==== Get Alias Request

The Get Alias API uses +{request}+ as its request object.
One or more aliases can be optionally provided either at construction
time or later on through the relevant setter method.

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request]
--------------------------------------------------

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

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-alias]

["source","java",subs="attributes,callouts,macros"]
--------------------------------------------------
include-tagged::{doc-tests-file}[{api}-request-indices]
--------------------------------------------------
<1> The index or indices that the alias is associated with

["source","java",subs="attributes,callouts,macros"]

how wildcard expressions are expanded when looking for aliases that belong to
specified indices.

the elected master node
