在我使用的Angular 2 / Ionic 2(final / rc0)项目中的组件中：
protected contentTarget: ViewContainerRef;
ngOnInit() {
this.contentTarget.createComponent(componentFactory);
}
AoT编译器说：
Error at ....: Property 'contentTarget' is protected and only accessible within class 'IncludeTemplateComponent' and its subclasses.
变量(属性)不会在整个项目中的任何其他位置使用.
那么……任何人都可以对此有所了解,是createComponent工厂将contentTarget变量传递给它的子节点,或者为什么编译器不喜欢这里受保护？现在所有Angular2中的受保护变量都是“被禁止的”吗？
从
here起
原文链接：https://www.f2er.com/angularjs/240485.htmlFor a given component all its members (methods,properties) accessed
by its template must be public in the ahead-of-time compilation
scenario. This is due to the fact that a template is turned into a TS
class. A generated class and a component are 2 separate classes now
and you can’t access private members cross-class.
我的看法是,contentTarget由模板引擎使用,因此,AOT必须公开才能工作.
