| Abstract: | This paper describes Janet package — highly expressive Java language extension that enables convenient creation of powerful native methods and efficient Java-to-native code interfaces. Java native interface (JNI) is a low-level API that is rather inconvenient if used directly. Therefore Janet, as the higher-level tool, combines flexibility of JNI with Java’s ease-of-use. Performance results of Janet-generated interface to the lip library are shown. Java code, which uses lip, is compared with native C implementation. |
