// BOOST_[APPEND_]EXPLICIT_TEMPLATE_[NON_]TYPE macros --------------------------//
|
|
//
|
|
// Some compilers have problems with function templates whose template
|
|
// parameters don't appear in the function parameter list (basically
|
|
// they just link one instantiation of the template in the final
|
|
// executable). These macros provide a uniform way to cope with the
|
|
// problem with no effects on the calling syntax.
|
|
|
|
// Example:
|
|
//
|
|
// #include <iostream>
|
|
// #include <ostream>
|
|
// #include <typeinfo>
|
|
//
|
|
// template <int n>
|
|
// void f() { std::cout << n << ' '; }
|
|
//
|
|
// template <typename T>
|
|
// void g() { std::cout << typeid(T).name() << ' '; }
|
|
//
|
|
// int main() {
|
|
// f<1>();
|
|
// f<2>();
|
|
//
|
|
// g<int>();
|
|
// g<double>();
|
|
// }
|
|
//
|
|
// With VC++ 6.0 the output is:
|
|
//
|
|
// 2 2 double double
|
|
//
|
|
// To fix it, write
|
|
//
|
|
// template <int n>
|
|
// void f(BOOST_EXPLICIT_TEMPLATE_NON_TYPE(int, n)) { ... }
|
|
//
|
|
// template <typename T>
|

// void g(BOOST_EXPLICIT_TEMPLATE_TYPE(T)) { ... }
