25 class ResultSet(list):
26 """
27 The ResultSet is used to pass results back from the Amazon services
28 to the client. It is light wrapper around Python's :py:class:`list` class,
29 with some additional methods for parsing XML results from AWS.
30 Because I don't really want any dependencies on external libraries,
31 I'm using the standard SAX parser that comes with Python. The good news is
32 that it's quite fast and efficient but it makes some things rather
33 difficult.
34
35 You can pass in, as the marker_elem parameter, a list of tuples.
36 Each tuple contains a string as the first element which represents
37 the XML element that the resultset needs to be on the lookout for
38 and a Python class as the second element of the tuple. Each time the
39 specified element is found in the XML, a new instance of the class
40 will be created and popped onto the stack.
41
42 :ivar str next_token: A hash used to assist in paging through very long
43 result sets. In most cases, passing this value to certain methods
44 will give you another 'page' of results.
