class THnSparseArrayChunk: public TObject


 THnSparseArrayChunk is used internally by THnSparse.

 THnSparse stores its (dynamic size) array of bin coordinates and their
 contents (and possibly errors) in a TObjArray of THnSparseArrayChunk. Each
 of the chunks holds an array of THnSparseCompactBinCoord and the content
 (a TArray*), which is created outside (by the templated derived classes of
 THnSparse) and passed in at construction time.

Function documentation

THnSparseArrayChunk(Int_t coordsize, bool errors, TArray* cont)
 (Default) initialize a chunk. Takes ownership of cont (~THnSparseArrayChunk deletes it),
 and create an ArrayF for errors if "errors" is true.
~THnSparseArrayChunk()
 Destructor
void AddBin(ULong_t idx, const Char_t* idxbuf)
 Create a new bin in this chunk
void Sumw2()
 Turn on support of errors
THnSparseArrayChunk(const THnSparseArrayChunk& )
THnSparseArrayChunk& operator=(const THnSparseArrayChunk& )
THnSparseArrayChunk()
{}
void AddBinContent(ULong_t idx, Double_t v = 1.)
ULong64_t GetEntries() const
{ return fCoordinatesSize / fSingleCoordinateSize; }
Bool_t Matches(Int_t idx, const Char_t* idxbuf) const
 Check whether bin at idx batches idxbuf.
 If we don't store indexes we trust the caller that it does match,
 see comment in THnSparseCompactBinCoord::GetHash().
