Detailed Description

template<class T>
class CaloCondBlobDat< T >

Generic template class for storing a number of "T"s for each channel/gain.

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 Ts for each channel/gain. Only types that are a multiple of uint32_t can be stored, i.e. float, uint32_t, uint64_t, etc... The number of Ts to store is encoded in the objSize header variable. The object version header variable has no meaning for this class (since schema evolution does not make sense here) and is always set to 0.

Member Typedef Documentation

DefType

template<class T>

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

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].
