Detailed Description

Just a marker to denote that the memory region represents a data page.

We don't instantiate this object nor derive from this. This is just a marker. Because derived page objects have more header properties and even the data_ is layed out differently. We thus make everything private to prevent misuse.

Attention

Remember, anyway we don't have RTTI for data pages. They are just byte arrays used with reinterpret_cast.
