[[java-rest-high-snapshot-get-repository]] === Snapshot Get Repository API The Snapshot Get Repository API allows to retrieve information about a registered repository. [[java-rest-high-snapshot-get-repository-request]] ==== Snapshot Get Repository Request A `GetRepositoriesRequest`: ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-request] -------------------------------------------------- ==== Optional Arguments The following arguments can optionally be provided: ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-request-repositories] -------------------------------------------------- <1> Sets the repositories to retrieve ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-request-local] -------------------------------------------------- <1> The `local` flag (defaults to `false`) controls whether the repositories need to be looked up in the local cluster state or in the cluster state held by the elected master node ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-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-get-repository-sync]] ==== Synchronous Execution ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-execute] -------------------------------------------------- [[java-rest-high-snapshot-get-repository-async]] ==== Asynchronous Execution The asynchronous execution of a snapshot get repository requires both the `GetRepositoriesRequest` instance and an `ActionListener` instance to be passed to the asynchronous method: ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-execute-async] -------------------------------------------------- <1> The `GetRepositoriesRequest` 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 `GetRepositoriesResponse` looks like: ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-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-get-repository-response]] ==== Snapshot Get Repository Response The returned `GetRepositoriesResponse` allows to retrieve information about the executed operation as follows: ["source","java",subs="attributes,callouts,macros"] -------------------------------------------------- include-tagged::{doc-tests}/SnapshotClientDocumentationIT.java[get-repository-response] --------------------------------------------------
