【Mark-and-sweep algorithm】 This algorithm reduces the definition of "an object is not needed anymore" to "an object is unreachable". 从"an object is not needed anymore" 进化到 "an object is unreachable". This algorithm assumes the knowledge of a set of objects calledrootsPeriodically, the...
操作1,检测所有不可达对象;步骤2,回收不可达对象所占用的堆内存。 Mark and Sweep Algorithm(标记清除算法)在下面两个阶段执行这两个操作: 1)Mark phase(标记阶段) 2)Sweep phase(清除阶段) Mark phase(标记阶段) 在对象创建时,设置它的标记位为0(false)。在Mark phase(标记阶段),我们设置所有可达对象的标记...

The second step, sweep, involves scanning the sea for any object that is not marked. As you can readily determine, the mark and sweep algorithm seems effective, but probably not very efficient due to the two-step nature of this approach. This eventually lead to a Java garbage collection sys...

Apologies for asking here if this is not the correct place. In your memory guidelines, you discuss the possibility of future work on an incremental mark-and-sweep algorithm for garbage collection. Have you given this any further thought?...
Concurrent Mark-Sweep (CMS) Collector is actually a combination of two garbage collectors: The Parallel New (ParNew) Collector of Young generation - It uses the 3-area (Eden, Survivor Space "From" and Survivor Space "To") algorithm parallelly with multiple threads in a stop-the-world fashion...
Warning:this part is very C++ specific and is low-level. In general, the following implementation details can be skipped and are not required for understanding the Mark-Sweep algorithm itself. Proceed only on your interest. Aroot, as we know, is a reachable alive reference, which usually is...
