Detailed Description

template<class T, class CO>
class AlgorithmCalibration< T, CO >

The AlgorithmCalibration class is the interface between user code and calibration framework developed for BReco subsytem. Both the analysis programs and the calibration programs should only access calibration information via that class.

An algorithm is supposed to keep a single instance of that class to avoid the reload of XML for every event (during analysis) and because you want to accumulate over all events the data to perform a new calibration in the calibration program.

The class is templated on the Category T and on the CalibratedObject CO
