Google Cloud Translation v2 API - Class AdvancedTranslationClient (3.2.0)

public abstract class AdvancedTranslationClient : IDisposable

Reference documentation and code samples for the Google Cloud Translation v2 API class AdvancedTranslationClient.

Abstract class providing operations for Google Cloud Translation. This class uses strings for model names, unlike TranslationClient which uses the TranslationModel enum. This makes it less convenient to use for simple cases, but more powerful in allowing arbitrary custom models to be specified.

Inheritance

object > AdvancedTranslationClient

Implements

IDisposable

Inherited Members

object.GetHashCode()

object.GetType()

object.MemberwiseClone()

object.ToString()

Derived Types

AdvancedTranslationClientImpl

Namespace

GoogleGoogle.CloudGoogle.Cloud.TranslationV2

Assembly

Google.Cloud.Translation.V2.dll

Remarks

This abstract class is provided to enable testability while permitting additional operations to be added in the future. See Create(GoogleCredential, string), CreateAsync(GoogleCredential, string) and CreateFromApiKey(string, string) to construct instances; alternatively, you can construct a AdvancedTranslationClientImpl directly from a TranslateService.

All instance methods declared in this class are virtual, with an implementation which simply throws NotImplementedException. All these methods are overridden in AdvancedTranslationClientImpl.

This class implements IDisposable; however, the Dispose() method only requires calling if many short-lived instances of AdvancedTranslationClient are being created. Most code would be expected to create a single AdvancedTranslationClient instance, and use this instance throughout the lifetime of the application. In this case, Dispose need not be called.

Properties

DefaultModel

public virtual string DefaultModel { get; }

The default translation model used by this client.

Property Value
Type	Description
`string`

Remarks

Each Translate method has an optional parameter to override this.

Service

public virtual TranslateService Service { get; }

The underlying translation service object used by this client.

Property Value
Type	Description
`TranslateService`

Remarks

The AdvancedTranslationClient class only provides convenience operations built on top of an existing service object. Any more complex operations which are not supported by this wrapper may wish to use the same service object as the wrapper, in order to take advantage of its configuration (for authentication, application naming etc).

Methods

Create()

public static AdvancedTranslationClient Create()

Synchronously creates a nAdvancedTranslationClient using application default credentials. For any non-default values, please use AdvancedTranslationClientBuilder.

Returns
Type	Description
`AdvancedTranslationClient`

Create(GoogleCredential, string)

public static AdvancedTranslationClient Create(GoogleCredential credential = null, string model = null)

Synchronously creates a AdvancedTranslationClient, using application default credentials if no credentials are specified.

Parameters
Name	Description
`credential`	`GoogleCredential` Optional GoogleCredential. If this is non-null, default scopes are applied to it (for credential types that support scoping), overriding any existing scopes in the credentials. To use scoped credentials without any modifications, create a AdvancedTranslationClientBuilder and set the Credential property.
`model`	`string` The default translation model to use. Defaults to null, indicating that by default no model is specified in requests.

Returns
Type	Description
`AdvancedTranslationClient`	The created AdvancedTranslationClient.

Remarks

If a credential is supplied, the default scopes are applied to it (for credential types that support scoping), overriding any existing scopes in the credentials. To use scoped credentials without any modifications, create a AdvancedTranslationClientBuilder and set the Credential property.

CreateAsync()

public static Task<AdvancedTranslationClient> CreateAsync()

Asynchronously creates an AdvancedTranslationClient using application default credentials. For any non-default values, please use AdvancedTranslationClientBuilder.

Returns
Type	Description
`TaskAdvancedTranslationClient`	The task representing the created AdvancedTranslationClient.

CreateAsync(GoogleCredential, string)

public static Task<AdvancedTranslationClient> CreateAsync(GoogleCredential credential = null, string model = null)

Asynchronously creates a AdvancedTranslationClient, using application default credentials if no credentials are specified.

Parameters
Name	Description
`credential`	`GoogleCredential` Optional GoogleCredential. If this is non-null, default scopes are applied to it (for credential types that support scoping), overriding any existing scopes in the credentials. To use scoped credentials without any modifications, create a AdvancedTranslationClientBuilder and set the Credential property.
`model`	`string` The default translation model to use. Defaults to null, indicating that by default no model is specified in requests.

Returns
Type	Description
`TaskAdvancedTranslationClient`	The task representing the created AdvancedTranslationClient.

Remarks

CreateFromApiKey(string, string)

public static AdvancedTranslationClient CreateFromApiKey(string apiKey, string model = null)

Creates a AdvancedTranslationClient from an API key instead of using OAuth2 credentials.

Parameters
Name	Description
`apiKey`	`string` API key to use. Must not be null.
`model`	`string` The default translation model to use. Defaults to null, indicating that by default no model is specified in requests.

Returns
Type	Description
`AdvancedTranslationClient`	The created AdvancedTranslationClient.

Remarks

You are encouraged to use OAuth2 credentials where possible. This method is primarily provided to make the transition from using API keys to OAuth2 credentials straightforward.
