Member Function Documentation

void GGSTRngStateReader::GetEntry ( Long64_t  entry )

virtual

@ brief Reads the specified entry from the random engine state branch.

Parameters

entry

The desired entry.

Implements GGSTChainReader.

Definition at line 27 of file GGSTRngStateReader.cpp.

                                                {
  if (entry != _rngStateChain->GetEntries()) {
    _rngStateChain->GetEntry(entry);
  }
}

const std::string GGSTRngStateReader::GetName

(

)

Gets the name of the random number generator for the current event.

Returns

The random number generator name.

                                            {
  if (_rngName == "") {
    if (_rngStateChain) {
      TKey *key = _rngStateChain->GetFile()->GetKey("rngName");
      if (key) {
        _rngName = *((std::string *)(key->ReadObjectAny(TClass::GetClass("std::string"))));
      }
    }
  }
  return _rngName;
}

const std::string GGSTRngStateReader::GetState ( )

inline

Gets the state of the random number generator for the current event.

Returns

The random number generator state.

Definition at line 41 of file GGSTRngStateReader.h.

{ return *_rngState; }

bool GGSTRngStateReader::SetChain ( TChain *  rngStateChain )

virtual

Sets the chain.

This method sets the random engine state chain, from which the informations will be read.

Parameters

rngStateChain

The chain containing the random engine state branch.

Implements GGSTChainReader.

                                                       {

  _rngStateChain = rngStateChain;
  if (_rngStateChain->SetBranchAddress("rngState", &_rngState) == 0) {
    return true;
  } else {
    return false;
  }
