ContentChild

Configures a content query.

Content queries are set before the ngAfterContentInit callback is called.

Example

@Directive(selector: 'someDir')
class SomeDir {
  @ContentChild(ChildDirective)
  Query<ChildDirective> contentChild;
 
  @override
  ngAfterContentInit() {
    // contentChild is set
  }
}
