/**
|
||||
* Scanner for the ActionScript.<p>
|
||||
*
|
||||
* This implementation was created using
|
||||
* <a href="http://www.jflex.de/">JFlex</a> 1.4.1; however, the generated file
|
||||
* was modified for performance. 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>ActionScriptTokenMaker.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>
