=== Delete Snapshot API

The Delete Snapshot API allows to delete a snapshot.

[[java-rest-high-snapshot-delete-snapshot-request]]
==== Delete Snapshot Request

A `DeleteSnapshotRequest`:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[delete-snapshot-request]
--------------------------------------------------

==== Optional Arguments
The following arguments can optionally be provided:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[delete-snapshot-request-masterTimeout]
--------------------------------------------------
<1> Timeout to connect to the master node as a `TimeValue`
<2> Timeout to connect to the master node as a `String`

[[java-rest-high-snapshot-delete-snapshot-sync]]
==== Synchronous Execution

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[delete-snapshot-execute]
--------------------------------------------------

[[java-rest-high-snapshot-delete-snapshot-async]]
==== Asynchronous Execution

The asynchronous execution of a delete snapshot request requires both the
`DeleteSnapshotRequest` instance and an `ActionListener` instance to be
passed to the asynchronous method:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[delete-snapshot-execute-async]
--------------------------------------------------
<1> The `DeleteSnapshotRequest` 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.

A typical listener for `DeleteSnapshotResponse` looks like:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[delete-snapshot-execute-listener]
--------------------------------------------------
<1> Called when the execution is successfully completed. The response is
provided as an argument
<2> Called in case of a failure. The raised exception is provided as an argument

[[java-rest-high-cluster-delete-snapshot-response]]
==== Delete Snapshot Response

The returned `DeleteSnapshotResponse` allows to retrieve information about the
executed operation as follows:

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[delete-snapshot-response]
--------------------------------------------------
<1> Indicates the node has acknowledged the request
