public class DetectorFactory
extends java.lang.Object

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