A callback method that is invoked immediately after the default change detector has checked the directive's data-bound properties for the first time, and before any of the view or content children have been checked. It is invoked only once when the directive is instantiated.
Precomputed filtered diff tree. Recomputed only when the source data (
diffItems) or the filter inputs (filter/filterType) change — never on every change-detection cycle. Bound directly by the template's@forand empty-state length check, which preserves@forreferential stability between CD passes (the recursive walk no longer runs >= 2x/CD).
