Usage
(since C++11) |
- In a template declaration,
class
can be used to introduce type template parameters and template template parameters - If a function or a variable exists in scope with the name identical to the name of a class type,
class
can be prepended to the name for disambiguation, resulting in an elaborated type specifier
Example
class Foo; // forward declaration of a class class Bar { // definition of a class public: Bar(int i) : m_i(i) {} private: int m_i; }; template <class T> // template argument void qux() { T t; } int main() { Bar Bar(1); class Bar Bar2(2); // elaborated type }
