ROOT::Experimental::Detail::RPageStorage::RSealedPage Struct Reference

A sealed page contains the bytes of a page as written to storage (packed & compressed).

It is used as an input to UnsealPages() as well as to transfer pages between different storage media. RSealedPage does not own the buffer it is pointing to in order to not interfere with the memory management of concrete page sink and page source implementations.
