A simple header-only library to call Java methods in C++ without having to think about all the JNI conversions
The main goal of JONC is to make things simpler. It tries to achive that by using:
- Compile time deduction of method signatures based on its call arguments
- Automatic type conversion from C++ to Java and back
For primitive types, this signature deduction and type convertion is already implemented in the framework, but, of course, you can expand it to any user-defined type.
To use this library, you need to include only the jonc.hpp.
#include <jonc/jonc.hpp>You will also need at least C++11 support (in GCC and Clang, use -std=c++11). If you enable more recent C++ standards, the library will try to make the best use of it, so, if you can, do it!
The test folder has a bunch of examples. Go there and take a look at the README.

- Andrzej Krzemienski for building this amazing Compile-time string concatenation library fully explained in this article. With this library I was able to eliminate all the runtime overhead of dynamically building the method signatures.
