Hello,
ok, if I got your problem, you ran into the problem, that you can't pass
arguments to the template class, because the template class itself is a
argument.
You have to write a method wich forks the additional parameters like
this:
myNodeClass<tClass> sometpl;
sometpl.push_back("parameter"); // where parameter is type string
So the constructor of tClass don't have parameters.
Just have a look at
http://www.cppreference.com/wiki/stl/vector/vector_constructors
There you can define wich type of template the vector should contain,
but the template data is later.
If I have missunderstood your problem, or I'm generally wrong, just
correct Me. :-)
Greetings
Bernd
