In this article, I describe a static (that is, compile time) assert facility that supplements the classic assert and give examples on when and how to use it.Ralf HollyC - C++ Users JournalKevin S. Van Horn. Compile-time assertions in C++. C/C++ Users Journal, October 1997. URL http:...
现实中的应用——BOOST_STATIC_ASSERT & boost::checked_delete BOOST_STATIC_ASSERT 在boost/static_assert.hpp中定义了一个宏BOOST_STATIC_ASSERT,用于完成编译时静态检查。其实现方式了我们的第2种方式很类似,利用了模板的特化技术 #defineBOOST_STATIC_ASSERT( B ) \ typedef::boost::static_assert_test<\ siz...
此时,就可以利用Compile-time Assertion解决这个问题。 template<typename To, typename From> To safe_reinterpret_cast(From from) { assert(sizeof(To) >= sizeof(From)); return reinterrupt_cast (from); }; 而后,就像你使用同样的C++ 类型转换一样来使用这个safe_reinterpret_cast : longl = 255; short...
the compiler is able to check assertions at compile time. This is a big advantage, as assertions checked at compile time do not consume any code and do not affect performance. In this article, I describe a static (that is, compile time) assert facility that supplements the classic assert ...

我希望在compile-time中发现这个错误,这样我就可以避免在更新枚举时引入runtime-error。C++中有没有办法在compile-time处强制执行color_names的initializer-strings的数目必须等于数组的长度(即max_item)? max_itemstatic_assert 本站已为你智能检索到如下内容,以供参考: ...
