DESCRIPTION

       Definition for common classes and constants

CLASSES

   class SparseFile(baseobj.BaseObj)
       SparseFile object

       SparseFile() -> New sparse file object

       Usage:
           # Create definition for a sparse file of size 10000 having
           # two holes of size 1000 at offsets 3000 and 6000
           x = SparseFile("/mnt/t/file1", 10000, [3000, 6000], 1000)

           # Object attributes defined after creation using the above
           # sample data:

           # endhole: set to True if the file ends with a hole
           # Above example ends with data so,
           # x.endhole = False

           # data_offsets: list of data segment offsets
           # x.data_offsets = [0, 4000, 7000]

           # hole_offsets: list of hole segment offsets including the
           #   implicit hole at the end of the file
           # x.hole_offsets = [3000, 6000, 10000]

           # sparse_data: list of data/hole segments, each item in the list
           #   has the following format [offset, size, type]
           # x.sparse_data = [[0, 3000, 1], [3000, 1000, 0], [4000, 2000, 1],
           #                  [6000, 1000, 0], [7000, 3000, 1]]

       Methods defined here:
       ---------------------

       __init__(self, absfile, file_size, hole_list, hole_size)
       Create sparse file object definition, the file is not created
       just the object. Object attributes are defined which makes it
       easy to create the actual file.

              absfile:
                     Absolute path name of file

              file_size:
                     Total size of sparse file

              hole_list:
                     List of hole offsets

              hole_size:
                     Size for each hole

FUNCTIONS

       split_path(path)
       Return list of components in path
