Protected Attributes inherited from ROOT::RClusterDescriptor::RPageInfo
bool	fHasChecksum = false
	If true, the 8 bytes following the serialized page are an xxhash of the on-disk page data.
RNTupleLocator	fLocator
	The meaning of fLocator depends on the storage backend.
std::uint32_t	fNElements = std::uint32_t(-1)
	The sum of the elements of all the pages must match the corresponding fNElements field in fColumnRanges.
