class application: protected manager <application>
{
friend class manager<application>
I'm new to C++, but have to understand this from an foreign source-code, which meets my requirements.
What I know up to know: The class application is derived from the class manager by the ":". "application" in angel brackets means, that the class manager is a template class and application is the template parameter.
But what are the consequences of taking the derived class as template parameter for the base class? I don't understand this.
Can someone explain please?
