listReleaseLabels method

Future<ListReleaseLabelsOutput> listReleaseLabels({ ReleaseLabelFilter? filters, int? maxResults, String? nextToken, })

Retrieves release labels of Amazon EMR services in the Region where the API is called.

May throw InternalServerException. May throw InvalidRequestException.

Parameter filters : Filters the results of the request. Prefix specifies the prefix of release labels to return. Application specifies the application (with/without version) of release labels to return.

Parameter maxResults : Defines the maximum number of release labels to return in a single response. The default is 100.

Parameter nextToken : Specifies the next page of results. If NextToken is not specified, which is usually the case for the first request of ListReleaseLabels, the first page of results are determined by other filtering parameters or by the latest version. The ListReleaseLabels request fails if the identity (Amazon Web Services account ID) and all filtering parameters are different from the original request, or if the NextToken is expired or tampered with.

Implementation

Future<ListReleaseLabelsOutput> listReleaseLabels({
  ReleaseLabelFilter? filters,
  int? maxResults,
  String? nextToken,
}) async {
  _s.validateNumRange(
    'maxResults',
    maxResults,
    1,
    100,
  );
  final headers = <String, String>{
    'Content-Type': 'application/x-amz-json-1.1',
    'X-Amz-Target': 'ElasticMapReduce.ListReleaseLabels'
  };
  final jsonResponse = await _protocol.send(
    method: 'POST',
    requestUri: '/',
    exceptionFnMap: _exceptionFns,
    // TODO queryParams
    headers: headers,
    payload: {
      if (filters != null) 'Filters': filters,
      if (maxResults != null) 'MaxResults': maxResults,
      if (nextToken != null) 'NextToken': nextToken,
    },
  );

  return ListReleaseLabelsOutput.fromJson(jsonResponse.body);
