Detailed Description

template<typename MaxType>
class Belle2::ClosedUpperBoundedSet< MaxType >

Represents an upper bounded set of arithmetic types.

UpperBoundedSet is used in conjunction with the SelectionVariable to define one of the building blocks of the Filters

Member Function Documentation

contains()

template<typename MaxType>

template<class VariableType>

bool contains ( const VariableType & x ) const

inline

Method used by the filter tools to decide on the fate of the pair.

Parameters

x	is the result of some SelectionVariable applied to a pair of objects. The return value is true if x belongs to the closed set [ -infinity, m_max ]

Definition at line 49 of file ClosedUpperBoundedSet.h.

{ return x <= m_max;};

getNameAndReference()

template<typename MaxType>

std::string getNameAndReference ( std::vector< std::pair< char, void * > > * pointers = nullptr, const std::string & varname = "X" )

inline

generates a "name" and fills the vector with the variable references

Parameters

pointers	pointer to vector which contains a pair of char which indicates the type object pointed to and the actual pointers to the bounds, if equal to nullptr it will not be filled
varname	optional name of the filter this range is attached to make the output look nicer

Definition at line 92 of file ClosedUpperBoundedSet.h.

    {
      std::string maxVal = std::to_string(m_max);
      // if pointer to vector is provided fill it
      if (pointers != nullptr) {
        // use the position in the vector as unique identifier
        maxVal = "#" + std::to_string(pointers->size());
        (*pointers).push_back({TBranchLeafType(m_max), &m_max});
      }
      return ("(" + varname + " <= " + maxVal + ")");
    }

getSup()

template<typename MaxType>

MaxType getSup ( void ) const

inline

Accessor to the sup of the set (which is also the max)

Definition at line 84 of file ClosedUpperBoundedSet.h.

{ return m_max; } ;

persist()

template<typename MaxType>

void persist ( TTree * t, const std::string & branchName, const std::string & variableName )

inline

Creates and sets the addresses of the leaves to store the min and max values.

Parameters

t	the pointer to the TTree that will contain the TBranch of this range.
branchName	the name of the TBranch that will host this range.
variableName	the name of the selection variable this range is applied to.

The leaves will be named as the selection variable name with the "_max" suffixes for the m_max value.

Definition at line 61 of file ClosedUpperBoundedSet.h.

    {
 
      std::string leafList;
      leafList += variableName;
      leafList += "_max/";
      leafList += TBranchLeafType(m_max);
 
      TBranch* branch = new TBranch(t, branchName.c_str(), & m_max, leafList.c_str());
      t->GetListOfBranches()->Add(branch);
    }

setBranchAddress()

template<typename MaxType>

void setBranchAddress ( TTree * t, const std::string & branchName, const std::string &  )

inline

Set the branch address of the specified leafes to the data members.

Parameters

t	tree for which the Branch addresses will be set
branchName	name of the branch

Definition at line 77 of file ClosedUpperBoundedSet.h.

    {
      if (t->SetBranchAddress(branchName.c_str(), & m_max) < 0) B2FATAL("ClosedUpperBoundedSet: branch address not valid!");
    }
