Detailed Description

template<class Ntuple, class T = Int_t>
class NTFillIterator< Ntuple, T >

A FillIterator from an ntuple variable.

An NTFillIterator collaborates with a class Ntuple, which automatically generated by TTree::MakeClass. The branch name given must correspond to an Int_t that represent the number of entries (jets, tracks, whatever) over which one wants to iterate.

The first template argument is the class name of the ntuple class that was automatically generated by TTree::MakeClass. The second (optional) template argument is the type of the branch variable; this is useful if the branch contains not Int_t objects, but short or char values.

Public Member Functions
	NTFillIterator (const Ntuple &nt_, const char *branchname)
	Constructor using a branch name.
	NTFillIterator (const Ntuple &nt_, T Ntuple::*p_mem, const char *objectname="?")
	Constructor using a member pointer.
virtual int	operator() () const
	Returns iterator value, starting at 0; "-1" means "invalid".
virtual bool	next ()
	Increments iterator; returns false if iterator cannot be incremented.
virtual bool	reset ()
	Resets iterator; returns false if iterator value range is empty.
virtual bool	isValid () const
	Returns whether current value of iterator is valid.
Protected Member Functions
virtual	~NTFillIterator ()
	Protected destructor ensures creation on the heap.
Protected Attributes
const Ntuple &	nt
	The ntuple.
const T *	branchAddress
	The branch adress.
int	index
	The current index value.
