[[java-rest-high-x-pack-ml-get-datafeed]]
=== Get Datafeed API
The Get Datafeed API provides the ability to get {ml} datafeeds in the cluster.
It accepts a `GetDatafeedRequest` object and responds
with a `GetDatafeedResponse` object.
[[java-rest-high-x-pack-ml-get-datafeed-request]]
==== Get Datafeed Request
A `GetDatafeedRequest` object gets can have any number of `datafeedId` entries.
However, they all must be non-null. An empty list is the same as requesting for all datafeeds.

<1> Constructing a new request referencing existing `datafeedIds`, can contain wildcards
<2> Whether to ignore if a wildcard expression matches no datafeeds.
(This includes `_all` string or when no datafeeds have been specified)
[[java-rest-high-x-pack-ml-get-datafeed-execution]]
==== Execution
The request can be executed through the `MachineLearningClient` contained
in the `RestHighLevelClient` object, accessed via the `machineLearningClient()` method.

include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-datafeed-execute]
--------------------------------------------------
<1> The count of retrieved datafeeds
<2> The retrieved datafeeds
[[java-rest-high-x-pack-ml-get-datafeed-execution-async]]
==== Asynchronous Execution
The request can also be executed asynchronously:

include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-datafeed-execute-async]
--------------------------------------------------
<1> The `GetDatafeedRequest` to execute and the `ActionListener` to use when
the execution completes
The method does not block and returns immediately. The passed `ActionListener` is used
to notify the caller of completion. A typical `ActionListener` for `GetDatafeedResponse` may
look like
["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/MlClientDocumentationIT.java[x-pack-ml-get-datafeed-listener]
--------------------------------------------------
<1> `onResponse` is called back when the action is completed successfully
<2> `onFailure` is called back when some unexpected error occurs
