getValuePtr()

double * getValuePtr ( std::string  filterName )

inline

returns pointer to value of given filterName, nullptr if filterName has not been found.

Definition at line 176 of file FilterValueDataSet.h.

    {
      double* valuePtr = nullptr;
      auto it = m_values.find(filterName);
      if (it != m_values.end()) {
        valuePtr = &it->second;
      } else { B2WARNING("filter could not be found, returning nullptr instead!"); }
      return valuePtr;
    }

isValid()

bool isValid ( )

inline

checks if any value is still not set and returns false if that is the case.

(only completely set values in the dataSet are valid).

Definition at line 202 of file FilterValueDataSet.h.

    {
      if (expNo == std::numeric_limits<unsigned>::max()) return false;

      }
      return secIDs.isValid();
    }

reset()

void reset ( )

inline

resets all values stored to std::numeric_limits< double>::max().

and all FilterIDs to std::numeric_limits< unsigned>::max()

Definition at line 187 of file FilterValueDataSet.h.

    {
      expNo = std::numeric_limits<unsigned>::max();
      runNo = std::numeric_limits<unsigned>::max();
      evtNo = std::numeric_limits<unsigned>::max();

      secIDs.reset();
      for (auto& entry : m_values) {
        entry.second = std::numeric_limits<double>::max();
      }
    }

setValueOfFilter()

void setValueOfFilter ( std::string  filterName, double  value  )

inline

for given filterName a value is set.

if filterName does not exist, an error is produced and nothing gets stored.

Definition at line 163 of file FilterValueDataSet.h.

    {
      auto it = m_values.find(filterName);
      if (it == m_values.end()) {
        B2ERROR("FilterValueDataSet::setValueOfFilter: filterName " << filterName
                << "is not known, value " << value
                << " will NOT be added!");
        return;
