                                                                  {

  GGSTPrimaryDisInfo *interaction;
  for (int i = 0; i < _disInfo->GetEntries(); i++) {
    interaction = (GGSTPrimaryDisInfo *)(_disInfo->At(i));
    if (interaction->primary.trackID == trackID) {
      return interaction;
    }
  }

  return nullptr;
}

@ brief Reads the specified entry from the primary disappearance information branch.

Parameters

entry

The desired entry.

Implements GGSTChainReader.

Definition at line 26 of file GGSTPrimaryDisReader.cpp.

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

bool GGSTPrimaryDisReader::SetChain ( TChain *  disInfoChain )

virtual

Sets the chain.

This method sets the disappearance info chain, from which the informations will be read.

Parameters

disInfoChain

The chain containing the primary disappearance information.

Implements GGSTChainReader.
