9 // AliTPCInverseCorrection class //
11 // This is a wrapper that inverts an AliTPCCorrection. This is done by //
12 // swapping the CalculateCorrection and CalculateInverseCorrection functions. //
13 // The wrapped correction is supplied as a pointer and the class relies //
14 // on the fact, that this pointer keeps pointing to the right object. //
15 // However, the ownership is not changed, i.e. the wrapped correction //
16 // will not be deleted when this correction is destructed. //
