Method Details

isSupported

public static boolean isSupported()

Returns:

whether automatic language identification is available

isSupported

public static boolean isSupported(LanguageOptions options)

Parameters:

options - backend selection, or null for defaults

Returns:

whether the selected backend is available on this target

open

public static LanguageIdentifier.Session open(LanguageOptions options)

Opens a reusable language-identification session. Reusing a session avoids repeatedly creating the native recognizer when classifying many strings. Close it when no more identifications are pending.

Parameters:

options - backend and confidence options, or null

Returns:

a reusable session that owns one native language backend

Throws:

UnsupportedOperationException - if the selected backend is absent

identify

public static AsyncResource<LanguageCandidate[]> identify(String text,
 LanguageOptions options)

Identifies possible languages off the EDT without uploading text. The option values are copied before the backend starts, so later mutations of the supplied object cannot alter the pending identification. Cancelling the returned resource suppresses late result callbacks; the temporary backend is released after its pending native work settles.

Parameters:

text - non-null text to classify

options - backend and confidence options, or null

Returns:

asynchronous ranked candidates; may be empty for undetermined text
