A constructor parameter decorator that tells the DI framework that dependency resolution should start from the parent injector.
说明
In the following example, the dependency can be resolved when instantiating a child, but not when instantiating the class itself.
class Dependency {} @Injectable() class NeedsDependency { constructor(@SkipSelf() public dependency: Dependency) { this.dependency = dependency; } } const parent = ReflectiveInjector.resolveAndCreate([Dependency]); const child = parent.resolveAndCreateChild([NeedsDependency]); expect(child.get(NeedsDependency).dependency instanceof Dependency).toBe(true); const inj = ReflectiveInjector.resolveAndCreate([Dependency, NeedsDependency]); expect(() => inj.get(NeedsDependency)).toThrowError();
