10 * Description: *
11 * Concrete PDEFoam sub-class. This foam stores the first target *
12 * (index 0) with every cell, as well as the statistical error on *
13 * the target. *

Bool_t CellValueIsUndefined(PDEFoamCell *cell)
Returns true, if the target error equals -1, as set in Finalize() in case of no events in the cell.
PDEFoamTarget()
Default constructor for streamer, user should not use it.
virtual void Finalize()
Calculate average cell target in every cell and save them to the cell.
virtual void FillFoamCells(const Event *ev, Float_t wt)
This function fills an event into the discriminant PDEFoam.
virtual Float_t GetCellValue(const std::vector< Float_t > &xvec, ECellValue cv, PDEFoamKernelBase *)
This function finds the cell, which corresponds to the given untransformed event vector 'xvec' and re...
Float_t GetAverageNeighborsValue(std::vector< Float_t > &, ECellValue)
This function returns the average value 'cv' of only nearest neighbor cells.
