"""A pager for iterating through ``list_operations`` requests.
This class thinly wraps an initial
:class:`google.longrunning.operations_pb2.ListOperationsResponse` object, and
provides an ``__iter__`` method to iterate through its
``operations`` field.
If there are more pages, the ``__iter__`` method will make additional
``ListOperations`` requests and continue to iterate
through the ``operations`` field on the
corresponding responses.
All the usual :class:`google.longrunning.operations_pb2.ListOperationsResponse`
attributes are available on the pager. If multiple requests are made, only
the most recent response is retained, and thus used for attribute lookup.
