const container = new Container();
const standardValidator = {};
container.registerInstance(Validator, standardValidator);
const childContainer = container.createChild();
const factory = childContainer.get(ValidationControllerFactory);
const controller = factory.createForCurrentScope();
expect(controller.validator).toBe(standardValidator);
expect(container.get(Optional.of(ValidationController))).toBe(null);
expect(childContainer.get(Optional.of(ValidationController))).toBe(controller);
const customValidator = {};
expect(factory.createForCurrentScope(customValidator).validator).toBe(customValidator);
});示例2: function
return function(target, key, desc?) {
if (!type) {
// typescript
type = metadata.get(metadataType, target, key);
}
injectFn(target, key, desc, Optional.of(type));
};示例3: function
return function(target, key, desc?) {
if (type === undefined) {
// typescript
