=== Get Mappings API

[[java-rest-high-get-mappings-request]]
|
|
==== Get Mappings Request
|
|
|
|
A `GetMappingsRequest` can have an optional list of indices and optional list of types:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-request]
|
|
--------------------------------------------------
|
|
<1> An empty request that will return all indices and types
|
|
<2> Setting the indices to fetch mapping for
|
|
<3> The types to be returned
|
|
|
|
==== Optional arguments
|
|
The following arguments can also optionally be provided:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-request-masterTimeout]
|
|
--------------------------------------------------
|
|
<1> Timeout to connect to the master node as a `TimeValue`
|
|
<2> Timeout to connect to the master node as a `String`
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-request-indicesOptions]
|
|
--------------------------------------------------
|
|
<1> Options for expanding indices names
|
|
|
|
[[java-rest-high-get-mappings-sync]]
|
|
==== Synchronous Execution
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-execute]
|
|
--------------------------------------------------
|
|
|
|
[[java-rest-high-get-mapping-async]]
|
|
==== Asynchronous Execution
|
|
|
|
The asynchronous execution of a get mappings request requires both the
|
|
`GetMappingsRequest` instance and an `ActionListener` instance to be passed to
|
|
the asynchronous method:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-execute-async]
|
|
--------------------------------------------------
|
|
<1> The `GetMappingsRequest` 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 `GetMappingsResponse` looks like:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-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-mapping-response]]
|
|
==== Get Mappings Response
|
|
|
|
The returned `GetMappingsResponse` allows to retrieve information about the
|
|
executed operation as follows:
|
|
|
|
["source","java",subs="attributes,callouts,macros"]
|
|
--------------------------------------------------
|
|
include-tagged::{doc-tests}/IndicesClientDocumentationIT.java[get-mapping-response]
|
|
--------------------------------------------------
|
|
<1> Returning all indices' mappings
|
|
<2> Retrieving the mappings for a particular index and type
|
|
<3> Getting the mappings for the "tweet" as a Java Map
