/**
* Scanner for the Tcl programming language.
*
*
* This implementation was created using
* JFlex 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
* AbstractTokenMaker, 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.
*
*
* The actual algorithm generated for scanning has, of course, not been
* modified.
*
*
* If you wish to regenerate this file yourself, keep in mind the following:
*
* - The generated
TclTokenMaker.java file will contain two
* definitions of both zzRefill and yyreset. 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.
* - 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.
* - You should NOT call
yylex() on the generated scanner
* directly; rather, you should use getTokenList as you would with
* any other TokenMaker instance.
