Detailed Description

Auxiliary class for start or end point evaluation.

Definition at line 21 of file JStart.hh.

Constructor & Destructor Documentation

JFIT::JStart::JStart ( )

inline

Default constructor.

Definition at line 25 of file JStart.hh.

             :
      Pmin1(0.0),
      Pmin2(0.0)
    {}

JFIT::JStart::JStart ( const double  Pmin1, const double  Pmin2  )

inline

Constructor.

Parameters

Pmin1	minimal probability single observation
Pmin2	minimal probability each of two consecutive observations

Definition at line 37 of file JStart.hh.

    {
      this->Pmin1 = Pmin1;
      this->Pmin2 = Pmin2;
    }

Member Function Documentation

bool JFIT::JStart::is_valid ( ) const

inline

Check validity of start or end point conditions.

Returns

true if valid; else false

Definition at line 50 of file JStart.hh.

    {
      return (Pmin1 > 0.0 && Pmin2 > 0.0);
    }

template<class JHit_t >

bool JFIT::JStart::operator() ( const JHit_t &  observation ) const

inline

Evaluate start or end point conditions.

The template parameter should correspond to a data type which has the member method:

    double getP() const;    // return probability

Parameters

observation

observation

Returns

true if start or end point; else false

Definition at line 68 of file JStart.hh.

    {
      return observation.getP() < Pmin1;
    }

template<class JHit_t >

bool JFIT::JStart::operator() ( const JHit_t &  first, const JHit_t &  second  ) const

inline

Evaluate start or end point conditions.

The template parameter should correspond to a data type which has the member method:

    double getP() const;    // return probability

Parameters

first	first observation
second	second observation

Returns

true if start or end point; else false

Definition at line 87 of file JStart.hh.

    {
      return ((first.getP() < Pmin1) ||
              (first.getP() < Pmin2 && second.getP() < Pmin2));
    }

template<class T >

T JFIT::JStart::find ( T  __begin, T  __end  ) const

inline

Get start or end point of muon trajectory.

The template parameter should correspond to a data type which has the member method:

    double getP() const;    // return probability

The input data should have been sorted along the muon path.

Parameters

__begin	begin of data
__end	end of data

Definition at line 108 of file JStart.hh.

    {
      if (__begin != __end) {
        for (T q = __begin, p = q++; q != __end; ++p, ++q) {
          if ((*this)(*p,*q)) {
            return p;
          }
        }
      }
      
      return __end;
    }

    {
      in >> parameters.Pmin1 >> parameters.Pmin2;

      return in;
    }

std::ostream& operator<< ( std::ostream &  out, const JStart &  parameters  )

friend

Write parameters to output.

Parameters

    {
      out << parameters.Pmin1 << ' ' << parameters.Pmin2;

      return out;
    }
