Method Detail

compareDataValues

protected int compareDataValues(DataValue v1,
                                DataValue v2)

Do not call this function, rather call the DataValueComparator.compare(DataCell, DataCell) method, which handles missing cells. The derived class should compare the two passed DataValues. It can be safely assumed that both values are castable to the specific type of the DataValue that returned this comparator.

Specified by:

compareDataValues in class DataValueComparator

Parameters:

v1 - the first DataValue to compare the other with

v2 - the other DataValue to compare the first with

Returns:

return -1 if v1 is smaller than v2, +1 if v1 is larger than v2, 0 otherwise
