derived class

derived class

(programming)
(Or "subclass") In object-oriented programming, a class that is derived from a base class by inheritance. The derived class contains all the features of the base class, but may have new features added or redefine existing features.

The synonym "subclass" is possibly confusing since the derived class has a superset of the base class's features.

Compare derived type.

In addition, TBrun automatically handles a number of specific language features for C++ such as access to private and protected data, testing of abstract classes and pure virtual methods, ability to test base class methods with a derived class object, template parameters and member templates, vtable verification, test case inheritance from testing the base class, template specialisation and partial specialisation.
General Bandwidth's G6 Universal Media Gateway Platform provides not only the scalability and capacity to best meet our service growth needs but provides a universal gateway solution that enables simultaneous support for derived Class 5 and next generation softswitch-based services, simplifying the transition of clients to the new architecture.
Normally the implementation is realized by directly inheriting from the abstract class, which does not allow any changes on the inherited structure of the derived class.
In addition, when the matched-model index (chart 4) is compared with the hedonically derived class 1 and 3 indexes, the differences are small.
This is remarkable through the abstract methods Load and Save defined in the base class, methods that any derived class will be obliged to implement.
As European operators begin the migration of their circuit switched network to next generation packet switches, the G6 is designed to provide a simple migration path, enabling service providers to deploy not only derived Class 5 architectures, but with partners IPVerse and TTI, the G6 also enables hybrid Class 5/softswitch implementations and Class 5 replacement architectures.
In this inheritance situation, the class used as the starting point is known as the base class, and the new class is called the derived class.
Deriving a class from another class automatically enables the public (and protected) data members and public (and protected) methods of the base class to be available in the derived class.
Inheritance allows a derived class to redefine behavior specified by a base class.
