Summary of entries of Classes for batch.
Classes
BatchServiceAsyncClient

ListJobsAsyncPager
A pager for iterating through list_jobs requests.
This class thinly wraps an initial
ListJobsResponse object, and
provides an __aiter__ method to iterate through its
jobs field.
If there are more pages, the __aiter__ method will make additional
ListJobs requests and continue to iterate
through the jobs field on the
corresponding responses.
All the usual ListJobsResponse attributes are available on the pager. If multiple requests are made, only the most recent response is retained, and thus used for attribute lookup.
