JhiEventManager 多个订阅
JhiEventManager multiple subscriptions
JhiEventManager 是否允许多个订阅,或者我应该为每个事件单独订阅吗? destroy() JhiEventManager 的方法是否也会处理多个订阅?
export class SomeComponent implements OnInit, OnDestroy {
eventSubscriber?: Subscription;
constructor(protected eventManager: JhiEventManager) {
}
ngOnInit(): void {
this.registerChanges();
}
registerChanges(): void {
this.eventSubscriber = this.eventManager.subscribe('first EntityListModification', () => this.someaction());
// ??? chain this to the same eventSubscriber ???
this.eventManager.subscribe('secondEntityListModification', () => this.someaction());
}
ngOnDestroy(): void {
if (this.eventSubscriber) {
this.eventManager.destroy(this.eventSubscriber);
}
}
非常感谢
基于 current implementation of JhiEventManager 可以一次处理内容 订阅:
export class SomeComponent implements OnInit, OnDestroy {
subscription?: Subscription;
constructor(protected eventManager: JhiEventManager) {}
ngOnInit(): void {
this.registerAllEvents();
}
registerAllEvents(): void {
this.subscription = this.eventManager.subscribe('event1', () => this.loadAll());
this.subscription.add(this.eventManager.subscribe('event2', () => this.loadAll()));
this.subscription.add(this.eventManager.subscribe('event3', () => this.loadAll()));
...
this.subscription.add(this.eventManager.subscribe('eventN', () => this.loadAll()));
}
ngOnDestroy(): void {
if (this.subscription) {
this.eventManager.destroy(this.subscription);
}
}
详细说明请参考https://rxjs-dev.firebaseapp.com/guide/subscription:
call to an unsubscribe() of one Subscription may unsubscribe multiple
Subscriptions. You can do this by "adding" one subscription into
another:
