Detailed Description

This is a base class to store weight information in a way that allows unified access in the structure that contains all event generation weights information (WeightContainer below). The main purpuse of this class is to supply convenience features to make defining new categories of weights easy. All weights should inherit from this base class. The specialized classes may then contain specialized functions, or only act as a glorified book-keeping structure.

Member Function Documentation

virtual void bookVectors	(	vector< double >	weights,
		vector< string >	names
	)

inlinevirtual

Store the current event information (replace whitespace with underscore for HepMC).

Reimplemented in WeightsLHEF, and WeightsMerging.

void bookWeight	(	string	name,
		double	defaultValue = `1.`
	)

inline

Function to create a new, synchronized, pair of weight name and value.

Check if name already exists.

void collectWeightValues	(	vector< double > &	outputWeights,
		double	norm = `1.`
	)

virtual

WeightsBase class.

Function to return processed weights to weight container, e.g. if weights should be combined before proceeding.

Reimplemented in WeightsFragmentation, WeightsLHEF, WeightsMerging, and WeightsSimpleShower.

int findIndexOfName ( string name )

inline

Function to find the index of a given entry in the weightNames vector, e.g., to be able to synchronize with the weightValues vector.

string getWeightsName ( int iPos ) const

inline

Get the stored information. Direcly use storage members here in the base class, and access those through non-virtual getters. Note: NOT opting for a map data structure, since information will anyway have to be serialized in output. Change weight names for compatibility with Rivet by replacing colons with full stops.

void parse	(	string	wvecKey,
		map< string, map< string, double > > &	dct
	)

protected

Parse a WVec of variations into a dictionary.

Parse a WVec of variations into a weight group map.

Skip blank lines and remove leading spaces.

Separate line by spaces, and read key/value pairs.

virtual void reweightValueByName	(	string	name,
		double	val
	)

inlinevirtual

Use existing functions: Find index of name, then set by index.

Reimplemented in WeightsMerging.
