Detailed Description

Class for storing a number of floats (Flt) and functions on those.

Author

Nils Gollub nils..nosp@m.goll.nosp@m.ub@ce.nosp@m.rn.c.nosp@m.h

This class implements the infrastructure to store a (variable) number of floats for each channel or ADC. The stored floats can be used to define a function of one parameter. Different functional forms can be implemented and differentiated by the objVersion header variable (this allows for e.g. schema evolution). The functions are evaluated by calling the getCalib() function.

Member Typedef Documentation

DefType

typedef std::vector<std::vector<float> > CaloCondBlobDat< float >::DefType

inherited

Object to hold default data used for initialization.

The length of the outer and inner vector determines respectively the number of gains and values per gain to be stored. The indexing is thus DefType[iGain][iValue].
