Class SortOrder

java.lang.Object
uk.ac.starlink.topcat.SortOrder

public class SortOrder extends Object
Defines a sorting order for a table. An instance of this class defines the algorithm by which a sort is done, not rather than a given row sequence.

Currently, the sort order is defined only by the column that the table is sorted on, but this may get extended one day. Note that the sense (up or down) of the sort is selected separately than by this object.
