Arg looping unknow

in Processing Forum one there is a weird code who work very fine, but I don't understand : https://forum.processing.org/one/topic/start-stop-pause-processing.html

void keyPressed() {
  final int k = keyCode;

  if (k == 'S')
    if (looping)  {
      noLoop();
    } else {
      loop();
    }
}

Why Processing know the var looping it declared no where ?

isLooping() is a boolean method already defined in the Processing core, see here.

Processing library got lotsa public & protected members (methods & fields) which aren't meant to be "revealed" to us, but for other 3rd-party libraries. :-@

Supposedly we should only use those members cited at the "official" reference below: :-\"

Remember that a ".pde" sketch is nothing more than a subclass of class PApplet: L-)
