public String map(String canon)

Description copied from interface: TextMapper

Maps arg to another String and returns it.

Specified by:

Parameters:

canon - the String to be mapped

unmatch - the String to be returned if the argument does not match any mapping.

Returns:

the String in the "Range Set" resulting from the map, or unmatch if arg was not contained in the Domain Set, and the mapper therefore did not know how to map.
