Hi!
I would like to pass arrays of objects to a function taking an array of
parent class as argument.
I try different things but unfortunately I have compilation errors each
time.
The following example works with no array:
class A {
int a;
}
class B extends A {
int b;
}
fun void plus(A arg) {
arg.a ++;
}
B foo;
1 => foo.a;
plus (foo);
<<<"foo.a", foo.a>>>;
But When I try the same with arrays it doesn't compile:
[l13.ck]:line(22): argument type(s) do not match:
[l13.ck]:line(22): ... for function 'plus(...)' ...
[l13.ck]:line(22): ...(please check the argument types)
class A {
int a;
}
class B extends A {
int b;
}
fun void plus(A arg[]) {
for (0 => int i; i < arg.size() ; i++) {
arg[i].a ++;
}
}
B foo[2];
1 => foo[0].a;
2 => foo[1].a;
plus (foo);
<<<"foo[0].a", foo[0].a>>>;
<<<"foo[1].a", foo[1].a>>>;
Any idea ?
Thanks in advance and Happy new year!!
