Google Cloud Ai Platform V1 Client - Class IndexEndpointServiceClient (0.10.0)

Reference documentation and code samples for the Google Cloud Ai Platform V1 Client class IndexEndpointServiceClient.

Service Description: A service for managing Vertex AI's IndexEndpoints.

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:

$indexEndpointServiceClient = new IndexEndpointServiceClient();
try {
    $formattedParent = $indexEndpointServiceClient->locationName('[PROJECT]', '[LOCATION]');
    $indexEndpoint = new IndexEndpoint();
    $operationResponse = $indexEndpointServiceClient->createIndexEndpoint($formattedParent, $indexEndpoint);
    $operationResponse->pollUntilComplete();
    if ($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 = $indexEndpointServiceClient->createIndexEndpoint($formattedParent, $indexEndpoint);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $indexEndpointServiceClient->resumeOperation($operationName, 'createIndexEndpoint');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        $result = $newOperationResponse->getResult();
    // doSomethingWith($result)
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $indexEndpointServiceClient->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

indexName

Formats a string containing the fully-qualified path to represent a index resource.

Parameters
NameDescription
project string
location string
index string
Returns
TypeDescription
stringThe formatted index resource.

indexEndpointName

Formats a string containing the fully-qualified path to represent a index_endpoint resource.

Parameters
NameDescription
project string
location string
indexEndpoint string
Returns
TypeDescription
stringThe formatted index_endpoint resource.

locationName

Formats a string containing the fully-qualified path to represent a location resource.

Parameters
NameDescription
project string
location string
Returns
TypeDescription
stringThe formatted location 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

  • index: projects/{project}/locations/{location}/indexes/{index}
  • indexEndpoint: projects/{project}/locations/{location}/indexEndpoints/{index_endpoint}
  • location: projects/{project}/locations/{location}

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

formattedName string

The formatted name string

template string

Optional name of template to match

Returns
TypeDescription
arrayAn associative array from name component IDs to component values.

getOperationsClient

Return an OperationsClient object with the same endpoint as $this.

Returns
TypeDescription
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
NameDescription
operationName string

The name of the long running operation

methodName string

The name of the method used to start the operation

Returns
TypeDescription
Google\ApiCore\OperationResponse

__construct

Constructor.

Parameters
NameDescription
options array

Optional. Options for configuring the service API wrapper.

↳ 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 {@see} object or {@see} 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 {@see} .

↳ disableRetries bool

Determines whether or not retries defined by the client configuration should be disabled. Defaults to false.

↳ 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 rest or grpc. Defaults to grpc if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated {@see} object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.

↳ 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 {@see} and {@see} methods for the supported options.
