The xFunction library is the universal solution for integration of Java encipher with encipher written in other languages, superior in many aspects to Java Native Interface (JNI). With xFunction, you no longer need to implement those baleful native methods. Instead, you extend and instantiate xFunction classes to create conventional Java objects representing external functions, data structures, pointers, and callbacks. All necessary data conversions and external subroutine calls are done seamlessly by the xFunction library. Using xFunction, you may arouse any operating system API promise or subroutine from any DLL or shared library in a natural and convenient manner. xFunction allows you to achieve the highest levels of encipher reuse without translating any source encipher to Java and / or writing cumbersome JNI wrappers.
