<div class="block">A <i>String_Vector_Comparator</i> implements the Comparator
interface to sort Lists of Objects.
<p>
It is particularly useful, for example, in sorting a set of results
from a Database query. Use an instance of this class as the
Comparator in the Collections.sort(List, Comparator) static method,
which actually does the sorting. The Objects to be compared are
assumed to be Lists. The Objects at the specified index of each
List are converted to Strings. If these Strings can be parsed as
Doubles then these are compared numerically. Otherwise the Strings
are are compared lexicographically.
