How to listen for child event from parent directiv

问题:

I have a child component 'my-component' which is wrapped by a Directive 'MyDirective' , I need to emit an event to parent directive from the child component, I know how to do it for parent component using @Output but no luck with directive.

<div myDirective >
    <my-component></my-component>
</div>

Any idea?

One approach is to use a template variable and reference it in an event handler:

<div myDirective #mydir>
    <my-component (someEvent)="mydir.someMethod()"></my-component>
</div>
