ChangeDetectionStrategy

enum

The strategy that the default change detector uses to detect changes. When set, takes effect the next time change detection is triggered.

API

  
    enum ChangeDetectionStrategy {}

OnPush

Use the CheckOnce strategy, meaning that automatic change detection is deactivated until reactivated by setting the strategy to Default (CheckAlways). Change detection can still be explicitly invoked. This strategy applies to all child directives and cannot be overridden.

Default

Use the default CheckAlways strategy, in which change detection is automatic until explicitly deactivated.
