+<div class="method">
+    <code class="details" id="lintPolicy">lintPolicy(body, x__xgafv=None)</code>
+  <pre>Lints a Cloud IAM policy object or its sub fields. Currently supports
+google.iam.v1.Policy, google.iam.v1.Binding and
+google.iam.v1.Binding.condition.
+
+Each lint operation consists of multiple lint validation units.
+Validation units have the following properties:
+
+- Each unit inspects the input object in regard to a particular
+  linting aspect and issues a google.iam.admin.v1.LintResult
+  disclosing the result.
+- Domain of discourse of each unit can be either
+  google.iam.v1.Policy, google.iam.v1.Binding, or
+  google.iam.v1.Binding.condition depending on the purpose of the
+  validation.
+- A unit may require additional data (like the list of all possible
+  enumerable values of a particular attribute used in the policy instance)
+  which shall be provided by the caller. Refer to the comments of
+  google.iam.admin.v1.LintPolicyRequest.context for more details.
+
+The set of applicable validation units is determined by the Cloud IAM
+server and is not configurable.
+
+Regardless of any lint issues or their severities, successful calls to
+`lintPolicy` return an HTTP 200 OK status code.
+
+Args:
+  body: object, The request body. (required)
