What happens to the alocated memory of objects such as graphics primatives when their variable are assigned new values? For example, suppose I have a thousand pairs of triple which I use to create a thousand Line objects. If I then change the values of all the tripples, and create new Lines assigning them to the same variables I used to store the original Lines, what happens to the memory that held the original lines?
