JVM垃圾回收一节中动态年龄计算表述有误

10

正确的表述应该是：“Hotspot遍历所有对象时，按照年龄从小到大对其所占用的大小进行累积，当累积的某个年龄大小超过了survivor区的一半时，取这个年龄和MaxTenuringThreshold中更小的一个值，作为新的晋升年龄阈值”。 **动态年龄计算的代码如下** ``` uint ageTable::compute_tenuring_threshold(size_t survivor_capacity) { //survivor_capacity是survivor空间的大小 size_t desired_survivor_size = (size_t)((((double) survivor_capacity)*TargetSurvivorRatio)/100); size_t total = 0; uint age = 1; while (age < table_size) { total += sizes[age];//sizes数组是每个年龄段对象大小 if...
