where does it say non-modifying operations can't throw?
in [C++]
|
From: catphive on 20 Apr 2010 15:47 Josuttis' book has a nice table showing exception safety guarantees for container operations on page 249; however, it only talks about modifying operations. It's common sense that non-modifying operations like size() and empty() should have a no-throw guarantee, but I didn't notice anything about it in Josuttis' book or the standard. Is this specified somewhere I'm missing? Is it acceptable for non-modifying operations like size() to throw for some standard containers? It would be nice if there were a table of all standard functions with their exception spec somewhere...

No. There was a proposal by Rani Sharoni titled 'Improving the standard library�s exception specifications' http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2009/n2815.html -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.
