how to non-default construct with multiple virtual inheritance??
Hello, how to write a non-default constructor for a class that inherits an indirect base class, with multiple intermediate classes that list the base as virtual? In the SSCCE below, the compiler complains "error: no matching function for call to ´┐ŻBase::Base()". Thank you, Mark class Base { public: Bas... 4 Jun 2010 10:18
Container adapter to treat a sorted vector as a set
Hi, I'd like to be able to use a sorted vector as a set (or map) with a parametrized (template) function that expects a set (or map) interface. The function only calls find, not insert or erase. I thought that this could be accomplished using a container adapter. Does this seem like a good approach? Cheers, ... 8 Jun 2010 05:49
Throwing error is potentially buggy
>From a different site, a programmer asked for proper coding standard (error handling) for a common program scenario: initialize(); while (true) { Message msg,out; receive(msg); process(msg,out); send(out); } I thought it would be very difficult to throw std::exception classes to handle al... 8 Jun 2010 13:41

Names or traits for std::random param_type access methods?
Are there trait definitions and common names for the param_type access methods of std::random (i.e., #include <random>)? The distribution- specific names are sensible, but is there introspection support? Each distribution template defines a struct param_type { ... }, as well as access methods. Access methods ar... 2 Jun 2010 09:48
Temporaries passed to constructor yield invalid member references
> The difference is that you can pass a temporary as a const-ref without seeing it, while you cannot pass a temporary as a pointer without some syntactic overhead. (This statement does *only* apply to the immediate call - it does not apply to general lifetime management.) But lifetime management is a very i... 2 Jun 2010 09:48
Temporaries passed to constructor yield invalid member references
Razvan Cojocaru wrote: Use a const pointer. Use it for the argument passing and if it's not too much hassle also use it for the member. Bottom line for me is: Always use pointers for these parameters. Use a pointer member in "90%" of cases. I don't see the difference between his problem using... 1 Jun 2010 13:04
