You have mis-read or mis-understood (or you need better books). Consider: virtual_vector<person>* p = new people; delete p; That invokes undefined behaviour unless virtual_vector<person> has a virtual destructor. In *practise*, you will (probably) get away with it. The most *likely* behaviour is that virtual_vector<>::~virtual_vector() will be called, without calling people::~people(). ... but that doesn't alter the fact that it *is* undefined behaviour, which is not good. -- Martin Bonner Martin.Bonner(a)Pitechnology.com Pi Technology, Milton Hall, Ely Road, Milton, Cambridge, CB4 6WZ, ENGLAND Tel: +44 (0)1223 441434

Is there any interest in a library that provides containers with virtual destructors?
by Andy Tompkins 26 Oct '05

26 Oct '05

I have read a few times that people sometimes wish that std::vector (or other containers) had a virtual destructor. I have recently wished for the same thing and I fairly quickly write a class called virtual_vector something like: template <class Type, class Allo = std::allocator<Type> > class virtual_vector { public: ~virtual_vector(); ... private: std::vector<Type, Alloc> m_vector; }; All the public methods of std::vector are present in virtual_vector and are just forwarded on m_vector. This allows one to write something like: struct person { string first_name; string last_name; }; class people : public virtual_vector<person> { public: //extra methods }; Is this useful? Has this been done already? Thanks in advance for any comments? Andy Tompkins

[Xpressive] How to quantify embedded regex?
by BRIDGES Dick 24 Oct '05

24 Oct '05

I am trying to use Xpressive for parsing string-based message buffers. The messages start with a fixed string and end with an "empty" line (similar in form to HTTP). Here is code that illustrates my problem: int main(int argc, char **argv) { std::string buffer_ = "FROGGIE\r\n" "Volume = 3\r\n" "Other1= 0\r\n" "Channel=1\r\n" "Other =2\r\n" "\r\n" "FROGGIE\r\n" "Volume = 4\r\n" "Other1= 8\r\n" "Channel=5\r\n" "Other =3\r\n" "\r\n" "FROGGIE\r\n" "Volume = 4\r\n" "Other1= 8\r\n" "Channel=5\r\n"; // mark_tag name_(1), value_(2); To be used in the name_value_pair later. sregex name_value_pair_ = +alnum >> *_s >> "=" >> *_s >> +_d >> *_s >> _ln; sregex re_ = "FROGGIE" >> _ln >> name_value_pair_ >> _ln; // sregex re_ = "FROGGIE" >> _ln >> repeat<1,5>(name_value_pair_) >> _ln; // sregex re_ = "FROGGIE" >> _ln >> +(name_value_pair_) >> _ln; } The only examples of repeating an embedded regex I could find in the .pdf or the examples subdirectory used predefined regexes like alnum but still, it looked to me that the lines that are commented out should have worked. I am clearly wrong. Both of these forms create very long error messages that end with "internal compiler error". One of those error messages is included as an attachment. The uncommented line compiles fine. Since I'm not very accomplished at regular expressions, maybe I should point out that, besides being able to extract the name/value pairs from each message in turn, I want to use what.suffix() to identify the partial message at the end of the buffer. OS is Linux Core 3 2.6.9-1.667. Compiler is gcc 3.4.2 20041017 (Red Hat 3.4.2-6fc5). Xpressive README (in the .zip) says "Last Modified: October 9, 2005". If someone could point me in the right direction, I'd surely appreciate it. If this query is not appropriate for this group, should I post it to boost-users(a)lists.boost.org or mail the author directly or..? Regards, Dick Bridges
