Vanris Subject: Modification of FlexLexer.h
Date: Thu, 17 Jan 2002 14:35:26 -0600
I modified FlexLexer.h a bit.
To prevent a compiler warning (complaining that yylex() was hiding this function) I added in class yyFlexLexer the following:
int yylex( istream* new_in, ostream* new_out = 0 ) { return FlexLexer::yylex(new_in, new_out); }
Also in the class yyFlexLexer I added a protected method:
Function that can be used by subclasses during yylex() virtual int actionHook(void* data = 0) { return data == 0; }
I override this function in a subclass of yyFlexLexer and I use it in the lex file to call my subclass. Any data I have to save (e.g. character count) I can now keep in my own subclass as memberfields instead of global variables in the lex file.
I attached the FlexLexer.h file.
I don't know whether Flex is still maintained since the last tarfile is from July 27th 1997, but I thought I at least pass it on.
Frank Vanris.
