Problem with push_back.

[AnuSree]

Hi

I am getting error with push_back, some one please help me ASAP in this
aspect here am sending the needful info.

_______________

Class VarbindList:

_______________

#ifndef VARBINDLIST_H

#define VARBINDLIST_H

#include "Varbind.h"

#include "Vector.h"

#include <vector.h>

#include "Snmp.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;

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

vector <Varbind> getVarbindArray();

vector <Object> encode();

char * toString();

// Constants

private:

static const string INVALID_OBJ;// = "Invalid instance";

static const string INVALID_OBJ_VEC;// = "Not an instance of vector";

};

#endif // VARBINDLIST_H

___________________

Class NameValuePair:

___________________

# ifndef NAMEVALUEPAIR_H

# define NAMEVALUEPAIR_H

#include "Snmp.h"

# include "AllIncludes.h"

class NameValuePair {

private:

string Name;

string Value;

public:

NameValuePair() { }

NameValuePair(string mName, string mValue) {

Name = mName;

Value = mValue;

}

//Get methods..

string name() { return Name; }

string value() { return Value; }

//Set Methods

void name(string mName) { Name = mName; }

void value(string mValue) { Value = mValue; }

};

# endif

And this is the peice of code of a method in which i am getting error
when am using push_back.

Message SnmpSouthAdaptor :: encode(Request req) {

vector<NameValuePair> ar = req.arr();

VarbindList varbinds;// = VarbindList();

for ( int i = 0; i < ar.size(); ++i ) {

varbinds.push_back(ar); //Error Here

}

}

Here in varbinds.push_back(ar), i have to type cast the type of ar
from vector<NameValuePair> to the type VarbindList but am not getting
how to do this,since the type of the ar is not the same as the type
of varbind am getting error :

no matching function for call to `VarbindList::push_back
(NameValuePair &)'

Here VarbindList is a class and varbinds is the object of the class
VarbindList and ar is of type vector<NameValuePair>.

I wrote the class declarations of both VarbindList and NameValuePair on
the top.Please help me ASAP
