Methods of Copying
The design goal of most objects is to give the semblance of being made out of one monolithic block even though most are not. As objects are made up of several different parts, copying becomes nontrivial. Several strategies exist to attack this problem.
Consider two objects, A and B, which each refer to two memory blocks xi and yi (i = 1, 2,...). Think of A and B as strings and of xi and yi (i = 1, 2,...) as the characters they contain. There are different strategies for copying A into B.
