/**
|
|
* This class splits up text into tokens representing a .ini file.
|
|
* <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>IniTokenMaker.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>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>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.
|
|
* </ul>
