Create calendars APIedit

Creates a new machine learning calendar. The API accepts a PutCalendarRequest and responds with a PutCalendarResponse object.


A PutCalendarRequest is constructed with a calendar object

Calendar calendar = new Calendar("public_holidays", Collections.singletonList("job_1"), "A calendar for public holidays");
PutCalendarRequest request = new PutCalendarRequest(calendar); 

Create a request with the given calendar.


The returned PutCalendarResponse contains the created calendar:

Calendar newCalendar = response.getCalendar(); 

The created calendar.

Synchronous executionedit

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

PutCalendarResponse response = client.machineLearning().putCalendar(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.

Asynchronous executionedit

Executing a PutCalendarRequest 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 put-calendar method:

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

The PutCalendarRequest to execute and the ActionListener to use when the execution completes

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 put-calendar looks like:

ActionListener<PutCalendarResponse> listener = new ActionListener<PutCalendarResponse>() {
    public void onResponse(PutCalendarResponse response) {

    public void onFailure(Exception e) {

Called when the execution is successfully completed.

Called when the whole PutCalendarRequest fails.
