THnSparseT< CONT > Class Template Reference

template<class CONT>
class THnSparseT< CONT >

Templated implementation of the abstract base THnSparse.

All functionality and the interfaces to be used are in THnSparse!

THnSparse does not know how to store any bin content itself. Instead, this is delegated to the derived, templated class: the template parameter decides what the format for the bin content is. In fact it even defines the array itself; possible implementations probably derive from TArray.

Typedefs exist for template parameters with ROOT's generic types:

Templated name Typedef Bin content type
THnSparseT<TArrayC> THnSparseC Char_t
THnSparseT<TArrayS> THnSparseS Short_t
THnSparseT<TArrayI> THnSparseI Int_t
THnSparseT<TArrayL> THnSparseL Long_t
THnSparseT<TArrayF> THnSparseF Float_t
THnSparseT<TArrayD> THnSparseD Double_t

We recommend to use THnSparseC wherever possible, and to map its value space of 256 possible values to e.g. float values outside the class. This saves an enormous amount of memory. Only if more than 256 values need to be distinguished should e.g. THnSparseS or even THnSparseF be chosen.

Implementation detail: the derived, templated class is kept extremely small on purpose. That way the (templated thus inlined) uses of this class will only create a small amount of machine code, in contrast to e.g. STL.
