Method Detail

compare

public int compare(java.lang.reflect.Field fldFirst,
                   java.lang.reflect.Field fldSecond)

Deprecated.

The algorithm in this method prefers to sort a column with an explicit index definition before any column with no index definition. For any pair of columns that have the same defined index, or where neither column has a defined index, the algorithm will sort columns alphabetically by name instead. The only way to have this method return 0 (equal) would be to have two columns with the same name, which is a violation of SQL table requirements anyway.

Specified by:

compare in interface java.util.Comparator<java.lang.reflect.Field>

Parameters:

fldFirst - the first column to be compared

fldSecond - the second column to be compared

Returns:

-1 if the first column should be before the second; 1 if the first column should be after the second; 0 if no sort criteria can be resolved.
