As a convention in this book, class members are summarized by informal class declarations that describe the class as it seems to clients, not how it is actually implemented. For example, here is an informal declaration of class Foo:
class Foo {
public:
int x( );
int y;
~Foo( );
};The actual implementation might look like this:
class FooBase {
protected:
int x( );
};
class Foo: protected FooBase {
private:
int internal_stuff;
public:
using FooBase::x;
int y;
};The example shows two cases where the actual implementation departs from the informal declaration:
Method x() is inherited from a protected base class.
The destructor is an implicitly generated method.
The informal declarations are intended to show you how to use the class without the distraction of irrelevant clutter particular to the implementation.
