[Exceptions] Custom type in error_info value?
by Andrew Chinkoff 01 Mar '10

01 Mar '10

This is the test program I would like to be explained to me: #include <iostream> #include <string> #include <boost/exception.hpp> struct MyException: virtual boost::exception{ }; class MyClass { char* s; public: MyClass(const char* msg) : s(strdup(msg)){ } MyClass(const MyClass& c){ s = strdup(c.s); } ~MyClass(){ free(s); } }; void main() { MyException ex; ex << boost::error_info<struct my_tag1, MyClass>("qweqwe"); ex << boost::error_info<struct my_tag2, std::string>("asdasd"); std::cout << boost::diagnostic_information(ex); } This is the program output: > Throw in function (unknown) > Dynamic exception type: struct MyException > [PAUmy_tag1@?1?main@] = [ type: ?AV?$error_info@Umy_tag1@?1?main@VMyClass @@@boo > t@@, size: 8, dump: 50 69 10 01 b8 18 7f 00 ] > [PAUmy_tag2@?1?main@] = asdasd So, my question: what should I do with 'MyClass' to see the output like this: > Throw in function (unknown) > Dynamic exception type: struct MyException > [PAUmy_tag2@?1?main@] = qweqwe (Wow !!! Terrible dump is replaced with readable string here !!!???) > [PAUmy_tag2@?1?main@] = asdasd Thanks, Andrew.

I am looking into boost test. I dont not want to expose some member functions as public. However I need to access them for testing, is there any way making boost test a friend of this class ? Any help appreciated. Best regards, Ta, Avi
