<P>
Provides support for converting longs to Strings, and back again. The strings are structured so that lexicographic sorting order is preserved. <p> That is, if l1 is less than l2 for any two longs l1 and l2, then NumberTools.longToString(l1) is lexicographically less than NumberTools.longToString(l2). (Similarly for "greater than" and "equals".) <p> This class handles <b>all</b> long values (unlike <A HREF="../../../../org/apache/lucene/document/DateField.html" title="class in org.apache.lucene.document"><CODE>DateField</CODE></A>).
