point lookup:先读 fence pointer 找到 delete tile,再在 delete tile 内部遍历每个 page 的 bloomfilter 确认 key 是否在对应的 page 中,如果在就读取该 page(可能要读多个)。显然,相比 RocksDB 能按照 page 级别 fence pointer 精准定位到一个 page 的方案来说,这个
如果将B 的析构函数virtual 关键字去掉,那么B与D大小不一致,而且此时pb 已经偏移,delete pb; 先调用~B(),然后free 出错,如 *** glibc detected *** ./test: free(): invalid pointer: 0x09d0000c *** ,参照前面讲过的例子。 如果将B和D 的virtual 都去掉,B与D大小不一致,此时pb 没有偏移,delete ...
2)对于类对象数组,仅调用数组首对象的析构函数,剩下对象的空间不能被释放; 2. delete[] 释放new分配的对象数组指针指向的内存。 1)对于简单类型,效果同delete,可以释放数组内存空间; 2)对于类对象数组,将逐一调用数组中每个对象的析构函数,释放了指针指向的全部内存空间。 Top 2. 针对简单类型 1int*a =newin...
