class TMVA::PDEFoamKernelLinN: public TMVA::PDEFoamKernelBase

 Default constructor for streamer

 Copy constructor

 Linear neighbors kernel estimator.  It returns the cell value
 'cv', corresponding to the event vector 'txvec' (in foam
 coordinates) linear weighted by the cell values of the neighbor
 cells.

 Parameters:

 - foam - the pdefoam to search in

 - txvec - event vector in foam coordinates [0,1]

 - cv - cell value to estimate

 Returns the cell value, corresponding to 'txvec' (foam
 coordinates [0,1]), weighted by the neighbor cells via a linear
 function.

 Parameters:
  - foam - the foam to search in

  - txvec - event vector, transformed into foam coordinates [0,1]

  - cv - cell value to be weighted

  - TreatEmptyCells - if this option is set to false (default),
    it is not checked, wether the cell value or neighbor cell
    values are undefined (using foam->CellValueIsUndefined()).
    If this option is set to true, than only non-empty neighbor
    cells are taken into account for weighting.  If the cell
    value of the cell, which contains txvec, is empty, than its
    value is estimated by the average value of the non-empty
    neighbor cells (using GetAverageNeighborsValue()).

 This function returns the average value 'cv' of only nearest
 neighbor cells.  It is used in cases when a cell value is
 undefined and the cell value shall be estimated by the
 (well-defined) cell values of the neighbor cells.

 Parameters:
 - foam - the foam to search in
 - txvec - event vector, transformed into foam coordinates [0, 1]
 - cv - cell value, see definition of ECellValue
