摘要：
In a generational, copying garbage collector, young generation collection may be made more efficient by dynamically measuring object survival rates as a function of “fine-grained” allocation age, and choosing, on the basis of these survival rates, part of the young generation that will be not be collected, but instead scanned for pointers to objects in the rest of the young generation. The rest of the young generation, including objects referenced by the pointers, is then collected.
