/**
 * Service Description: VMwareEngine manages VMware's private clusters in the Cloud.
 *
 * 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:
 *
 * ```
 * $vmwareEngineClient = new VmwareEngineClient();
 * try {
 *     $formattedParent = $vmwareEngineClient->privateCloudName('[PROJECT]', '[LOCATION]', '[PRIVATE_CLOUD]');
 *     $clusterId = 'cluster_id';
 *     $cluster = new Cluster();
 *     $operationResponse = $vmwareEngineClient->createCluster($formattedParent, $clusterId, $cluster);
 *     $operationResponse->pollUntilComplete();
 *     if ($operationResponse->operationSucceeded()) {
 *         $result = $operationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $operationResponse->getError();
 *         // handleError($error)
 *     }
 *     // Alternatively:
 *     // start the operation, keep the operation name, and resume later
 *     $operationResponse = $vmwareEngineClient->createCluster($formattedParent, $clusterId, $cluster);
 *     $operationName = $operationResponse->getName();
 *     // ... do other work
 *     $newOperationResponse = $vmwareEngineClient->resumeOperation($operationName, 'createCluster');
 *     while (!$newOperationResponse->isDone()) {
 *         // ... do other work
 *         $newOperationResponse->reload();
 *     }
 *     if ($newOperationResponse->operationSucceeded()) {
 *         $result = $newOperationResponse->getResult();
 *     // doSomethingWith($result)
 *     } else {
 *         $error = $newOperationResponse->getError();
 *         // handleError($error)
 *     }
 * } finally {
 *     $vmwareEngineClient->close();
 * }
 * ```
 *
 * 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 parseName method to extract the individual identifiers
 * contained within formatted names that are returned by the API.

     *           A callable which returns the client cert as a string. This can be used to

     * and all private cloud resources are irreversibly removed and billing stops.
     * During the final removal process, `PrivateCloud.state` is set to `PURGING`.

     *           The maximum number of resources contained in the underlying API

     *           there are additional values to be retrieved.
     *     @type string $pageToken
     *           A page token is used to specify a page of values to be returned.
     *           If no page token is specified (the default), the first page
     *           of values will be returned. Any page token used here must have
     *           been generated by a previous call to the API.
     *     @type string $filter
     *           A filter expression that matches resources returned in the response.
     *           The expression must specify the field name, a comparison
     *           operator, and the value that you want to use for filtering. The value
     *           must be a string, a number, or a boolean. The comparison operator
     *           must be `=`, `!=`, `>`, or `<`.
     *
     *           For example, if you are filtering a list of network policies, you can
     *           exclude the ones named `example-policy` by specifying
     *           `name != "example-policy"`.
     *
     *           To filter on multiple expressions, provide each separate expression within
     *           parentheses. For example:
     *           ```
     *           (name = "example-policy")
     *           (createTime > "2021-04-12T08:15:10.40Z")
     *           ```
     *
     *           By default, each expression is an `AND` expression. However, you
     *           can include `AND` and `OR` expressions explicitly.
     *           For example:
     *           ```
     *           (name = "example-policy-1") AND
     *           (createTime > "2021-04-12T08:15:10.40Z") OR
     *           (name = "example-policy-2")
     *           ```
     *     @type string $orderBy
     *           Sorts list results by a certain order. By default, returned results
     *           are ordered by `name` in ascending order.
     *           You can also sort results in descending order based on the `name` value
     *           using `orderBy="name desc"`.
     *           Currently, only ordering by `name` is supported.

     * @param string $parent       Required. The resource name of the location to query for
     *                             VMware Engine networks. Resource names are schemeless URIs that follow the
     *                             conventions in https://cloud.google.com/apis/design/resource_names. For
     *                             example: `projects/my-project/locations/global`
     * @param array  $optionalArgs {
     *     Optional.
     *
     *     @type int $pageSize
     *           The maximum number of resources contained in the underlying API
     *           response. The API may return fewer values in a page, even if
     *           there are additional values to be retrieved.
     *     @type string $pageToken
     *           A page token is used to specify a page of values to be returned.
     *           If no page token is specified (the default), the first page
     *           of values will be returned. Any page token used here must have
     *           been generated by a previous call to the API.
     *     @type string $filter
     *           A filter expression that matches resources returned in the response.
     *           The expression must specify the field name, a comparison
     *           operator, and the value that you want to use for filtering. The value
     *           must be a string, a number, or a boolean. The comparison operator
     *           must be `=`, `!=`, `>`, or `<`.
     *
     *           For example, if you are filtering a list of network peerings, you can
     *           exclude the ones named `example-network` by specifying
     *           `name != "example-network"`.
     *
     *           To filter on multiple expressions, provide each separate expression within
     *           parentheses. For example:
     *           ```
     *           (name = "example-network")
     *           (createTime > "2021-04-12T08:15:10.40Z")
     *           ```
     *
     *           By default, each expression is an `AND` expression. However, you
     *           can include `AND` and `OR` expressions explicitly.
     *           For example:
     *           ```
     *           (name = "example-network-1") AND
     *           (createTime > "2021-04-12T08:15:10.40Z") OR
     *           (name = "example-network-2")
     *           ```
     *     @type string $orderBy
     *           Sorts list results by a certain order. By default, returned results
     *           are ordered by `name` in ascending order.
     *           You can also sort results in descending order based on the `name` value
     *           using `orderBy="name desc"`.
     *           Currently, only ordering by `name` is supported.
     *     @type RetrySettings|array $retrySettings
     *           Retry settings to use for this call. Can be a {@see RetrySettings} object, or an

     *           the request if it has already been completed. The server guarantees that a
     *           request doesn't result in creation of duplicate commitments for at least 60
     *           minutes.
     *
     *           For example, consider a situation where you make an initial request and the
     *           request times out. If you make the request again with the same request
     *           ID, the server can check if original operation with the same request ID
     *           was received, and if so, will ignore the second request. This prevents
     *           clients from accidentally creating duplicate commitments.
     *
     *           The request ID must be a valid UUID with the exception that zero UUID is
