 Posted: Thu Aug 17, 2006 9:10 am Post subject: how to put template class into container |
 |
|
i have made a template class like this,
template< typename T>
class CStatus
{
public:
~CStatus(){}
void OnRender(CDisplay * pDisplay)
{
if ( C24Operator::operator_empty != _status)
{
_t->Render(pDisplay);
}
}
C24Operator::status_operator _status;
T _t;
public:
CStatus(C24Operator::status_operator st, T t)
{
_t =t;
_status = st;
}
private:
CStatus( const CStatus&);
CStatus operator=(const CStatus&);
};
Now i want to put its entities into a container ,for example a list
list<CStatus<>> alist is error, how should i do? thanks ahead |

You can't declare a list of 'any CStatus'. You need a concrete type
e.g. CStatus<int>:
std::list<CStatus<int> > alist;

Leave a space. |
std::list<CStatus<> > alist;

Hi,
I have had a similar problem where it was not possible to declare a
std::vector using a std::pair as element type, i.e.
std::vector<std::pair<...>>
I solved this by making a typedef of the pair,
typedef std::pair<...> MyPair;
and then using this in the vector,
std::vector<MyPair>
this solved the problem for me. I hope you get some results from it.
Best regards,
