[kepler-dev] Actor's class name?

[DONGHOON KIM]

Hi Christopher,

Thank you for your answers to my questions!

What about the name of the container (i.e., _container)?
When I debugged, I have found that the value of " _container" (red box in
the attached pic) is "StringConst".
If this value is also unique, I want to extract this value instead of the
full qualified classname.
lastIndexOf() may need extra work to extract the value "StringConst".
Do you know any other function to extract the value "StringConst"? maybe...
getUnderBarContainer.
but I can not find that function in source code.

Please, let me know

Thank you

-Donghoon
