Smalltalk超类vs元类? [英] Smalltalk superclass vs metaclass?

问题描述

我是OOP的新手，但是具有过程"背景.

I new to OOP, but with a "procedural" background.

我目前正在尝试通过GNU Smalltalk和Lovejoy的"Smalltalk:获取消息"来了解OOP.

I'm currently trying to get my head around OOP via GNU Smalltalk and Lovejoy's "Smalltalk: Getting The Message".

对于元类和元类类与超类之间的关系，我感到困惑.我可以看到超类->类->子类的继承流程；但我看不到元类的适合方式/位置.TIA ...

I'm confused as to the the heck the metaclass and Metaclass class are, vs superclass. I can see the inheritance flow of superclass -> class -> subclass; but I don't see how/where metaclass fits in. TIA...
