Arrays class and web-export

in Processing with Other Languages • 11 months ago

Hi, I'm using processing to implement an algorithm for computing convex hulls. I'm using the class Arrays to sort an array of type Point (a class I created). This work fine with java but as I try to use it with javascript (for web-export), it doesn't work.

Here is my code:

List<Point> points;
...
void mousePressed() {
...
Point[] arrpoints = new Point[points.size()];
points.toArray(arrpoints);
Comp c = new Comp();
println("work until here");
Arrays.sort(arrpoints,c);
println("Never get here");
...
}
...

I guess I can't use the Arrays class if I want to web-export ? Any idea ?

Thank you!

ps : Entire code is available here :

No, you can't use most Java classes, except perhaps ArrayList and HashMap which are, to my knowledge, ported to JavaScript. I don't know what else is supported, if any.
Note: Processing has a sort() function... But not with a comparator. Perhaps you can do the sort in pure JavaScript, I am not sure how JS and Processing code can be mixed.
