=== Get Calendars API
|
|
Retrieves one or more calendar objects.
|
|
It accepts a `GetCalendarsRequest` and responds
|
|
with a `GetCalendarsResponse` object.
|
|
|
|
[[java-rest-high-x-pack-ml-get-calendars-request]]
|
|
==== Get Calendars Request
|
|
|
|
By default a `GetCalendarsRequest` with no calendar Id set will return all
|
|
calendars. Using the literal `_all` also returns all calendars.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]

<1> Constructing a new request for all calendars
|
|
|
|
|
|
==== Optional Arguments
|
|
The following arguments are optional:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-calendars-id]
|
|
--------------------------------------------------
|
|
<1> Construct a request for the single calendar `holidays`
|
|
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-calendars-page]
|
|
--------------------------------------------------
|
|
<1> The page parameters `from` and `size`. `from` specifies the number of calendars to skip.
|
|
`size` specifies the maximum number of calendars to get. Defaults to `0` and `100` respectively.
|
|
|

[[java-rest-high-x-pack-ml-get-calendars-execution]]
|
|
==== Execution
|
|
The request can be executed through the `MachineLearningClient` contained
|
|
in the `RestHighLevelClient` object, accessed via the `machineLearningClient()` method.
|
|
|
|
["source","java",subs="attributes,callouts,macros"]

--------------------------------------------------
|
|
|
|
[[java-rest-high-x-pack-ml-get-calendars-execution-async]]
|
|
==== Asynchronous Execution
|
|
|
|
The request can also be executed asynchronously:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-calendars-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `GetCalendarsRequest` 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 with the `onResponse` method
|
|
if the execution is successful or the `onFailure` method if the execution
|
|
failed.
|
|
|
|
A typical listener for `GetCalendarsResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-calendars-listener]
|
|
--------------------------------------------------
|
|
<1> `onResponse` is called back when the action is completed successfully
|
|
<2> `onFailure` is called back when some unexpected error occurs
|
|
|
|
[[java-rest-high-x-pack-ml-get-calendars-response]]
|
|
==== Get calendars Response
|
|
|
|
The returned `GetCalendarsResponse` contains the requested calendars:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]

|

<1> The count of calendars that were matched
|
|
<2> The calendars retrieved |
