Interface Inheritance
Explore how to define and use interfaces in D programming. Understand the rules for interface inheritance, implementing abstract methods, and combining multiple interfaces for advanced class design. Learn how interface polymorphism enhances flexibility and code reuse in your applications.
Interfaces
The interface keyword is for defining interfaces in class hierarchies. interface is very similar to class with the following restrictions:
-
The member functions that it declares (but not implements) are abstract even without the
abstractkeyword. -
The member functions that it implements must be
staticorfinal. (staticandfinalmember functions are explained later in this chapter.) -
Its member variables must be
static. -
Interfaces can ...
