Perhaps it doesn't provide them because reverse_iterator won't work. At Sunday 2004-05-30 07:40, you wrote:

I've also tried rbegin/rend. However, the boost::tokenizer doesn't provide these methods, while it does provide begin/end.

perhaps you should try rbegin() and rend() like you're supposed to w/ reverse_iterators At Sunday 2004-05-30 04:56, you wrote:

In experimenting with boost::tokenizer to meet a requirement that I have, I've tried hooking it to a reverse iterator. This act produced a run-time error.

This is the code: const string test = "One:Two:Three:Four"; typedef char_separator<char> Sep; typedef tokenizer Tok; Sep sep(":"); Tok t(test,sep); for (Tok::iterator iter=t.end();iter!=t.begin();++iter) cout << *iter << endl;

Executing this produces continous output of "garbage".

Switching the ".end()" and ".begin()" references in the for loop doesn't fix this problem. Switching from "const_reverse_iterator" to "const_iterator" produces the following output: One Two Three Four

Is there a way to use a reverse iterator with boost:tokenizer? _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users

Thanks for this. However, I've figured out that "adopting" a string's reverse iterator isn't the same as having one. I wanted the tokens to be reversed, not the string.... Victor A. Wagner Jr. wrote:
