For example:
template<unsigned number>
struct A
{
template<class T>
static void Fun()
{}
};
And want to specialize A<1>::Fun()
template<>
A<1>::Fun<int>()
{
/* some code here. */
}
doesn't work. How to do it? Thanks.
First of all, you forgot to specify the return type of the function ( void
). Secondly, you need to have two template<>
: one because you are explicitly specializing the class template, and one because you are explicitly specializing its member function template.
Therefore, this is the correct syntax:
template<> // Because you are explicitly specializing the A class template
template<> // Because you are explicitly specializing the `Fun()` member template
void A<1>::Fun<int>()
{
/* some code here. */
}
