Behavior of array deletion if an element's dtor throws

ideas for data binding?
I want to serialize some objects and modify it with a GUI. An example: class Library { private: string m_city; vector<Book*> m_books; }; class Book { private: string m_title; int m_count; }; My first approach was something straigtforward, which kind of works, but is a maintenance and code-... 4 May 2010 03:31
What's the proper way of initializing a std::function?
Hi, In C++0x, is lambda the most proper way to initialize a std::function with a valid function that does nothing? class SomeClass { public: SomeClass() : fnc_([]{}) {} private: std::function<void()> fnc_; }; Thanks, Daniel -- [ See for info... 23 May 2010 14:38
[ANN] CodeSynthesis XSD 3.3.0 released
Hi, I am pleased to announce the availability of CodeSynthesis XSD 3.3.0. CodeSynthesis XSD is an open-source (GPL2 + proprietary license), cross- platform W3C XML Schema to C++ data binding compiler. Provided with a schema, it generates C++ classes that represent the given vocabulary as well as parsing and se... 28 Apr 2010 15:08
cv qualified return types
Hi, I would like to know what should be the behavior of the compiler for the code shown const int fn(){return 0;} Comeau/Gcc give warning whereas C++ standard does not appear to mention anything specific. However looking at the grammar, it appears to me that such a declaration is syntactically legal. R... 28 Apr 2010 02:51
friend function and storage specifier
class Sample{ static friend void afriend(){} }; int main(){} My query: 1. why is storage specifier not allowed in friend function declaration? 2. Which part of the standard actually mentions about this restriction? Regards, Dabs -- [ See for info a... 30 Apr 2010 09:28
Static const size_t member initialization
I'm running into a problem with my C++ compiler. I don't know whether what I am doing is illegal, or it's a compiler bug. My understanding is that you can initialize a static const integer in the class declaration. But my compiler (Sun studio11) doesn't allow it for size_t, which I always assumed was an integer... 28 Apr 2010 02:51
C++0x support in compilers for embedded systems

move only types in standard containers
I'm trying to use a type that is moveable, but not copyable, in a standard container, in this case an unordered_map. When I try to insert it, I get complaints about a deleted copy constructor. I thought that move only objects were supported in standard containers? Here's my type: struct session_t { sessi... 30 Apr 2010 06:11
