      import { Directive, AfterViewInit, OnDestroy, Optional } from '@angular/core';
import { MatAutocompleteTrigger } from '@angular/material';

@Directive({ selector: '[tab-directive]' })
export class TabDirective implements AfterViewInit, OnDestroy {
  observable: any;
  constructor(@Optional() private autoTrigger: MatAutocompleteTrigger) { }
  ngAfterViewInit() {
    this.observable = this.autoTrigger.panelClosingActions.subscribe(x => {
      if (this.autoTrigger.activeOption) {
        this.autoTrigger.writeValue(this.autoTrigger.activeOption.value)
      }
    })
  }
  ngOnDestroy() {
    this.observable.unsubscribe();
  }
}
