Manipulating a vector of one class inside of 2 functions of another class

This seems to 开发者_开发问答very very complicated, I tried a lot to solve it, but when I resize a private member inside the template/class, i.e., when I call Operator::InitExtVector, I resize intVect through its address, and when I show/call Operator::ShowExtVector its size is 0 again, which should not be happening. Why the vector information is lost?

I have a template/class, Base.H:

#include <vector>
typedef std::vector <unsigned long int >  varVect1D_ul;

<template <typename PS>
class Base{
private:
   PS bla;
   varVect1D_ul intVect;    

public:
      varVect1D_ul* dataVect(){return &intVect}
}

some operations are done within the Operator class, normal one no template,Operator.H:

 class Operator{
   public:
     .....
   private:

     void InitExtVector(std::vector <Base<float> > BaseVect){ 
             varVect1D_ul *pVect;

             for(i=0...BaseVect.size()){
                 pVect=dataVect();
                 pVect->resize(10);
              }              
        } // end InitExtVector

    void ShowExtVector(std::vector <Base<float> > BaseVect){
             varVect1D_ul *pVect;

             for(i=0...BaseVect.size()){
                 pVect=BaseVect[i].dataVect();
                 cout<<pVect->size();
              } 
    }//end  ShowExtVector  

  };  //end class

, and client code looks like someOperations.C:

  #include "Base.H"
  #include "Operator.H"


  foo(){

   std::vector <Base<float> >  BaseVect(2);
    //do some initization of BseVect;

   Operator *ObjOper= new Operator;    

   ObjOper->InitExtVector(BaseVect);
   ObjOper-> ShowExtVector(BaseVect);



  }

All syntax is Ok , the addresses of pVect inside InitExtVect and ShowExtVector are the same

Any help will be gladly appreciated

I think you want to take your vectors in by reference:

void InitExtVector(std::vector <Base<float> > & BaseVect);
void ShowExtVector(std::vector <Base<float> > & BaseVect);

Also, did you mean this in InitExtVector:

for(i=0 ; i < BaseVect.size() ; ++i){
    pVect=BaseVect[i].dataVect();
    pVect->resize(10);
}
