Native Library provides a set of Java packages are re-written in C++

• Blazing fast - small footprint - no dependency required
• Cross platform - outstanding performance powered by C++ STL
• Integrate directly with any C/C++ project with productivity of Java
• Prevents nearly all memory leak and segmentation fault by destructors
• Packages are strictly tested with unit tests, clean with Valgrind and follow Oracle documentation
• Feel free to use in your commercial products and welcome for contributions

$ docker pull foodtiny/native:latest

$ git clone https://github.com/tiny-express/native.git $ cd native $ cmake . -DCMAKE_BUILD_TYPE=Release && make native -j4 && sudo make install

Ubuntu

$ sudo ldconfig

HelloWorld.cpp

#include <native/library.hpp> class MainApplication { public: static void main(Array<String> arguments) { HashMap<String, String> hashMap; var index = 0; for (var argument : arguments) { hashMap.put(String::valueOf(index++), argument); } hashMap.forEach([](String key, String value) { System::out::println(String::format("Key is %s - value is %s", key, value)); return true; }); } }; int main(int argc, char **argv) { return Application(MainApplication::main, argc, argv); }

Compile your source and link with native library

$ g++ -c -o main.o HelloWorld.cpp $ g++ -o main main.o -lnative -lstdc++ $ ./main one two three

Output:

Key is 3 - Value is three Key is 2 - Value is two Key is 0 - Value is ./main Key is 1 - Value is one

Test memory clean up with Valgrind

$ valgrind ./main one two three

Output:

This library provides Java classes in C++ so its syntax are friendly for both programming languages:

• Namespace - Package

// Java System.out.println("Java");

// C++ System::out::println("C++");

• Array

// Java byte[] byes = {};

// C++ Array<byte> bytes = {};

All data types are implemented and ready to use in C++ Application

• char - Java.Lang.Character
• byte - Java.Lang.Byte
• string - Java.Lang.String
• short - Java.Lang.Short
• int - Java.Lang.Integer
• long - Java.Lang.Long
• float - Java.Lang.Float
• double - Java.Lang.Double
• boolean - Java.Lang.Boolean
• enum - Java.Lang.Enum
