Iteration

ShockScript features full object-oriented iteration.

iterator.length()
iterator.some(function(v) v > 0)
iterator.(* > 0) // filter

The user may override the key and value iterators by implementing the Iterable.<K, V> interface.

class A implements Iterable.<String, Number> {
    /**
     * Iterate keys.
     */
    public function keys():Iterator.<String> {
        for (var i = 0; i < 10; i++) {
            yield i.toString();
        }
    }

    /**
     * Iterate values.
     */
    public function values():Iterator.<Number> {
        for (var i = 0; i < 10; i++) {
            yield i;
        }
    }
}
