send a whole vector as a parameter from java to c++

[manel1989]

hi all!

i have to send a whole vector as a parameter from a code java (eclipse) to a c++ code(VS2010)i have some quations about that:

1. how can i send the whole vector in once? i already know how to send it element by element so i want to try this because i want to minimize the time of sending a vector and the time of receipt of the response since I sent this vector from java and I want the result of c + + code in Java also. this is my code in java which send element by element.

          for(int i=0; i<R1.size();i++)
   
            {   
              pw.println(R1.get(i));
              }
   

   here my c++ code for reception:

   vector<int> ReadInput::lire_RAM_nodes()
   {

   for ( int i=0;i < NbrNodes; i++)
   

   {
   std::cin >> a;
   R.push_back(a);
   }
   /for ( int i=0; i<R.size();i++)
   {
   std::cout<<R[i]<< std::endl;
   }/
   return R;
   }

2. In my c++ code i have to use 2 variables n and m more then once ,so for some raison that i dont know, when i need to use m or n i have to send theme again from java code!!!!! and that's feel no right i think!!!!!
   here is my java code :for sending m and n :

              pw.println(m);
              pw.println(n);
              pw.println(m);
              pw.println(n);
   

and here is my c++ code that recives m and n from java :

 const int ReadInput::lire_size_nodes()
{
    cin>>NbrNodes;
    //cout<<NbrNodes<<endl;
    return NbrNodes;
}
 const int ReadInput::lire_size_testers()
{
    cin>>NbrTersters;
    //cout<<NbrTersters<<endl;
    return NbrTersters;
}

and here when i use m and n in c++ :

MMKP (const Options& opt) : a(*this,readinput.lire_size_nodes()*readinput.lire_size_testers(),0,1){

Matrix <BoolVarArray> X (a,readinput.lire_size_nodes(),readinput.lire_size_testers());

so do you have any idea for that?? do i have to change any thing about that ??

thank you for any help
