Detailed Description

template<typename InfType>
class Belle2::LowerBoundedSet< InfType >

Represents a lower bounded set of arithmetic types.

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

Member Function Documentation

contains()

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 open set ( m_inf, infinity )

Definition at line 46 of file LowerBoundedSet.h.

{ return  m_inf < x ;};

getInf()

InfType getInf ( void  ) const

inline

Accessor to the inf of the set.

Definition at line 79 of file LowerBoundedSet.h.

{ return m_inf; } ;

getNameAndReference()

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 86 of file LowerBoundedSet.h.

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

persist()

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

inline

Creates and sets the addresses of the leaves to store the inf value.

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 "_inf" suffix for the inf value.

Definition at line 57 of file LowerBoundedSet.h.

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

setBranchAddress()

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

inline

Setting the branch address for a filter in a TTree.

Parameters

t	: the TTree in which the branch address shall be set
branchName	: name of the branch

Definition at line 72 of file LowerBoundedSet.h.

    {
      if (t->SetBranchAddress(branchName, & m_inf) < 0) B2FATAL("LowerBoundedSet: branch address not valid");
    }
