how do I provide extra member function for specialized template in a non-inline way? i.e.
template<typename T>
class sets
{
void insert(const int& key, const T& val);
};
template<>
class sets<bool>
{
void insert(const int& key, const bool& val);
void insert(const int& key){ insert(key, true); };
};
But when I write sets<bool>::insert(const int& key)
as
template<>
class sets<bool>
{
void insert(const int& key, const bool& val);
void insert(const int& key);
};
template<>
void sets<bool>::insert(const int& key)
{
insert(key, true);
}
GCC complains:
template-id ‘insert<>’ for ‘void ip_set::insert(const int&)’ does not match any template declaration
