Detailed Description

This class provides an interface between event filtering algorithms and athena input/output streams,.

and returns a comprehensive summary of filters "Cut Flow" by internally using T/P EventBookkeeper objects.

ICutFlowSvc also supports flat TTree format for D3PD usage.

Member Function Documentation

addEvent() [1/2]

virtual void ICutFlowSvc::addEvent ( CutIdentifier  cutID, const std::vector< float > &  weights  )

pure virtual

Tells CutFlowSvc to update the weighted event counter of a CutIdentifier A vector of weights is provided for all systematic variations.

addEvent() [2/2]

virtual void ICutFlowSvc::addEvent ( CutIdentifier  cutID, double  weight  )

pure virtual

Tells CutFlowSvc to update the weighted event counter of a CutIdentifier The same weight is for all systematic variations.

ATLAS_NOT_THREAD_SAFE()

virtual CutIdentifier registerTopFilter ICutFlowSvc::ATLAS_NOT_THREAD_SAFE ( const std::string &  name, const std::string &  description, unsigned int  logic, const std::string &  outputStream, bool  nominalOnly  )

pure virtual

Tells CutFlowSvc that a filter is used directly by an outputStream with a given logical context.

The only foreseen client should the DecisionSvc, with its Accept/Require/Veto.

DeclareInterfaceID()

		1	,
		0

getNAcceptedEvents()

virtual uint64_t ICutFlowSvc::getNAcceptedEvents ( const CutIdentifier  cutID ) const

pure virtual

Get number of accepted events for a cut.

registerCut()

virtual CutIdentifier ICutFlowSvc::registerCut ( const std::string &  name, const std::string &  description, CutIdentifier  parentCutID, bool  nominalOnly  )

pure virtual

Register cut as child of a filter in the CutFlowSvc and returns the CutID of the corresponding EventBookkeeper.

This method should be used by filters to register their internal cuts that are not the Algs themselves.

registerFilter()

virtual CutIdentifier ICutFlowSvc::registerFilter ( const std::string &  name, const std::string &  description, bool  nominalOnly  )

pure virtual

Register filter in the CutFlowSvc and returns the CutID of the corresponding EventBookkeeper.

This method should be used by filters that register themselves. Systematic variations are optional.

setFilterDescription()

virtual void ICutFlowSvc::setFilterDescription ( CutIdentifier  cutID, const std::string &  descr  )

pure virtual

Set the description of an existing EventBookkeeper.
