// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
 * Service Description: An interface for managing organization policies.
 *
 * <p>The Cloud Org Policy service provides a simple mechanism for organizations to restrict the
 * allowed configurations across their entire Cloud Resource hierarchy.
 *
 * <p>You can use a `policy` to configure restrictions in Cloud resources. For example, you can
 * enforce a `policy` that restricts which Google Cloud Platform APIs can be activated in a certain
 * part of your resource hierarchy, or prevents serial port access to VM instances in a particular
 * folder.
 *
 * <p>`Policies` are inherited down through the resource hierarchy. A `policy` applied to a parent
 * resource automatically applies to all its child resources unless overridden with a `policy` lower
 * in the hierarchy.
 *
 * <p>A `constraint` defines an aspect of a resource's configuration that can be controlled by an
 * organization's policy administrator. `Policies` are a collection of `constraints` that defines
 * their allowable configuration on a particular resource and its child resources.
 *
 * <p>This class provides the ability to make remote calls to the backing service through method
 * calls that map to API methods. Sample code to get started:
 *
 * <pre>{@code
 * try (OrgPolicyClient orgPolicyClient = OrgPolicyClient.create()) {
 *   PolicyName name = PolicyName.ofProjectPolicyName("[PROJECT]", "[POLICY]");
 *   Policy response = orgPolicyClient.getPolicy(name);
 * }
 * }</pre>
 *
 * <p>Note: close() needs to be called on the OrgPolicyClient object to clean up resources such as
 * threads. In the example above, try-with-resources is used, which automatically calls close().
 *
 * <p>The surface of this class includes several types of Java methods for each of the API's
 * methods:
 *
 * <ol>
 *   <li>A "flattened" method. With this type of method, the fields of the request type have been
 *       converted into function parameters. It may be the case that not all fields are available as
 *       parameters, and not every API method will have a flattened method entry point.
 *   <li>A "request object" method. This type of method only takes one parameter, a request object,
 *       which must be constructed before the call. Not every API method will have a request object
 *       method.
 *   <li>A "callable" method. This type of method takes no parameters and returns an immutable API
 *       callable object, which can be used to initiate calls to the service.
 * </ol>
 *
 * <p>See the individual methods for example code.
 *
 * <p>Many parameters require resource names to be formatted in a particular way. To assist with
 * these names, this class includes a format method for each type of name, and additionally a parse
 * method to extract the individual identifiers contained within names that are returned.
 *
 * <p>This class can be customized by passing in a custom instance of OrgPolicySettings to create().
 * For example:
 *
 * <p>To customize credentials:
 *
 * <pre>{@code
 * OrgPolicySettings orgPolicySettings =
 *     OrgPolicySettings.newBuilder()
 *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
 *         .build();
 * OrgPolicyClient orgPolicyClient = OrgPolicyClient.create(orgPolicySettings);
 * }</pre>
 *
 * <p>To customize the endpoint:
 *
 * <pre>{@code
 * OrgPolicySettings orgPolicySettings =
 *     OrgPolicySettings.newBuilder().setEndpoint(myEndpoint).build();
 * OrgPolicyClient orgPolicyClient = OrgPolicyClient.create(orgPolicySettings);
 * }</pre>
 *
 * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.
