[ns] create-shadow

[Andrea Josi <mr_josi@yahoo.it>]

Hi all,
i am still trying to understand the interactions
between c++ and otcl;

in the manual (again, chap 3) it is said that the
TclObject constructor is "responsible for setting up
the shadow object", using the "create-shadow" method:
actually there is a call to such a method in the 
"~tclcl/tcl-object.tcl SplitObject instproc init "
method but

* where is this method defined ? 
What is the meaning of "setting up" ? 

* for instance, are new varibles created or is there
some kind of linkage such as the one that is performed
by the command method?  

* if i implement a protocol using only OTCL, what
effect does the create-shadow method have ? is then
any interaction with c++ ?


Thanks in advance.
