Answer 1

Try this

export class Collection{
public more (): Observable {
   if (this.hasMore()) {
     return this.fetch();
   }
   else{
     return this.returnEmpty(); 
   }            
  }
public returnEmpty(): any {
    let subscription = source.subscribe(
      function (x) {
       console.log('Next: %s', x);
    },
    function (err) {
       console.log('Error: %s', err);
    },
    function () {
       console.log('Completed');
    });
    }
  }
let source = Observable.empty();
