Method Detail

  public abstract boolean timeout(java.lang.String server,

                                  int wait)

  Called when an NFS request has timed out The RPC code will retransmit NFS requests until the server responds. The initial retransmission timeout is set by the NFS code and increases exponentially with each retransmission until an upper bound of 30 seconds is reached, e.g. timeouts will be 1, 2, 4, 8, 16, 30, 30, ... sec.

  An instance of the NfsHandler class is registered with the setHandler method of the NFS XFileExtensionAccessor.
