This file defines FlexLexer, an abstract class which specifies the external interface provided to flex C++ lexer objects, and yyFlexLexer, which defines a particular lexer class.

If you want to create multiple lexer classes, you use the -P flag to rename each yyFlexLexer to some other xxFlexLexer. You then include <FlexLexer.h> in your other sources once per lexer class:

#undef yyFlexLexer #define yyFlexLexer xxFlexLexer #include <FlexLexer.h>

#undef yyFlexLexer #define yyFlexLexer zzFlexLexer #include <FlexLexer.h> ...Never included before - need to define base class.

#define yyFlexLexerOnce

Either this is the first time through (yyFlexLexerOnce not defined), or this is a repeated include to define a different flavor of yyFlexLexer, as discussed in the flex manual.
