Template specialization of function is not as flexible as specialization of struct
: only full specialization is allowed. If you want to do partial specialization you need to wrap your foo
function inside a struct
:
template <typename T> class MyClass { };
template <typename T> struct Foo;
template <typename T> struct Foo { void foo() {}};
template<> struct Foo<int> { void foo() { } };
template<typename T> struct Foo< MyClass<T> > { void foo() {} };
And then instead of calling
foo<MyClass<...>>()
you call
Foo< MyClass<...> >::foo()
