
