Method details

isSupported

public static boolean isSupported()

Returns

whether automatic Smart Reply is available

isSupported

public static boolean isSupported(LanguageOptions options)

Tests whether Smart Reply is available for a backend selection.

This capability check creates and closes a temporary native backend. Retain a Session from open(LanguageOptions) when the application will immediately request repeated suggestions.

Parameters

options LanguageOptions: backend selection, or null for defaults

Returns

whether the selected backend supports Smart Reply

open

public static SmartReply.Session open(LanguageOptions options)

Opens a reusable Smart Reply session. Reuse it for conversations that need repeated suggestions to avoid recreating the native client.

Parameters

options LanguageOptions: backend options, or null

Returns

a reusable session that owns one native language backend

Throws

UnsupportedOperationException: if the selected backend is absent

suggest

public static AsyncResource<String[]> suggest(SmartReplyMessage[] conversation, LanguageOptions options)

The conversation array and option values are copied before backend work begins. SmartReplyMessage values are immutable. Cancelling the returned resource suppresses late result callbacks; the temporary backend is released after its pending native work settles.

Parameters

conversation SmartReplyMessage[]: chronological messages, oldest first
options LanguageOptions: backend options, or null

Returns

asynchronous suggestions, possibly an empty array
