I don't understand what is "the STL/Charles view of iteration" and
why you don't want add my code.
In the first letter I've written just a rough template (for both
Booch and Charles) which is something like Booch, but not Booch.
Now the code for Booch (not checked for errors!):
generic
For_Container: in out BC.Containers.Container'Class;
package BC.Containers.Container_Instance is
Container: BC.Containers.Container'Class renames For_Container;
type Iterator is new BC.Containers.Iterator;
function New_Iterator return Iterator'Class;
end;
generic
For_Container: in out BC.Containers.Container'Class;
package body BC.Containers.Container_Instance is
function New_Iterator return Iterator'Class is
begin
return Iterator'Class(BC.Containers.New_Iterator(Container));
end;
end;
