template

[Kohinoor24]

I have a template class as follows:
I would like to make it a singelton class;
I did some thing as follows:,But It is showing me errors...

template<class _base>
class Writer:public _base

{
public:

}

static Writer<_base>* Instance();

};

template<class _base>
Writer<_base>* Writer<_base>::Instance()
{
static WriterThread<_base> theWriter();
return &theWriter;
}

Is it right?

Thanks in advance

At first glance.


template<class _base>
class Writer : public _base
{
public:

} // syntax error
static Writer<_base>* Instance();
};

template<class _base>
Writer<_base>* Writer<_base>::Instance()
{
static WriterThread<_base> // WriterThread should be Writer
theWriter(); // function declaration, not constructor
return &theWriter;
}

No compile errors with some changes:


template<class _base>
class Writer : public _base
{
public:
static Writer<_base>* Instance()
{
return theWriter;
}

private:
static Writer<_base>* theWriter;
};



Is this what you're looking for?

Please don't post the same message on multiple forums. It's very annoying. I really hate to see something I answered already answered on another forum. I feel you've just wasted my time.

At the very least, if you just can't resist, you should wait a bit before posting to the other forum.
