=== Has Privileges API

[id="{upid}-{api}-request"]
==== Has Privileges Request
The +{request}+ supports checking for any or all of the following privilege types:

* Cluster Privileges
* Index Privileges
* Application Privileges

Privileges types that you do not wish to check my be passed in as +null+, but as least
one privilege must be specified.

[id="{upid}-{api}-response"]
==== Has Privileges Response

The returned +{response}+ contains the following properties

`username`::
The username (userid) of the current user (for whom the "has privileges"
check was executed)

`hasAllRequested`::
`true` if the user has all of the privileges that were specified in the
+{request}+. Otherwise `false`.

`clusterPrivileges`::
A `Map<String,Boolean>` where each key is the name of one of the cluster
privileges specified in the request, and the value is `true` if the user
has that privilege, and `false` otherwise.
+
The method `hasClusterPrivilege` can be used to retrieve this information
in a more fluent manner. This method throws an `IllegalArgumentException`
if the privilege was not included in the response (which will be the case
if the privilege was not part of the request).

`indexPrivileges`::
A `Map<String, Map<String, Boolean>>` where each key is the name of an
index (as specified in the +{request}+) and the value is a `Map` from
privilege name to a `Boolean`. The `Boolean` value is `true` if the user
has that privilege on that index, and `false` otherwise.
+
The method `hasIndexPrivilege` can be used to retrieve this information
in a more fluent manner. This method throws an `IllegalArgumentException`
if the privilege was not included in the response (which will be the case
if the privilege was not part of the request).

`applicationPrivileges`::
A `Map<String, Map<String, Map<String, Boolean>>>>` where each key is the
name of an application (as specified in the +{request}+).
For each application, the value is a `Map` keyed by resource name, with
each value  being another `Map` from privilege name to a `Boolean`.
The `Boolean` value is `true` if the user has that privilege on that 
resource for that application, and `false` otherwise.
+
The method `hasApplicationPrivilege` can be used to retrieve this 
information in a more fluent manner. This method throws an
`IllegalArgumentException` if the privilege was not included in the
response (which will be the case if the privilege was not part of the
request).

<1> `hasMonitor` will be `true` if the user has the `"monitor"`
    cluster privilege.
<2> `hasWrite` will be `true` if the user has the `"write"`
    privilege on the `"logstash-2018-10-05"` index.
<3> `hasRead` will be `true` if the user has the `"read"`
    privilege on all possible indices that would match
    the `"logstash-2018-*"` pattern.
