Google Cloud Dialogflow V2 Client - Class EntityTypesClient (1.0.1)

Reference documentation and code samples for the Google Cloud Dialogflow V2 Client class EntityTypesClient.

Service Description: Service for managing EntityTypes.

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:

$entityTypesClient = new EntityTypesClient();
try {
    $formattedParent = $entityTypesClient->entityTypeName('[PROJECT]', '[ENTITY_TYPE]');
    $entities = [];
    $operationResponse = $entityTypesClient->batchCreateEntities($formattedParent, $entities);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        // operation succeeded and returns no value
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $entityTypesClient->batchCreateEntities($formattedParent, $entities);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $entityTypesClient->resumeOperation($operationName, 'batchCreateEntities');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        // operation succeeded and returns no value
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $entityTypesClient->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.

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

agent: projects/{project}/agent
entityType: projects/{project}/agent/entityTypes/{entity_type}
projectAgent: projects/{project}/agent
projectEntityType: projects/{project}/agent/entityTypes/{entity_type}

__construct

Constructor.

Parameters
Name	Description
`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`.
