/**
* Scanner for Ruby.
*
* 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
RubyTokenMaker.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.
