    The global access modifier declares that this class is known by all Apex code everywhere. ... The virtual definition modifier declares that this class allows extension and overrides. You cannot override a method with the override keyword unless the class has been defined as virtual .

    In object-oriented programming, a virtual class is a nested inner class whose functions and member variables can be overridden and redefined by subclasses of an outer class. Virtual classes are analogous to virtual functions.
