Reference documentation and code samples for the Google Cloud Resource Manager V3 Client class TagValuesClient.
Service Description: Allow users to create and manage tag values.
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:
$tagValuesClient = new TagValuesClient();
try {
$tagValue = new TagValue();
$operationResponse = $tagValuesClient->createTagValue($tagValue);
$operationResponse->pollUntilComplete();
if ($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 = $tagValuesClient->createTagValue($tagValue);
$operationName = $operationResponse->getName();
// ... do other work
$newOperationResponse = $tagValuesClient->resumeOperation($operationName, 'createTagValue');
while (!$newOperationResponse->isDone()) {
// ... do other work
$newOperationResponse->reload();
}
if ($newOperationResponse->operationSucceeded()) {
$result = $newOperationResponse->getResult();
// doSomethingWith($result)
} else {
$error = $newOperationResponse->getError();
// handleError($error)
}
} finally {
$tagValuesClient->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.
Methods
tagValueName
Formats a string containing the fully-qualified path to represent a tag_value resource.
Parameter | |
---|---|
Name | Description |
tagValue |
string
|
Returns | |
---|---|
Type | Description |
string | The formatted tag_value resource. |
parseName
Parses a formatted name string and returns an associative array of the components in the name.
The following name formats are supported: Template: Pattern
- tagValue: tagValues/{tag_value}
The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.
Parameters | |

Name | Description |
formattedName |
string
The formatted name string |
template |
string
Optional name of template to match |
Returns | |
---|---|
Type | Description |
array | An associative array from name component IDs to component values. |
getOperationsClient
Return an OperationsClient object with the same endpoint as $this.
Returns | |
---|---|
Type | Description |
Google\ApiCore\LongRunning\OperationsClient |
resumeOperation
Resume an existing long running operation that was previously started by a long running API method. If $methodName is not provided, or does not match a long running API method, then the operation can still be resumed, but the OperationResponse object will not deserialize the final response.
Parameters | |
---|---|
Name | Description |
operationName |
string

methodName |
string

↳ apiEndpoint |
string
The address of the API remote host. May optionally include the port, formatted as "
|
↳ credentials |
string|array|FetchAuthTokenInterface|CredentialsWrapper
The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored. |
↳ credentialsConfig |
array
Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() . |
↳ disableRetries |
bool
Determines whether or not retries defined by the client configuration should be disabled. Defaults to |
↳ clientConfig |
string|array
Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder. |
↳ transport |
string|TransportInterface
The transport used for executing network requests. May be either the string |
↳ transportConfig |
array
Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options. |
↳ clientCertSource |
callable
A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS. |
createTagValue
Creates a TagValue as a child of the specified TagKey. If a another request with the same parameters is sent while the original request is in process the second request will receive an error. A maximum of 1000 TagValues can exist under a TagKey at any given time.
Parameters | |
