Parameters

Type	Name	Description
protos. google.spanner.v1.IListSessionsRequest	request	The request object that will be sent.
CallOptions	options	Call options. See CallOptions for more details.

Returns

Type	Description
AsyncIterable <protos. google.spanner.v1.ISession >	{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [Session]. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

CallOptions	options	Call options. See CallOptions for more details.

Returns

Type	Description
Transform	{Stream} An object stream which emits an object representing [Session] on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using `listSessionsAsync()` method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.
