Hello,
I've got a rudimentary CFC question. Can you create class interfaces using
CFCs? I suppose I'm looking for something akin to pure virtual methods in
C. Here's an example of what I'm wanting to accomplish. I know this is
incredibly contrived and the code is a hodgepodge of several different
languages...I'm just trying to get an idea across. Thanks for your input!
Let's say I have a class:
class Vehicle {
real forwardSpeed = 0; // MPH
int numWheels = 0;
char vehicleName = '';
// public methods
real Vehicle::go( real timeInHours ) { return forwardSpeed * timeInHours;
}
void Vehicle::setName( char name ) { vehicleName = name; }
char Vehicle::getName() { return vehicleName; }
// interface methods
void Vehicle::setForwardSpeed( int speed ) = 0;
void Vehicle::setNumWheels( int wheels ) = 0;
}
class Car extends Vehicle {
Car::Car() { super.setNumWheels(4); }
}
Now, in the code I want to create an instance of Car and Motorcycle.
obj1 = CreateObject( "component", "car" );
obj1.setForwardSpeed(50);
obj1.setName("Pinto");
obj2 = CreateObject( "component", "car" );
obj2.setForwardSpeed(120);
obj2.setName("Porsche");
if obj1.go(0.5) > obj2.go(0.5) {
write( obj1.getName() );
else
write( obj2.getName() );
write( " is the winner!" );
