Closures and oops_do
The GC uses C++ objects called closures to traverse managed pointers (aka "oops")...
Finding roots
Live objects are defined as those which are reachable from a set of root references. Each root reference is presented to the GC as the address of an oop, usually in a thread stack or static global structure.
Strong roots are located using ...
Rules for strong root traversal
- each root location must be visited exactly once
- if the GC has multiple phases, the roots visited by each phase must be consistent
- ...
