Memory allocation needs to be almost * completely removed to be competitive with the handwritten lexers (subclasses * of <code>AbstractTokenMaker</code>, so this class has been modified so that * Strings are never allocated (via yytext()), and the scanner never has to * worry about refilling its buffer (needlessly copying chars around). * We can achieve this because RText always scans exactly 1 line of tokens at a * time, and hands the scanner this line as an array of characters (a Segment * really). Since tokens contain pointers to char arrays instead of Strings * holding their contents, there is no need for allocating new memory for * Strings.<p> * * The actual algorithm generated for scanning has, of course, not been * modified.<p> * * If you wish to regenerate this file yourself, keep in mind the following: * <ul> * <li>The generated <code>XMLTokenMaker.java</code> file will contain two * definitions of both <code>zzRefill</code> and <code>yyreset</code>. * You should hand-delete the second of each definition (the ones * generated by the lexer), as these generated methods modify the input * buffer, which we'll never have to do.</li> * <li>You should also change the declaration/definition of zzBuffer to NOT * be initialized. This is a needless memory allocation for us since we * will be pointing the array somewhere else anyway.</li> * <li>You should NOT call <code>yylex()</code> on the generated scanner * directly; rather, you should use <code>getTokenList</code> as you would * with any other <code>TokenMaker</code> instance.</li> * </ul> * * @author Robert Futrell * @version 1.0 */ public class DtdTokenMaker extends AbstractJFlexTokenMaker { /** This character denotes the end of file */ public static final int YYEOF = -1;
