virtual void | Pack (void *destination, void *source, std::size_t count) const |
If the on-storage layout and the in-memory layout differ, packing creates an on-disk page from an in-memory page. | |
virtual void | Unpack (void *destination, void *source, std::size_t count) const |
If the on-storage layout and the in-memory layout differ, unpacking creates a memory page from an on-storage page. | |
