template<typename T> NamedObject<typename T>::NamedObject(const char *name, const T& value)的定义格式在vs中可以顺利编过, 但是在gcc中会报 error: template argument 1 is invalid的错误,应该定义成 去掉第二个typename template<typename T> NamedObject<T>::NamedObject(const char *name, const T& valu...

如果所有template argument都可以推导得出,你就无需在function template名称后面加写角括号。 1. 函数式模板自变量Function Template Argument 既可以指定function template 的 template argument,也可以让它们被编译器推导出来。例如, template <typename T> inline T const& max(T const& a, T const & b) { return...
If an argument can be interpreted as both a type-id and an expression, it is always interpreted as a type-id, even if the corresponding template parameter is non-type: template<class T> void f(); // #1 template<int I> void f(); // #2 void g() { f<int()>(); // "int()...

If more than one DjangoTemplates engine is defined, the first one will be used. class Template[source]¶ This class lives at django.template.Template. The constructor takes one argument — the raw template code: from django.template import Template template = Template("My name is {{ my_...
Template argument deduction is also performed when the name of a class template is used as the type of an object being constructed: std::pair p(2, 4.5); std::tuple t(4, 3, 2.5); std::copy_n(vi1, 3, std::back_insert_iterator(vi2)); std::for_each(vi.begin(), vi.end(),...
ADL( Argument-Dependent Lookup)查找为依赖于参数的查找,是用于函数调用表达式中查找非限定函数名称的规则。当在使用函数的上下文中找不到函数定义,我们可以在其参数的关联类和关联名字空间中查找该函数的定义。 ADL 生效条件:a.使用此规则的函数必须要有参数 b. 使用此规则的函数名称必须为非受限名称 4.ADL 查找范...
