Create java native method for constructor

I am writing a program in Java and I would like to create a native interface for a library written in C++. But I am confused with how to write a native method declaration for a constructor.

Say I have this C++ class and constructor:

 template <class _Tp,class _Val>
  class Arbitrator
  {
  public:
    Arbitrator();
  }

How would I write a native method declaration?

This is what I'm doing so far: package hbot.proxy.bwsal.arbitrator;

public class Arbitrator<Tp, Val>
{
    public native Arbitrator Arbitrator();
}

Is this how I would do this?

Thanks

Solution

  • Create native method. For example, private native void init(). Call it from constructor in Java. In it's JNI implementation access C++ class as needed.

    You will have to use JNI generated method signatures anyway, so you can't map directly Java class to C++ class if that's what you wanted to do.
