(C++) Host class

 

A Host class is a class that takes a template parameter of a policy. Or: a Host class defines how a group of classes should be generated, as opposed to a class in C++ as being how the group of objects should be generated:

 

---

template <class T> struct MyClass {   T x; }; int main() {   MyClass<int> m;   m.x = 10; }

 

Many STL classes are Host classes.

 

There is no semantic difference between class and typename in a template-parameter [1].
