} from '@alphabetabc/core2';

timer

  const timer = new Timer(delay, [count?, callback?]);
  const timer = new Timer(1000, 10); // interval
  const timer = new Timer(Timer.REQUEST_ANIMATION_FRAME); // requestAnimationFrame

  timer.runningStatus // boolean

  timer.start();
  timer.stop();
  timer.reset();
  timer.clear();
  timer.addListener(e => {
       console.log(e); // { type:"timer|completed", count?:number }
  });
  timer.on('timer',() => {});
  timer.on('completed',() => {})

BatchUpdate

const bu = new BatchUpdate();

const updater = () => {
    console.log('log------update');
};
bu.addUpdater(updater);
bu.removeUpdater(updater);
bu.update();

EventDispatcher

直接使用

const dispatch = new EventDispatcher();
dispatch.once(Symbol.for('click'), (...args) => {
    console.log('log------------once', args);
});
dispatch.on(Symbol.for('click'), (...args) => {
    console.log('log------------', args);
});
setTimeout(() => {
    dispatch.emit(Symbol.for('click'), 666);
    console.log('emit');
}, 1000);
setTimeout(() => {
    dispatch.emit(Symbol.for('click'), 8888);
    console.log('emit2');
}, 2000);

创建一个对象

const dispatcher = createEventDispatcher();
dispatcher.on('click', () => {});
dispatcher.emit('click', { value: 6666 });

装饰 function

const Obj: any = function () {};
EventDispatcher.Decorator()(Obj);
const obj = new Obj();

obj.on(Symbol.for('click2'), (...args) => {
    console.log('log------------2222', args);
});
setTimeout(() => {
    obj.emit(Symbol.for('click2'), 8888);
    console.log('emit3');
}, 2000);

装饰 object

const Obj: any = {};
EventDispatcher.Decorator()(Obj);
const obj = Obj;
obj.on(Symbol.for('click2'), (...args) => {
    console.log('log------------object', args);
});
setTimeout(() => {
    obj.emit(Symbol.for('click2'), 8888);
    console.log('object');
}, 2000);

类装饰器

@EventDispatcher.Decorator()
class P {}

const p1 = new P();
// @ts-ignore
p1.on('click', (...args) => {
    console.log('log---------class', args);
});
// @ts-ignore
p1.emit('click', 6666);
const p2 = new P();
// @ts-ignore
// console.log(p2.on);
// console.log(p1.on);
// @ts-ignore
p2.emit('click', 6666);
console.log(p2);

UiComponent

// todo
