Angular2 - rxjs观察vs处置？

Question

取消订阅和处理有什么区别？

例如

// app-service.ts 
{Http} from @angular/core; 

export class appService { 
    constructor(private http : Http, fooService : FooService) {} 
    getAll() { 
     // do this 
     this.sub = this.fooService.subscribe(
      () => {}, 
      error => throw new Error(error), 
      () => {} 
     ) 
    } 

    ngOnDestroy() { 
     this.sub.dispose(); 
    } 
} 

Answer 1

它是rxjs4 - rxjs5差;

在rxjs4有Disposable是你们等dispose()，现在他们Subscription是你们等unsubscribe()
