ChangeDetectorRef class abstract

Provides influence over how change detection should execute for a component.

In practice, this is often used just for markForCheck, which sets a component that uses ChangeDetectionStrategy.OnPush as dirty for future change detection.

NOTE: This API is currently transitional. Please use carefully, and avoid methods that are marked @Deprecated(...), as they will be eventually removed entirely.
