var maxObjectCount = 30;
var maxObjectTimeFrameMs = 30000;
var t = new Throttle(maxObjectTimeFrameMs, maxObjectCount);

function incomingObject(obj) {
  // if you want to know what the probability for the next object will be use
  console.log(t.getProbability());
  // decide fate whether this incoming object should be propagated further
