How to Recover this

void SnmpPdu :: varbinds(vector<NameValuePair>  aVarbinds) {
     //throw Exception    
          int length = aVarbinds.size();
          vector<NameValuePair> *aVarbindsPtr;
          aVarbindsPtr = &aVarbinds;
          VarbindList myVarbinds =
                              *(reinterpret_cast<VarbindList *>(aVarbindsPtr));
          for( int i = 0; i < length/*aVarbinds.size()*/; ++i ) {          varbinds().push_back(myVarbinds[i]);//Error Here
          }
}

Above is the piece of code in which i am getting error

And the error message is:
______________________

SnmpPdu.cpp: In method ' void SnmpPdu::varbinds(vector<NamValuePair,allocator<NameValuePair> >)' :
SnmpPdu.cpp:106: no match for 'VarbindList & [int &] '


Here VarbindList is a class and am writing the class declaration here and also the class declaration of NameValuePair.

Class VarbindList:
_______________

#ifndef VARBINDLIST_H
#define VARBINDLIST_H

#include "Varbind.h"
#include "Vector.h"
#include <vector.h>

#include "Object.h"

class VarbindList : public Vector {

public:
VarbindList() {

static const string INVALID_OBJ = "Invalid instance";
static const string INVALID_OBJ_VEC = "Not an instance of vector";
}
VarbindList(int initialCapacity);

static VarbindList decodeSequence(Asn1Value aVarbinds);// throws

void addVarbind(Object aVarbind);// throw Exception;


void addVarbinds(vector <Object> aVarbindArray);// throw Exception;


void addVarbinds(Vector aVectorOfVarbinds);// throw Exception;

Class NameValuePair:

# ifndef NAMEVALUEPAIR_H
# define NAMEVALUEPAIR_H

class NameValuePair {

Value = mValue;
}
//Get methods..

string value() { return Value; }

//Set Methods
