I am trying to understand the implementation of the Kaffe garbage collector. The first step of the Mark phase there is to wall all root Objects and mark them as grey. Could anybody tell me what do we mean by root Objects or root set etc. and why do we start marking from them.

The file gcRefs.c defines two functions:gc_add_ref and gc_rm_ref,the first one add a persistent reference to an object (stored in a hashtable ),the next function remove a persistent reference to an object. I know many functions invoke gc_add_ref to add a references to an object,but I hardly find corresponding invoking about gc_rm_ref . I want to know,how garbage collector (or kaffe ?) maintain it's hashtable of root references object(not only add,but also delete) ? thanks
