Constructor & Destructor Documentation

template<class T>

JROOT::JChainReader< T >::JChainReader ( )

inline

Default constructor.

Note that the default TTree parameters are obtained using template method JROOT::getTreeParameters.

Definition at line 35 of file JChainReader.hh.

                   :
      JTreeParameters(JROOT::getTreeParameters<T>())
    {
      configure();
    }

template<class T>

JROOT::JChainReader< T >::JChainReader ( const JTreeParameters &  parameters )

inline

Constructor.

Parameters

parameters

parameters of TTree

Definition at line 47 of file JChainReader.hh.

                                                    :
      JTreeParameters(parameters)
    {
      configure();
    }

template<class T>

JROOT::JChainReader< T >::JChainReader ( const JChainReader< T > &  reader )

inline

Copy constructor.

Note that the TTree parameters are copied but not the contents.

Parameters

reader

TChain reader

Definition at line 61 of file JChainReader.hh.

                                                :
      JTreeParameters(reader.getTreeParameters())

Member Function Documentation

template<class T>

void JROOT::JChainReader< T >::Reset ( Option_t *  option = NULL )

inline

Reset this TChain.

This method executes the following steps:

1. TChain::Reset();
2. releases the allocated memory and resets the internal pointer;
3. SetBranchAddress();

Parameters

option

option
