Thread: Call to new to create objects that go into a vector

I don't have the code in front of me & I'm using a SDK. I will try to reproduce the code from memory. I need to know the best way release memory back from when I create new objects from calling new.

I have a public member variable (vector of pointers), that is passed by address to a different class member function. There its filled with the address of a new object.

Code:

 
for (unsigned int h = 2; h < ArenaSize; h+=3){
if(ArenaBuffer[h] > THRESHOLD){
Rx = h%WIDTH;
Ry = h/HEIGHT;
RedXY *XYobject = new(nothrow) RedXY;
XYobject->iX = Rx;
XYobject->iY = Ry;
(*vPixels).pushback(XYobject);
}
}

After it is filled in that class member function, it is used in another member function WITHIN its class.

Code:

pBitmap->drawline(RGB(255,255,255), (*it)->iX, (*it)->iY, (*it)->iX+1, (*it)->iY+1);

Do I step through the vector and use delete on the iterator?

Code:

delete (*it);

or can I use

Code:

(*vPixels).clear();

This is used for real-time video processing and objects are being created at 30Hz What is the best way to release memory that was used in making an object with new?
