20 * Scanner for the Scala programming language.<p>
21 *
22 * This implementation was created using
23 * <a href="http://www.jflex.de/">JFlex</a> 1.4.1; however, the generated file
24 * was modified for performance. Memory allocation needs to be almost
25 * completely removed to be competitive with the handwritten lexers (subclasses
26 * of <code>AbstractTokenMaker</code>, so this class has been modified so that
27 * Strings are never allocated (via yytext()), and the scanner never has to
28 * worry about refilling its buffer (needlessly copying chars around).
29 * We can achieve this because RText always scans exactly 1 line of tokens at a
30 * time, and hands the scanner this line as an array of characters (a Segment
31 * really). Since tokens contain pointers to char arrays instead of Strings
32 * holding their contents, there is no need for allocating new memory for
33 * Strings.<p>
34 *
35 * The actual algorithm generated for scanning has, of course, not been
36 * modified.<p>
37 *
38 * If you wish to regenerate this file yourself, keep in mind the following:
39 * <ul>
40 * <li>The generated ScalaTokenMaker.java</code> file will contain two
41 * definitions of both <code>zzRefill</code> and <code>yyreset</code>.
42 * You should hand-delete the second of each definition (the ones
43 * generated by the lexer), as these generated methods modify the input
44 * buffer, which we'll never have to do.</li>
45 * <li>You should also change the declaration/definition of zzBuffer to NOT
46 * be initialized. This is a needless memory allocation for us since we
47 * will be pointing the array somewhere else anyway.</li>
48 * <li>You should NOT call <code>yylex()</code> on the generated scanner
49 * directly; rather, you should use <code>getTokenList</code> as you would
50 * with any other <code>TokenMaker</code> instance.</li>
51 * </ul>
