function Cutflow #

inline Cutflow()

Default constructor.

Does nothing! Just to allow storage in STL containers and use as a member variable without using the init list

function Cutflow #

inline Cutflow(
    const string & cfname,
    const vector< string > & cutnames
)

Proper constructor.

function fillinit #

inline void fillinit(
    double weight =1.
)

Fill the pre-cut counter.

function fill #

inline bool fill(
    size_t icut,
    bool cutresult =true,
    double weight =1.
)

Fill the {icut}’th post-cut counter, starting at icut=1 for first cut.

Note: Returns the cut result to allow ‘side-effect’ cut-flow filling in an if-statement

function fill #

inline bool fill(
    size_t icut,
    double weight
)

Fill the {icut}’th post-cut counter, starting at icut=1 for first cut (cutvalue=true overload)

Note: Returns the cut result to allow ‘side-effect’ cut-flow filling in an if-statement

This version exists to allow calling fill(i, weight) without the weight getting cast to a bool, or having to explicitly add a ’true’ middle arg.

function fill #

inline bool fill(
    size_t icut,
    const vector< bool > & cutresults,
    double weight =1.
)

Fill cut-state counters from an n-element results vector, starting at icut.

Note: Returns the overall cut result to allow ‘side-effect’ cut-flow filling in an if-statement

function fillall #

inline bool fillall(
    const vector< bool > & cutresults,
    double weight =1.
)

Fill all cut-state counters from an Ncut-element results vector, starting at icut=1.

function fillnext #

inline bool fillnext(
    bool cutresult,
    double weight =1.
)

Fill the next post-cut counter.

Note: Returns the cut result to allow ‘side-effect’ cut-flow filling in an if-statement

function fillnext #

inline bool fillnext(
    double weight =1.
)

Fill the next post-cut counter, assuming a true result.

Note: Returns the cut result to allow ‘side-effect’ cut-flow filling in an if-statement

function fillnext #

inline bool fillnext(
    const vector< bool > & cutresults,
    double weight =1.
)

Fill the next cut-state counters from an n-element results vector.

Note: Returns the cut result to allow ‘side-effect’ cut-flow filling in an if-statement

function filltail #

inline bool filltail(
    const vector< bool > & cutresults,
    double weight =1.
)

Fill the N trailing post-cut counters, when supplied with an N-element results vector.

Deprecated:

Now prefer to use vector fillnext()

Note: Returns the overall cut result to allow ‘side-effect’ cut-flow filling in an if-statement

The cutresults vector represents the boolean results of the last N cuts. This function allows mixing of cut-flow filling with higher-level analyze() function escapes such as the vetoEvent directive. The initial state (state 0) is not incremented.

function scale #

inline void scale(
    double factor
)

Scale the cutflow weights by the given factor.

function normalize #

inline void normalize(
    double norm,
    size_t icut =0
)

Scale the cutflow weights so that the weight count after cut icut is norm.

function str #

inline string str() const

Create a string representation.

function print #

inline void print(
    std::ostream & os
) const

Print string representation to a stream.
