POWhat do getters and setters look like for a struct (that lives оn the heap)?

copied!<p>Very simple question - how can I access data for a struct that lives inside the heap?</p> <p>Additional information:: I have a class called "A" and a struct within this class called "B". Every "B" that is created will live on the heap. Class "A" is intended to have a vector of "B"'s as a private data member (ie. the class "A" can hold many "B"'s). I have a method in class "A" that will add another new instance of "B" in the vector that "A" has. I also have another method in class "A" that will update every single element that is in the vector of "B" instances. My questions are:</p> <p>How do I use the getters and setters within my struct?</p> <p>Here is some code that might help (note: grafix.h is a graphical library)</p> <pre><code>//.h file #pragma once #include <vector> #include "grafix.h" class A { public: ~A(); A(); void addB(); void updateB(); private: struct B { public: ~B() { delete p_b; p_b = 0; } B() { p_b = new B; //I need this here p_ball->x = 0; p_ball->y = 0; p_ball->r = 15; } void setxy(int X, int Y) { //What does this look like? //This? x = X; //? y = Y; } int retx() { //Likewise.... ? return x; //? } int rety() { return y; } void update() { draw(); //Movement code taken out for time being } private: int x,y; //xy int r; //radius B* p_b; //pointer to object, do I need this? void draw() { draw_circle_filled(x,y,r); //how can I access the data within the struct B here? //do I use the getters/setters? dereference?? } }; vector <Ball*> bs; //Holds all of the B's that have been created }; </code></pre> <p>And then the .cpp file that has the methods. This is where I have my question, am I typing in the right syntax??</p> <pre><code>#include "A.h" A::A() { addB(); } void A::addB() { B* b; bs.push_back(b); } void A::updateB() { for(int i = 0; i < bs.size(); i++) { bs[i]->update(); } } </code></pre>
