=== Get Stored Script API
|
|
|
|
[[java-rest-high-get-stored-script-request]]
|
|
==== Get Stored Script Request
|
|
|
|
A `GetStoredScriptRequest` requires an `id`:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/StoredScriptsDocumentationIT.java[get-stored-script-request]
|
|
--------------------------------------------------
|
|
<1> The id of the script
|
|
|
|
==== Optional arguments
|
|
The following arguments can optionally be provided:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/StoredScriptsDocumentationIT.java[get-stored-script-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-get-stored-script-sync]]
|
|
==== Synchronous Execution
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/StoredScriptsDocumentationIT.java[get-stored-script-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-get-stored-script-async]]
|
|
==== Asynchronous Execution
|
|
|
|
The asynchronous execution of a get stored script request requires both the `GetStoredScriptRequest`
|
|
instance and an `ActionListener` instance to be passed to the asynchronous method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/StoredScriptsDocumentationIT.java[get-stored-script-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `GetStoredScriptRequest` to execute and the `ActionListener` to use when
|
|
the execution completes
|
|
|
|
[[java-rest-high-get-stored-script-listener]]
|
|
===== Action 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.
|
|
|
|
A typical listener for `GetStoredScriptResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/StoredScriptsDocumentationIT.java[get-stored-script-execute-listener]
|
|
--------------------------------------------------
|
|
<1> Called when the execution is successfully completed. The response is
|
|
provided as an argument
|
|
<2> Called in case of failure. The raised exception is provided as an argument
|
|
|
|
[[java-rest-high-get-stored-script-response]]
|
|
==== Get Stored Script Response
|
|
|
|
The returned `GetStoredScriptResponse` allows to retrieve information about the
|
|
executed operation as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/StoredScriptsDocumentationIT.java[get-stored-script-response]
|
|
--------------------------------------------------
|
|
<1> The script object consists of a content and a metadata
|
|
<2> The language the script is written in, which defaults to `painless`.
|
|
<3> The content of the script
|
|
<4> Any named options that should be passed into the script. |
