NativeLibLoader

public class NativeLibLoader

Class to load the native lib libtreelite4j.dylib. Normally, users do not have to worry about this class, since mvn package automatically bundles libtreelite4j.dylib into the JAR file. However, the method createTempFileFromResource may be useful to some users, who would like to bundle other files into the JAR file as well.

public static String createTempFileFromResource(String path)

The created temp file.
