Ok, so I understand from your answer that only one instance of Egg object is allocated in the program static memory area, even when an egg class object is a member of that class.

is(n) [incr Tcl] is(n) __________________________________________________________________________________________________________________________________________________ NAME
is - test argument to see if it is a class or an object SYNOPSIS
itcl::is option ?arg arg ...? _________________________________________________________________ DESCRIPTION
The is command is used to check if the argument given is a class or an object; depending on the option given. If the argument if a class or object, then 1 is returned. Otherwise, 0 is returned. The is command also recognizes the commands wrapped in the itcl code command. The option argument determines what action is carried out by the command. The legal options (which may be abbreviated) are: is class command Returns 1 if command is a class, and returns 0 otherwise. The fully qualified name of the class needs to be given as the command argument. So, if a class resides in a namespace, then the namespace needs to be specified as well. So, if a class C resides in a namespace N, then the command should be called like: is N::C or is ::N::C is object ?-class className? command Returns 1 if command is an object, and returns 0 otherwise. If the optional "-class" parameter is specified, then the command will be checked within the context of the class given. Note that className has to exist. If not, then an error will be given. So, if className is uncertain to be a class, then the programmer will need to check it's existance beforehand, or wrap it in a catch statement. So, if c is an object in the class C, in namespace N then these are the possibilities (all return 1): set obj [N::C c] itcl::is object N::c itcl::is object c itcl::is object $obj itcl::is object [itcl::code c] KEYWORDS
