Detailed Description

Represents one data page in Array Storage.

This is a private implementation-details of Array Storage, thus file name ends with _impl. Do not include this header from a client program unless you know what you are doing.

Attention: Do NOT instantiate this object or derive from this class. A page is always reinterpret-ed from a pooled memory region. No meaningful RTTI.
