Hi Kaly

Welcome to the ranch.

I'm not sure I understand your question a bit more detail will help us be more specific. But that won't stop me from guessing what you mean.

There is a clone method defined for many objects. You will have to override it to make sure it's complete for your objects. When I googled for a good link for you I saw many hits saying don't use it without considering the consequences.

However if I understand what your question is it seems appropriate.

something like:



or


Note that just assigning temp=in will just add another reference to the same object so changing one changes both.

It's not what your program can do, it's what your users do with the program.
