sortCol -

naturalOrder -

Method Detail

addCompareCol

public void addCompareCol(int sortCol)

Compare the passed in col in natural order

addCompareCol

public void addCompareCol(int sortCol,
                          boolean naturalOrder)

Compare the passed in col in natural or reverse order

addCompareCol

public void addCompareCol(int sortCol,
                          java.util.Comparator comparator)

Compare the passed in col based on the passed in Comparator

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)

Method used by the comparator interface.

o1 < o2 - returns a negative integer
o1==o2 - returns zero
o1>o2 - returns a postitive integer

Iterate through all columns that should be compared (in the proper order) and call the Comparator for each of the column elements.
