Bool_t PrepareTransformation(const std::vector< Event * > &)
the identity does not need to be prepared, only calculate the normalization
void Initialize()
nothing to initialize
virtual const Event * InverseTransform(const Event *const ev, Int_t cls) const
virtual const Event * Transform(const Event *const, Int_t cls) const
identity transform returns same event
