Class NfsAccessResponse

Direct Known Subclasses:
Nfs3AccessResponse
public class NfsAccessResponse extends NfsResponseBase
The response, as specified by RFC 1813 (https://tools.ietf.org/html/rfc1813).

Procedure ACCESS determines the access rights that a user, as identified by the credentials in the request, has with respect to a file system object. The client encodes the set of permissions that are to be checked in a bit mask. The server checks the permissions encoded in the bit mask. A status of NFS3_OK is returned along with a bit mask encoded with the permissions that the client is allowed.

The results of this procedure are necessarily advisory in nature. That is, a return status of NFS3_OK and the appropriate bit set in the bit mask does not imply that such access will be allowed to the file system object in the future, as access rights can be revoked by the server at any time.
