Detailed Description

template<class T>
class NAIA::SkimTreeHandle< T >

Helper class to ease skimming operations.

This class is meant to automate most of the work when the user has to skim a tree from an existing NAIA file. It will automatically setup the branches in the new tree.

Template Parameters

T

Constructor & Destructor Documentation

SkimTreeHandle()

template<class T >

NAIA::SkimTreeHandle< T >::SkimTreeHandle ( std::unique_ptr< TFile >  outFile, std::unique_ptr< T >  chain, T *  originalChain  )

inline

Construct a new SkimTreeHandle.

Used internally. SkimTreeHandles should always be created by the parent NAIAChain

Parameters

outFile	The rootfile where the new tree will be resident
chain	The new NAIA chain to be filled
originalChain	The original NAIA chain from which events will be copied
