TranslationServiceClient

TranslationServiceClient

Provides natural language translation operations.

Constructor

new TranslationServiceClient(optionsopt)

Construct an instance of TranslationServiceClient.

Parameters:
Name Type Attributes Description
options object <optional>

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties
Name Type Attributes Description
credentials object <optional>

Credentials object.

Properties
Name Type Attributes Description
client_email string <optional>
private_key string <optional>
email string <optional>

Account email address. Required when using a .pem or .p12 keyFilename.
keyFilename string <optional>

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.
port number <optional>

The port on which to connect to the remote host.
projectId string <optional>

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.
apiEndpoint string <optional>

The domain name of the API remote host.
clientConfig gax.ClientConfig <optional>

Client configuration override. Follows the structure of gapicConfig.
fallback boolean <optional>

Use HTTP fallback mode. In fallback mode, a special browser-compatible transport implementation is used instead of gRPC transport. In browser context (if the window object is defined) the fallback mode is enabled automatically; set options.fallback to false if you need to override this behavior.

Members

apiEndpoint

The DNS address for this API service - same as servicePath(), exists for compatibility reasons.

port

The port for this API service.

scopes

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

The DNS address for this API service.

Methods

batchTranslateDocument(request, optionsopt) → {Promise}

Translates a large volume of documents in asynchronous batch mode. This function provides real-time output as the inputs are being processed. If caller cancels a request, the partial results (for an input file, it's all or nothing) may still be available on the specified output location.

This call returns immediately and you can use google.longrunning.Operation.name to poll the status of the call.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
parent string

Required. Location to make a regional call.

Format: projects/{project-number-or-id}/locations/{location-id}.

The global location is not supported for batch translation.

Only AutoML Translation models or glossaries within the same region (have the same location-id) can be used, otherwise an INVALID_ARGUMENT (400) error is returned.
sourceLanguageCode string

Required. The BCP-47 language code of the input document if known, for example, "en-US" or "sr-Latn". Supported language codes are listed in Language Support (https://cloud.google.com/translate/docs/languages).
targetLanguageCodes Array.<string>

Required. The BCP-47 language code to use for translation of the input document. Specify up to 10 language codes here.
inputConfigs Array.<number>

Required. Input configurations. The total number of files matched should be <= 100. The total content size to translate should be <= 100M Unicode codepoints. The files must use UTF-8 encoding.
outputConfig google.cloud.translation.v3beta1.BatchDocumentOutputConfig

Required. Output configuration. If 2 input configs match to the same file (that is, same input path), we don't generate output for duplicate inputs.
models Array.<number> <optional>

Optional. The models to use for translation. Map's key is target language code. Map's value is the model name. Value can be a built-in general model, or an AutoML Translation model.

The value format depends on model type:

  • AutoML Translation models: projects/{project-number-or-id}/locations/{location-id}/models/{model-id}

  • General (built-in) models: projects/{project-number-or-id}/locations/{location-id}/models/general/nmt, projects/{project-number-or-id}/locations/{location-id}/models/general/base

If the map is empty or a specific model is not requested for a language pair, then default google model (nmt) is used.
glossaries Array.<number> <optional>

Optional. Glossaries to be applied. It's keyed by target language code.
options object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description

const [operation] = await client.batchTranslateDocument(request);
const [response] = await operation.promise();

batchTranslateText(request, optionsopt) → {Promise}

listGlossaries(request, optionsopt) → {Promise}

Lists glossaries in a project. Returns NOT_FOUND, if the project doesn't exist.

Parameters:
Name Type Attributes Description
request Object

The request object that will be sent.

Properties
Name Type Attributes Description
parent string

Required. The name of the project from which to list all of the glossaries.
pageSize number <optional>

Optional. Requested page size. The server may return fewer glossaries than requested. If unspecified, the server picks an appropriate default.
pageToken string <optional>

Optional. A token identifying a page of results the server should return. Typically, this is the value of [ListGlossariesResponse.next_page_token] returned from the previous call to ListGlossaries method. The first page is returned if page_tokenis empty or missing.
filter string <optional>

Optional. Filter specifying constraints of a list operation. Specify the constraint by the format of "key=value", where key must be "src" or "tgt", and the value must be a valid language code. For multiple restrictions, concatenate them by "AND" (uppercase only), such as: "src=en-US AND tgt=zh-CN". Notice that the exact match is used here, which means using 'en-US' and 'en' can lead to different results, which depends on the language code you used when you create the glossary. For the unidirectional glossaries, the "src" and "tgt" add restrictions on the source and target language code separately. For the equivalent term set glossaries, the "src" and/or "tgt" add restrictions on the term set. For example: "src=en-US AND tgt=zh-CN" will only pick the unidirectional glossaries which exactly match the source language code as "en-US" and the target language code "zh-CN", but all equivalent term set glossaries which contain "en-US" and "zh-CN" in their language set will be picked. If missing, no filtering is performed.
options object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description
Promise
  • The promise which resolves to an array. The first element of the array is Array of Glossary. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using listGlossariesAsync() method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.

listGlossariesAsync(request, optionsopt) → {Object}

Equivalent to listGlossaries, but returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

parent string

Required. The name of the project from which to list all of the glossaries.
pageSize number <optional>

Optional. Requested page size. The server may return fewer glossaries than requested. If unspecified, the server picks an appropriate default.
pageToken string <optional>

Optional. A token identifying a page of results the server should return. Typically, this is the value of [ListGlossariesResponse.next_page_token] returned from the previous call to ListGlossaries method. The first page is returned if page_tokenis empty or missing.

If missing, no filtering is performed.
options object <optional>

Call options. See CallOptions for more details.
Returns:
Type Description
Object

An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Glossary. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.
Example
const iterable = client.listGlossariesAsync(request);
for await (const response of iterable) {
  // process response
}

listGlossariesStream(request, optionsopt) → {Stream}
