template in a template specialization

[manustone]

HI all
I am having trouble in specializing the class below

template< class TPA >
public TClass{

           template< class TPB >
           struct Functor {
               void Foo(){
                        // do someting
               }
            };
};

I would like tomake specialization for Functor< TPB >.
How to do that? I am trying the code blow but it doesn' work

// specialization for Functor inside generic TClass< TPA >
template< class TPA >
void TClass< TPA >::Functor< int >::Foo(){
    // do something else
}

Thanks
Mn

template<typename TPA> template<>
void TClass<TPA>::Functor<int>::Foo()
{
// My code
}

Hi,

I realized that I wrote not the correct code

template< class TPA >
public TClass{
           template< class TPB >
           struct Functor {
               void Foo( TPA obj_1 , TPB obj_2 ){
                        // do someting wotj obj1 and obj2
               }
            };
};

/// specialization for Functor inside generic TClass< TPA >
template< class TPA >
void TClass< TPA >::Functor< int >::Foo( TPA, int ){
    // do something else
}

I tried and I have this
error: invalid explicit specialization before ‘>’ token
error: enclosing class templates are not explicitly specialized
error: no member function ‘operator()’ declared in ‘TClasst<_MyClass>::Mutator< int>::Foo()’

Probably the simplest way would be not to use nested classes.

Thanks man!
