Interface AmazonLexRuntimeV2Async

All Superinterfaces:

AmazonLexRuntimeV2

All Known Implementing Classes:

AbstractAmazonLexRuntimeV2Async, AmazonLexRuntimeV2AsyncClient

@Generated(value="com.amazonaws:aws-java-sdk-code-generator")
public interface AmazonLexRuntimeV2Async
extends AmazonLexRuntimeV2

Interface for accessing Lex Runtime V2 asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an AsyncHandler can be used to receive notification when an asynchronous operation completes.

Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAmazonLexRuntimeV2Async instead.

Method Detail

deleteSessionAsync

Future<DeleteSessionResult> deleteSessionAsync(DeleteSessionRequest deleteSessionRequest)

Removes session information for a specified bot, alias, and user ID.

You can use this operation to restart a conversation with a bot. When you remove a session, the entire history of the session is removed so that you can start again.

You don't need to delete a session. Sessions have a time limit and will expire. Set the session time limit when you create the bot. The default is 5 minutes, but you can specify anything between 1 minute and 24 hours.

If you specify a bot or alias ID that doesn't exist, you receive a BadRequestException.

If the locale doesn't exist in the bot, or if the locale hasn't been enables for the alias, you receive a BadRequestException.

Parameters:

deleteSessionRequest -

Returns:

A Java Future containing the result of the DeleteSession operation returned by the service.

If the locale doesn't exist in the bot, or if the locale hasn't been enables for the alias, you receive a BadRequestException.

Parameters:

deleteSessionRequest -

asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.

Returns:

A Java Future containing the result of the DeleteSession operation returned by the service.

getSessionAsync

Future<GetSessionResult> getSessionAsync(GetSessionRequest getSessionRequest)

Returns session information for a specified bot, alias, and user.

For example, you can use this operation to retrieve session information for a user that has left a long-running session in use.

If the bot, alias, or session identifier doesn't exist, Amazon Lex V2 returns a BadRequestException. If the locale doesn't exist or is not enabled for the alias, you receive a BadRequestException.

Parameters:

getSessionRequest -

Returns:

A Java Future containing the result of the GetSession operation returned by the service.

AWS API Documentation

getSessionAsync

Future<GetSessionResult> getSessionAsync(GetSessionRequest getSessionRequest,
                                         AsyncHandler<GetSessionRequest,GetSessionResult> asyncHandler)

Returns session information for a specified bot, alias, and user.

For example, you can use this operation to retrieve session information for a user that has left a long-running session in use.

If the bot, alias, or session identifier doesn't exist, Amazon Lex V2 returns a BadRequestException. If the locale doesn't exist or is not enabled for the alias, you receive a BadRequestException.

Parameters:

getSessionRequest -

asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.

recognizeTextAsync

Future<RecognizeTextResult> recognizeTextAsync(RecognizeTextRequest recognizeTextRequest)

Sends user input to Amazon Lex V2. Client applications use this API to send requests to Amazon Lex V2 at runtime. Amazon Lex V2 then interprets the user input using the machine learning model that it build for the bot.

In response, Amazon Lex V2 returns the next message to convey to the user and an optional response card to display.

Parameters:

recognizeTextRequest -

Returns:

A Java Future containing the result of the RecognizeText operation returned by the service.

Future<RecognizeUtteranceResult> recognizeUtteranceAsync(RecognizeUtteranceRequest recognizeUtteranceRequest)

Sends user input to Amazon Lex V2. You can send text or speech. Clients use this API to send text and audio requests to Amazon Lex V2 at runtime. Amazon Lex V2 interprets the user input using the machine learning model built for the bot.

The following request fields must be compressed with gzip and then base64 encoded before you send them to Amazon Lex V2.

• requestAttributes

• sessionState

The following response fields are compressed using gzip and then base64 encoded by Amazon Lex V2. Before you can use these fields, you must decode and decompress them.

• inputTranscript

• interpretations

• messages

• requestAttributes

• sessionState

The example contains a Java application that compresses and encodes a Java object to send to Amazon Lex V2, and a second that decodes and decompresses a response from Amazon Lex V2.

Parameters:

recognizeUtteranceRequest -

Returns:

A Java Future containing the result of the RecognizeUtterance operation returned by the service.
