For c# calls java, here presents a new method, which ues cle developed by srplab.A function “Add” is defined in lua which returns the sum of two input integers, the function also calls c# method “Show” to print the result.

There are three steps:

1.       Init cle, create service group, and create service.

2.       Define extends class of StarObjectClass, and defines a new function “Add” of it.

3.       Create interface object, named “TestClass”.

import com.srplab.www.starcore.*;

//--Step2 : Define extends class of StarObjectClass, and defines a new function “Add” of it.

class MyObjectClass extends StarObjectClass

{

    public int Add(StarObjectClass self, int x, int y)

{

//--Callback to script function

        self._Call("Show", x + y);

        return x + y;

    }

    public MyObjectClass(StarObjectClass srcobj)

    {

              super(srcobj);

    }

}

public class AddFunctionService{

         public static void main(String[] args){

         //--Step1 : Init cle, create service group,import sharelibrary,  and create service

                   StarCoreFactory starcore= StarCoreFactory.GetFactory();

                   StarServiceClass Service=starcore._InitSimple("AddFunctionService","123",0,0);

         //--Step3 : Create interface object, named “TestClass”.

                   MyObjectClass Obj = new MyObjectClass(Service._New("TestClass"));

    }

} 

For c# code calls the above java code, there are four steps;

1.       Init cle, create service group, import java file, and create service.

2.       Define extends class of StarObjectClass, which implement callback function “Show”.

3.       Create Instance of object “TestClass” defined in java file.

4.       Call function “Add”.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using star_csharp;

namespace csharp_call

{

class MyObjectClass : StarObjectClass{

//--Step2 : Define extends class of StarObjectClass and implements callback function “Show”.

       public void Show( StarObjectClass self,int para )

       {

         Console.WriteLine("print from java call back "+para);

         return;

       }

         public MyObjectClass(StarObjectClass srcobj):base(srcobj){

    }     

    }

    class Program

    {

        static void Main (string[] args)

        {

//--Step1 : Init cle, create service group,import java file,  and create service

         StarCoreFactory starcore= StarCoreFactory.GetFactory();

         StarServiceClass Service=starcore._InitSimple("test","123",0,0," AddFunctionService.lua?script=lua");

         //--Step3 : Create Instance of object “TestClass” defined in java.

         MyObjectClass a = new MyObjectClass( Service._GetObject("TestClass")._New() );

         //--Step4 : call function “Add”.

        Console.WriteLine("Add returns : " + a._Call("Add", 12, 34));

        starcore._ModuleExit();

        }

    }

}
