[QuantLibAddin-developers] Revised Processing of Instance Names

[eric e. <eri...@gm...>]

Hi All,

In order to facilitate some additional developments on ObjectHandler
I've made further refinements to the processing of instance names
(handles).  These changes are consistent with the various requirements
that people have told me about but if the changes cause any problems
please let me know.

1) The user is now required to ensure that his instance names are
unique.  If a user tries to instantiate two different objects called
"foo" the second attempt fails (with an appropriate message written to
the log).
2) The hidden name that is assigned to the the calling cell for
purposes of garbage collection - e.g. "~_00000" - is no longer
suffixed to the instance name
3) An update counter in the format "#0000" is appended to the instance
name for display purposes only, unlike the old "~_00000" key mentioned
above this counter does not become part of the instance name as used
to key the internal map of objects
4) If the user supplies an empty string as the instance name then a
name is generated automatically in the format "obj_xxxx#0000" where
xxxx is an arbitrary unique value and #0000 is the update counter.

Eric
