Get calendar events API

A GetCalendarEventsRequest requires a non-null calendar ID. Using the literal _all returns the events for all calendars.

GetCalendarEventsRequest request = new GetCalendarEventsRequest("holidays"); 

The following arguments are optional:

request.setPageParams(new PageParams(10, 20)); 

request.setStart("2018-08-01T00:00:00Z"); 

request.setEnd("2018-08-02T00:00:00Z"); 

request.setJobId("job_1"); 

When executing a GetCalendarEventsRequest in the following manner, the client waits for the GetCalendarEventsResponse to be returned before continuing with code execution:

GetCalendarEventsResponse response = client.machineLearning().getCalendarEvents(request, RequestOptions.DEFAULT);

Synchronous calls may throw an IOException in case of either failing to parse the REST response in the high-level REST client, the request times out or similar cases where there is no response coming back from the server.

In cases where the server returns a 4xx or 5xx error code, the high-level client tries to parse the response body error details instead and then throws a generic ElasticsearchException and adds the original ResponseException as a suppressed exception to it.

Executing a GetCalendarEventsRequest can also be done in an asynchronous fashion so that the client can return directly. Users need to specify how the response or potential failures will be handled by passing the request and a listener to the asynchronous get-calendar-events method:

client.machineLearning().getCalendarEventsAsync(request, RequestOptions.DEFAULT, listener); 

The asynchronous method does not block and returns immediately. Once it is completed the ActionListener is called back using the onResponse method if the execution successfully completed or using the onFailure method if it failed. Failure scenarios and expected exceptions are the same as in the synchronous execution case.

A typical listener for get-calendar-events looks like:

ActionListener<GetCalendarEventsResponse> listener =
    new ActionListener<GetCalendarEventsResponse>() {
        @Override
        public void onResponse(GetCalendarEventsResponse getCalendarsResponse) {
            
        }

        @Override
        public void onFailure(Exception e) {
            
        }
    };

The returned GetCalendarEventsResponse contains the requested events:

long count = response.count(); 
List<ScheduledEvent> scheduledEvents = response.events();
