ResetColumns() - reset the list of columns of interest. Add/RemoveColum( namCol ) - try to add/remove column with name namCol to/from the list. SetColumnStatus ( namCol, status ) - mostly for UI wrapping purposes, try to add/remove (depending on status) namCol from the list of columns of interest. The verb "try" is used in the sense that neither attempting to repeat an existing entry nor to remove a non-existent entry will work. .SECTION Thanks Thanks to Philippe Pebay and David Thompson from Sandia National Laboratories for implementing this class.
To create an instance of class vtkUnivariateStatisticsAlgorithm, simply invoke its constructor as follows
obj = vtkUnivariateStatisticsAlgorithm
obj
is an instance of the vtkUnivariateStatisticsAlgorithm class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkUnivariateStatisticsAlgorithm = obj.NewInstance ()
vtkUnivariateStatisticsAlgorithm = obj.SafeDownCast (vtkObject o)
obj.AddColumn (string namCol)
- Convenience method to create a request with a single column name \p namCol in a single
call; this is the preferred method to select columns, ensuring selection consistency
(a single column per request).
Warning: no name checking is performed on \p namCol; it is the user's
responsibility to use valid column names.
int = obj.RequestSelectedColumns ()
- Use the current column status values to produce a new request for statistics
to be produced when RequestData() is called.
Unlike the superclass implementation, this version adds a new request for each selected column
instead of a single request containing all the columns.
