Method Detail

getInstance

public static DataValueComparator getInstance()
Returns:
the only living instance

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
