Member Function Documentation

addEntry() [1/2]

void addEntry	(	WeightInfo	entryValue,
		NDBin	bin
	)

Adds entry to the LookUp table and also adds entry to key table if needed.

Parameters

entryValue	is a line from LookUp table
bin	contains bin limits for given LookUp table values

Definition at line 16 of file ParticleWeightingLookUpTable.cc.

{
  int id = m_WeightMap.size();
  this->addEntry(std::move(entryValue), std::move(bin), id);
}

addEntry() [2/2]

void addEntry	(	WeightInfo	entryValue,
		NDBin	bin,
		int	key_ID
	)

Adds entry to the LookUp table and also adds entry to key table with predefined bin ID if needed.

Parameters

entryValue	is a line from LookUp table
bin	contains bin limits for given LookUp table values
key_ID	is bin ID. You might want to use it to make several bins with the same ID or for non-square bins.

Definition at line 22 of file ParticleWeightingLookUpTable.cc.

{
  int id = m_KeyMap.addKey(std::move(bin), key_ID);
  entryValue.insert(std::make_pair("binID", id));
  m_WeightMap.insert(std::make_pair(id, entryValue));
}

defineOutOfRangeWeight()

void defineOutOfRangeWeight

(

const WeightInfo &

entryValue

)

Define reweight info for particles out of range.

This info is stored in bin -1.

Parameters

entryValue

is a line from LookUp table

Definition at line 30 of file ParticleWeightingLookUpTable.cc.

{
  m_WeightMap.insert(std::make_pair(m_OutOfRangeBinID, entryValue));
}

getAxesNames()

std::vector< std::string > getAxesNames

(

)

const

Get axes names.

Returns

vector of axes names

Definition at line 36 of file ParticleWeightingLookUpTable.cc.

{
  return m_KeyMap.getNames();
}

getInfo()

WeightInfo getInfo

(

std::map< std::string, double >

values

)

const

Get axes names.

Parameters

values

map of axes names with values along corresponding names

Returns

vector of axes names

Definition at line 41 of file ParticleWeightingLookUpTable.cc.

{
  int id = m_KeyMap.getKey(std::move(values));
  auto it = m_WeightMap.find(id);
  if (it != m_WeightMap.end()) {
    return  m_WeightMap.at(id);
  } else {
    B2FATAL("Attempt to access undeclared bin");
    return m_WeightMap.at(m_OutOfRangeBinID);
  }
}

printParticleWeightingLookUpTable()

void printParticleWeightingLookUpTable

(

)

const

Print content of LookUpTable.

  m_KeyMap.printKeyMap();
  B2INFO("Printing the table");
  for (const auto& entry : m_WeightMap) {
    int key_ID = entry.first;

    std::string bin_id = "";
    for (const auto& line : info) {
      bin_info += line.first + " " + std::to_string(line.second) + " ; ";
    }
    if (key_ID == m_OutOfRangeBinID) {
      bin_id += "Out of range bin " + std::to_string(key_ID) + " : ";
    } else {
