Is there a list of STL container methods that may throw an exception anywhere?
I know the STL will throw on a memory allocation error or if the contained type throws in its constructor / assignment operator.
Otherwise, apparently 'a few' STL methods can throw other exceptions. The example everyone seems to mention is vector::at(), but I can't find a list of the others anywhere.
Does anyone know of such a list? 开发者_开发问答
Won't be 100% accurate, and is for C++03, but a half-hour effort based on grepping through GCC 4.3.4 includes, ignoring tr1 and ext but including iostream. Crucially, some of these checks might be due to this implementation prefering more defensive coding, and might not be mandated in the Standard and available universally....
bitset
std::overflow_error

Well, I have this big, gigantic book titled, The C++ Standard, that contains a complete description of all functions in the standard library and what they can/cannot do.
