    • checkPermission

      public static void checkPermission(Permission perm) throws AccessControlException
      Deprecated, for removal: This API element is subject to removal in a future version.
      Throws AccessControlException
      Parameters:
      perm - is ignored
      Throws:
      AccessControlException - is always thrown

    • getContext

      public static AccessControlContext getContext()
      Deprecated, for removal: This API element is subject to removal in a future version.
      Returns:
      an AccessControlContext with no permissions

    • doPrivileged

      public static <T> T doPrivileged(PrivilegedAction<T> action)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Performs the privileged action specified by action.

      When permission checks are made, if the permission has been granted by all frames below and including the one representing the call to this method, then the permission is granted. In other words, the check stops here. Any unchecked exception generated by this method will propagate up the chain.

      Type Parameters:
      T - the type of value returned by PrivilegedAction.run
      Parameters:
      action - The PrivilegedAction to performed
      Returns:
      the result of the PrivilegedAction
      Throws:
      NullPointerException - if action is null
      See Also:

    • doPrivileged

      public static <T> T doPrivileged(PrivilegedAction<T> action, AccessControlContext context)
      Deprecated, for removal: This API element is subject to removal in a future version.
      Performs the privileged action specified by action.

      When permission checks are made, if the permission has been granted by all frames below and including the one representing the call to this method, then the permission is granted iff it is granted by the AccessControlContext context. In other words, no more checking of the current stack is performed. Instead, the passed in context is checked. Any unchecked exception generated by this method will propagate up the chain.

      Type Parameters:
      T - the type of value returned by PrivilegedAction.run
      Parameters:
      action - The PrivilegedAction to performed
      context - The AccessControlContext to check
      Returns:
      the result of the PrivilegedAction
      Throws:
      NullPointerException - if action is null

      Performs the privileged action specified by action.

      When permission checks are made, if the permission has been granted by all frames below and including the one representing the call to this method, then the permission is granted. In other words, the check stops here. Any unchecked exception generated by this method will propagate up the chain. However, checked exceptions will be caught an re-thrown as PrivilegedActionExceptions

      Type Parameters:
      T - the type of value returned by PrivilegedExceptionAction.run
      Parameters:
      action - The PrivilegedExceptionAction to performed
      Returns:
      the result of the PrivilegedExceptionAction
      Throws:
      PrivilegedActionException - when a checked exception occurs when performing the action NullPointerException if action is null
