[Dev-C++] typedef problem

[Marcos C. C. <ca...@in...>]

Hello!

I have a problem with a c++ library that I'm developing.I have one class to
define a generic container and another class to a generic iterator, like this:

template <class T> class GenericIterator{
    .....
};

template <class T> class GenericContainer{
      ....
      typedef GenericIterator<T>  BasicIterator;
      ....
};

When this code is compiled, there was several warnings messages in the typedef
inside of container class and in that locals where I use BasicIterator. The
warnings are like "implicit typename is deprecated, see documentation". 

However, I need this type definition to allow a iterator declaration through the
container class, like:

int main()
{
    Container<int> c;
    Container<int>::BasicIterator i;
    ....
}

How can I do to make this without error and/or warnings messages?

Thanks,

Marcos

Just type this:

typedef template class GenericIterator<T>  BasicIterator;

That should work.

Cheers,
Stefan

Correction - Was: [Dev-C++] typedef problem

[stefan k. <ste...@ya...>]

Never answer from pure memory... ;-)

The correct syntax (verified in .NET) is:

typedef class GenericIterator<T>  BasicIterator;

Best,
Stefan
