= Multiple Inheritance with template 'bolt-ins' =

''Part of'' TemplatesCategory


== Description ==

I've been experimenting a little, most of this is taken from Andy Freisens streams.d which doesn't appear to be on the web anymore. His is a very good example, this is trivial please expand on it!


== Example ==

{{{
#!d
import std.c.stdio;

interface Vehicle {    
    void drive();
    void stop();
}

class Car (T) : T , Vehicle{
    void drive() { puts("driving on land");} 
    void stop () { puts("stopping on land"); } 
    
    void driveOnRoad() { puts("driving on road"); }
}

class Boat (T) : T , Vehicle {     
    void drive () { puts("driving on water"); } 
    void stop () { puts("stopping on water"); } 
    
    void floatOnWater() { puts("floating on water"); }     
}


alias Car!( Boat!(Object ) ) CarBoat;
alias Boat!( Car!(Object ) ) BoatCar;    

void main ( ) {    
    CarBoat x = new CarBoat;
    x.floatOnWater();
    x.driveOnRoad();
    x.drive();
    
    puts("\n");
    
    BoatCar y = new BoatCar;
    y.floatOnWater();
    y.driveOnRoad();
    y.drive();    
}
}}}
