Overriding a function in an extended class, with different arguments.

in Programming Questions • 11 months ago

Hi, i get an error when trying to override a function in an extended class, i wonder if someone can help me with this. Basically, what i want to do is to override a function but calling it with different arguments:

void setup() {
Thing thing = new anotherThing();
thing.function(); // this works, but calls the function in the main class.
//thing.function(new PVector()); // this doesn't work
}
class Thing {
Thing() {
//some code
}
void function() {
// This function has no arguments
println("this is Thing's function, with no arguments");
}
}
class anotherThing extends Thing {
anotherThing() {
super();
//some extra code
}
void function(PVector aVector) {
println("this is AnotherThing's function, called with an argument " + aVector);
}
}

Is there a way to do this?

Thanks for any help!

Since it has different arguments, you don't need to override, you can just use function overloading. The classes you have are already fine. But of course ONLY the anotherThing class has the method that takes a PVector. So if you want to call this method, it has to be an object of type anotherThing:

anotherThing thing = new anotherThing();
thing.function(new PVector());

Thanks amnon! it works! I'm actually using it for making a network visualizing sketch using your tutorial on augmented reality... I will post it somewhere once i finish it, hopefully...
