listen method

Future<ListenResponse> listen (ListenRequest request, String database, { String $fields })

Listens to changes.

request - The metadata request object.

Request parameters:

database - The database name. In the format: projects/{project_id}/databases/{database_id}. Value must have pattern "^projects/^/+/databases/^/+$".

$fields - Selector specifying which fields to include in a partial response.

Completes with a ListenResponse.

Completes with a commons.ApiRequestError if the API endpoint returned an error.

If the used http.Client completes with an error when making a REST call, this method will complete with the same error.

Implementation

async.Future<ListenResponse> listen(
    ListenRequest request, core.String database,
    {core.String $fields}) {
  var _url;
  var _queryParams = new core.Map<core.String, core.List<core.String>>();
  var _uploadMedia;
  var _uploadOptions;
  var _downloadOptions = commons.DownloadOptions.Metadata;
  var _body;

  if (request != null) {
    _body = convert.json.encode((request).toJson());
  }
  if (database == null) {
    throw new core.ArgumentError("Parameter database is required.");
  }
  if ($fields != null) {
    _queryParams["fields"] = [$fields];
  }

  _url = 'v1/' +
      commons.Escaper.ecapeVariableReserved('$database') +
      '/documents:listen';

  var _response = _requester.request(_url, "POST",
      body: _body,
      queryParams: _queryParams,
      uploadOptions: _uploadOptions,
      uploadMedia: _uploadMedia,
      downloadOptions: _downloadOptions);
  return _response.then((data) => new ListenResponse.fromJson(data));
