I just tested it again to make absolutely sure.
objects.popBack() returns "... :(void)" and
objects[count-1] returns something of type "object" so it seems like this is
a popback issue more than something that is fundamentally impossible.
Below is a corrected version that does work and IMHO .popBack() can go on
the bug list.
Yours,
Kas.
class Collection {
Object objects[0];
0 => int count;
fun void add( Object obj ) {
objects << obj;
count++;
}
// this you can't do, apparently...
fun Object pop() {
objects[count-1] @=> Object s;
count--;
objects.size( objects.size()-1);
return s;
}
}
Collection myCollection;
SinOsc s;
Gain g;
Event e;
myCollection.add( s );
myCollection.add( g );
myCollection.add( e );
<<< myCollection.count >>>;
myCollection.pop() $ Event @=> Event f;
//make sure we can use it without crashing
f.signal();
<<< myCollection.count >>>;
