public class DetectorFactory
extends Object

Language Detector Factory Class This class manages an initialization and constructions of Detector. Before using language detection library, load profiles with loadProfile(String) method and set initialization parameters. When the language detection, construct Detector instance via create(). See also Detector's sample code.

• 4x faster improvement based on Elmer Garduno's code. Thanks!

Method Detail

loadProfile

public static void loadProfile(String profileDirectory)
                        throws LangDetectException

Load profiles from specified directory. This method must be called once before language detection.

Parameters:

profileDirectory - profile directory path

Throws:

LangDetectException - Can't open profiles(error code = ErrorCode.FileLoadError) or profile's format is wrong (error code = ErrorCode.FormatError)

loadProfile

public static void loadProfile(File profileDirectory)
                        throws LangDetectException

Load profiles from specified directory. This method must be called once before language detection.

Parameters:

profileDirectory - profile directory path

Throws:

LangDetectException - Can't open profiles(error code = ErrorCode.FileLoadError) or profile's format is wrong (error code = ErrorCode.FormatError)

loadProfile

public static void loadProfile(List<String> json_profiles)
                        throws LangDetectException

Load profiles from specified directory. This method must be called once before language detection.

Throws:

LangDetectException - Can't open profiles(error code = ErrorCode.FileLoadError) or profile's format is wrong (error code = ErrorCode.FormatError)

clear

public static void clear()

Clear loaded language profiles (reinitialization to be available)

create

public static Detector create()
                       throws LangDetectException

Construct Detector instance

Returns:

Detector instance

Throws:

LangDetectException

create

public static Detector create(double alpha)
                       throws LangDetectException

Construct Detector instance with smoothing parameter

Parameters:

alpha - smoothing parameter (default value = 0.5)

Returns:

Detector instance

Throws:

LangDetectException

setSeed
