|
---|
| 19 | * A parser for the C++ programming language.
|
---|
| 20 | *
|
---|
| 21 | * This implementation was created using
|
---|
| 22 | * <a href="http://www.jflex.de/">JFlex</a> 1.4.1; however, the generated file
|
---|
| 23 | * was modified for performance. Memory allocation needs to be almost
|
---|
| 24 | * completely removed to be competitive with the handwritten lexers (subclasses
|
---|
| 25 | * of <code>AbstractTokenMaker</code>, so this class has been modified so that
|
---|
| 26 | * Strings are never allocated (via yytext()), and the scanner never has to
|
---|
| 27 | * worry about refilling its buffer (needlessly copying chars around).
|
---|
| 28 | * We can achieve this because RText always scans exactly 1 line of tokens at a
|
---|
| 29 | * time, and hands the scanner this line as an array of characters (a Segment
|
---|
| 30 | * really). Since tokens contain pointers to char arrays instead of Strings
|
---|
| 31 | * holding their contents, there is no need for allocating new memory for
|
---|
| 32 | * Strings.<p>
|
---|
| 33 | *
|
---|
| 34 | * The actual algorithm generated for scanning has, of course, not been
|
---|
| 35 | * modified.<p>
|
---|
| 36 | *
|
---|
| 37 | * If you wish to regenerate this file yourself, keep in mind the following:
|
---|
| 38 | * <ul>
|
---|
| 39 | * <li>The generated CPlusPlusTokenMaker.java</code> file will contain two
|
---|
| 40 | * definitions of both <code>zzRefill</code> and <code>yyreset</code>.
|
---|
| 41 | * You should hand-delete the second of each definition (the ones
|
---|
| 42 | * generated by the lexer), as these generated methods modify the input
|
---|
| 43 | * buffer, which we'll never have to do.</li>
|
---|
| 44 | * <li>You should also change the declaration/definition of zzBuffer to NOT
|
---|
| 45 | * be initialized. This is a needless memory allocation for us since we
|
---|
| 46 | * will be pointing the array somewhere else anyway.</li>
|
---|
| 47 | * <li>You should NOT call <code>yylex()</code> on the generated scanner
|
---|
| 48 | * directly; rather, you should use <code>getTokenList</code> as you would
|
---|
| 49 | * with any other <code>TokenMaker</code> instance.</li>
|
---|
| 50 | * </ul>
