Does,unified type system or single rooted hierarchy help for doing Garbage collection and if so how?

推荐答案

垃圾收集器唯一需要的是能够识别对象的大小以及对象中引用的位置(例如，根据类型)

The only thing which a garbage collector needs is to be able to identify the size of an object and where the references in the object are (e.g. from the type)

拥有一种确定方法，可以使其变得更加简单.

Having one way of determining this, can make it much simpler.
