RE: [CFCDev] memento and composition

[Justin Balog]

Sorry Barney, for being completely thick skulled, but 'a' in the init() is
passed in.  When I am going to call the setInstanceMemento() of the person,
I won't be passing in an 'a' to the init() so there won't be an 'a'
available to whose setInstanceMemento(m.address) I can call. I think I am
missing something here.  Thanks again.

Justin

The methods will be different, as they are doing different things.  In
effect, you have two separate means of setting the address: directly, and as
part of a memento.  Here are a few likely methods:

void init(String name, Address a) {
  setName(name);
  setAddress(a);
}

void setName(String name) {
  variables.instance.name = name;
}

void setAddress(Address a) {
  variables.instance.address = a;
}

String getName() {
  return variables.instance.name;
}

Address getAddress() {
  return variables.instance.address;
}

void setMemento(m) {
  setName(name);
  variables.instance.address.setMemento(m.address);
}

struct getMemento() {
  var result = structNew();
  result.name = getName();
  result.address = variables.instance.address.getMemento();
  return result;
}
