+<div class="method">
+ <code class="details" id="list">list(topic, pageSize=None, pageToken=None, x__xgafv=None)</code>
+ <pre>Lists the names of the snapshots on this topic. Snapshots are used in
+<a href="https://cloud.google.com/pubsub/docs/replay-overview">Seek</a>
+operations, which allow

+acknowledgment state of messages in an existing subscription to the state
+captured by a snapshot.

+Args:
+ topic: string, The name of the topic that snapshots are attached to.
+Format is `projects/{project}/topics/{topic}`. (required)
+ pageSize: integer, Maximum number of snapshot names to return.
+ pageToken: string, The value returned by the last `ListTopicSnapshotsResponse`; indicates
+that this is a continuation of a prior `ListTopicSnapshots` call, and
+that the system should return the next page of data.
+ x__xgafv: string, V1 error format.
+ Allowed values
+ 1 - v1 error format
+ 2 - v2 error format
+
+Returns:
+ An object of the form:
+
+ { # Response for the `ListTopicSnapshots` method.
+ "nextPageToken": "A String", # If not empty, indicates that there may be more snapshots that match
+ # the request; this value should be passed in a new
+ # `ListTopicSnapshotsRequest` to get more snapshots.
+ "snapshots": [ # The names of the snapshots that match the request.
+ "A String",
+ ],
+ }</pre>
+</div>

+Args:
+ previous_request: The request for the previous page. (required)
+ previous_response: The response from the request for the previous page. (required)

+Returns:
+ A request object that you can call 'execute()' on to request the next
+ page. Returns None if there are no more items in the collection.
