  • Field Details

    • rtmax

      public long rtmax
      The maximum size in bytes of a READ request supported by the server. Any READ with a number greater than rtmax will result in a short read of rtmax bytes or less.

    • rtpref

      public long rtpref
      The preferred size of a READ request. This should be the same as rtmax unless there is a clear benefit in performance or efficiency.

    • rtmult

      public long rtmult
      The suggested multiple for the size of a READ request.

    • wtmax

      public long wtmax
      The maximum size of a WRITE request supported by the server. In general, the client is limited by wtmax since there is no guarantee that a server can handle a larger write. Any WRITE with a count greater than wtmax will result in a short write of at most wtmax bytes.

    • wtpref

      public long wtpref
      The preferred size of a WRITE request. This should be the same as wtmax unless there is a clear benefit in performance or efficiency.

    • wtmult

      public long wtmult
      The suggested multiple for the size of a WRITE request.

    • dtpref

      public long dtpref
      The preferred size of a READDIR request.

    • maxfilesize

      public long maxfilesize
      The maximum size of a file on the file system.

    • time_delta

      public NfsTime time_delta
      The server time granularity. When setting a file time using SETATTR, the server guarantees only to preserve times to this accuracy. If this is {0, 1}, the server can support nanosecond times, {0, 1000000} denotes millisecond precision, and {1, 0} indicates that times are accurate only to the nearest second.

    • properties

      public long properties
      A bit mask of file system properties. The following values are defined: 
      FSF_LINK = 0x0001
    If this bit is 1 (TRUE), the file system supports
    hard links.
FSF_SYMLINK = 0x0002
    If this bit is 1 (TRUE), the file system supports
    symbolic links.
FSF_HOMOGENEOUS = 0x0008
    If this bit is 1 (TRUE), the information returned by
    PATHCONF is identical for every file and directory
    in the file system. If it is 0 (FALSE), the client
    should retrieve PATHCONF information for each file
    and directory as required.
FSF_CANSETTIME = 0x0010
    If this bit is 1 (TRUE), the server will set the
    times for a file via SETATTR if requested (to the
    accuracy indicated by time_delta). If it is 0
    (FALSE), the server cannot set times as requested.
