Dynamic Library: Do you need to export variables of a class?

[babaliaris]

Lets say you have the following class.

#pragma once
#include <iostream>
#include <vector>

//-_-_-_-_-_-Class Declerations-_-_-_-_-_-//
class Renderer;
class Brain;
class Transform;
//-_-_-_-_-_-Class Declerations-_-_-_-_-_-//

class Sprite
{
//Public Members.
public:

	Transform *transform;

	std::string tag;


//Private Members.
private:

	std::vector<Brain *> m_brains;


//Public Methods.
public:

	//Constructor.
	__decspec(dllexport) Sprite(std::string imagePath, glm::vec2 position = glm::vec2(0.0f, 0.0f), std::string tag = "");

	//Deconstructor.
	__decspec(dllexport) ~Sprite();




//Private Methods.
private:

	//Render Method.
	__decspec(dllexport) void Render(Renderer *rednerer);

	};

Do i also need to export the transform and tag variables? Or __declspec only reference to methods and functions?
The reason I'm not putting __declspec before the class name but I manually place it in each method is because i get a link warning
for the std::string tag .I searched on google and they say that you should not export std::base_string templates because they are
already exported. So i tried to fix that by manually choosing which method i want to export.

Also does it make sense to export private Methods?
