如何在Smalltalk中按类获取超类的名称

Question

I know how to get a metaclass of a class in SMALLTALK (with class message ) .

But how do i get the SuperClass of a class (or get the SuperClass of an instance of some class )?

Answer 1

Using instance class superclass , of course! Every class can answer its (unique) superclass.

However, note that you have several capitalization mistakes that are not innocent. In Smalltalk, capitalization rules are meaningful, beyond case-sensitivity.

Also, it is uncommon to cross the instance-class level to query something like this. Usually, only meta-programming tools (debuggers, inspectors) have questions like this.
