class RooGrid: public TObject, public RooPrintable

 Default constructor

 Constructor with given function binding

 Destructor

 Calculate and store the grid dimensions and volume using the
 specified function, and initialize the grid using a single bin.
 Return kTRUE, or else kFALSE if the range is not valid.

 Adjust the subdivision of each axis to give the specified
 number of bins, using an algorithm that preserves relative
 bin density. The new binning can be finer or coarser than
 the original binning.

 Reset the values associated with each grid cell.

 Generate a random vector in the specified box and and store its
 coordinates in the x[] array provided, the corresponding bin
 indices in the bin[] array, and the volume of this bin in vol.
 The box is specified by the array box[] of box integer indices
 that each range from 0 to getNBoxes()-1.

 Reset the specified array of box indices to refer to the first box
 in the standard traversal order.

 Update the specified array of box indices to refer to the next box
 in the standard traversal order and return kTRUE, or else return
 kFALSE if we the indices already refer to the last box.

 Print info about this object to the specified stream.

 Print name of grid object

 Print title of grid object

 Print class name of grid object

 Add the specified amount to bin[j] of the 1D histograms associated
 with each axis j.

 Refine the grid using the values that have been accumulated so far.
 The parameter alpha controls the stiffness of the rebinning and should
 usually be between 1 (stiffer) and 2 (more flexible). A value of zero
 prevents any rebinning.

 Accessor for the j-th normalized grid point along the i-th dimension
