export class ErrorHandler {
    test() {
        console.log('ErrorHandler.test()');
    }
}

export abstract class BaseApiComponent<T> {
    // use protected property parameter in abstract class
    // for accessibility from descendants.
    constructor(protected errorHandler: ErrorHandler) {}

    someMethod() {
        this.errorHandler.test();
    }
}

export class ApiComponentImpl<T> extends BaseApiComponent<T> {
    // use @Inject decorator
    constructor(@Inject(ErrorHandler) errorHandler: ErrorHandler) {
        super(errorHandler);
    }
}
