Constructor & Destructor Documentation

◆ JChainReader() [1/3]

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();
     }

◆ JChainReader() [2/3]

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();
     }

◆ JChainReader() [3/3]

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())
     {
       configure();
     }

Member Function Documentation

◆ Reset()

template<class T>

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

inline

Reset this TChain.

This method executes the following steps:

TChain::Reset();
releases the allocated memory and resets the internal pointer;
SetBranchAddress();

Parameters

option option

Definition at line 78 of file JChainReader.hh.

     {
       TChain::Reset(option);
  
       this->release();
       
       this->SetBranchAddress(this->getBranchName(), &this->address);
     }

◆ configure()

template<class T>

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

inlineprotected

Configure this TChain.

Definition at line 92 of file JChainReader.hh.

     {
       this->SetNameTitle(this->getTreeName(), this->getTreeTitle());
  
       this->SetBranchAddress(this->getBranchName(), &this->address);
     }

◆ release()

template<class T>

void JROOT::JRootAddress< T >::release ( )

inlineinherited
