public class StringComparator extends Object implements Comparator<String>
This class is primarily used for comparing docnos, especially for TREC like collections. The docnos in the DocumentIndex as expected to be sorted in an order compatible with this comparator.

int |
compare(String s1,
String s2)
Compares two Strings, which have a number of fields that
are separated by one or more non-alphanumeric characters.
|
static int |
compareObjects(Object o1,
Object o2)
A static access method, to prevent having to instantiate a comparator
This has the same parameters, return and implementation as compare(Object,Object)
|
static int |
compareStrings(String s1,
String s2)
A static access method, to prevent having to instantiate a comparator
This has the same parameters, return and implementation as compare(Object,Object)
|
static void |
main(String[] args)
Will display the comparator value between two strings from the command line arguments.
