Abstract interface to allocate and release pages.
Stores information about the cluster in which this page resides.
NTupleSize_t fIndexOffset
The first element index of the column in this cluster.
NTupleSize_t GetIndexOffset() const
RClusterInfo(NTupleSize_t id, NTupleSize_t indexOffset)
NTupleSize_t GetId() const
DescriptorId_t fId
The cluster number.
A page is a slice of a column that is mapped into memory.

void Reset(NTupleSize_t rangeFirst)
Forget all currently stored elements (size == 0) and set a new starting index.
