  • Constructor Details

    • NfsResponseBase

      public NfsResponseBase()
      Create the base class object.

  • Method Details

    • unmarshalling

      public void unmarshalling(Xdr xdr) throws RpcException
      Load this structure from the response data, as specified by RFC 1831 (https://tools.ietf.org/html/rfc1831).
      Overrides:
      unmarshalling in class RpcResponse
      Parameters:
      xdr - The xdr response data.
      Throws:
      RpcException

    • getState

      public int getState()
      Returns the state returned in the response. For details, see RFC 1813 (https://tools.ietf.org/html/rfc1813).

    • toString

      public String toString()
      Overrides:
      toString in class Object

    • getAttributes

      public final NfsGetAttributes getAttributes()
      Returns file system object post-operation attributes. These are provided for many calls. For information on the object to which the attributes refer, or for other details, see RFC 1813 (https://tools.ietf.org/html/rfc1813).

    • getFileHandle

      public final byte[] getFileHandle()
      Returns the file handle for the system object that was created for a successful CREATE, MKDIR, MKNOD, or SYMLINK request, or looked up for a LOOKUP request. This is null for all other requests, and also for failed requests.

    • stateIsOk

      public boolean stateIsOk()
      Check the state returned in the response. For details, see RFC 1813 (https://tools.ietf.org/html/rfc1813).
      Returns:
      true if the state is NFS3_OK, false otherwise

    • unmarshallingAttributes

      protected void unmarshallingAttributes(Xdr xdr)
      Unmarshall the object if it is there. Convenience method for use in subclasses.

    • unmarshallingAttributes

      protected void unmarshallingAttributes(Xdr xdr, boolean force)
      Unmarshall the object if it is there, or skip the existence check if force is true. Convenience method for use in subclasses.
      Parameters:
      force - do not check whether it is there

    • unmarshallingFileHandle

      protected void unmarshallingFileHandle(Xdr xdr)

    • makeNfsGetAttributes

      protected static NfsGetAttributes makeNfsGetAttributes(Xdr xdr)
      Create the object if it is there, return null if it is not. Convenience method for use in subclasses.
      Returns:
      the created object or null

    • makeNfsGetAttributes

      protected static NfsGetAttributes makeNfsGetAttributes(Xdr xdr, boolean force)
