PHPStorm类型提示子类的基类 [英] PHPStorm type hinting subclasses of baseclass

问题描述

关于此帖子:

在PHPStorm中，当我有一个超类方法返回每个子类的不同类型时，如何使类型提示起作用，

这是关于PHPStorm类型提示中的一种极端情况. 请尝试遵循-我会尽力做到尽可能清楚:

this one is about an edge case in PHPStorm type hinting. Please try to follow along - I'll do my best to be as clear as possible:

所以，我有了这个基本的抽象类:

So, I've got this base abstract class:

abstract class myBaseController {
    protected $_model;
    ...
}

另一个类继承自的内容:

which another class inherits from:

class myController extends myBaseController {
    $hello = 'hello';
    ...
}

，并由第三类进一步扩展:

and which is further extended by a third class:

class myNewController extends myController {
    public $myvar;
    $this->_model = new myModel();
    ...

    public function myFunc(){
        // !!form is underlined as: "Method 'form' not found in class"!!
        $form = $this->_model->form($new_variable); 
    }

下面是myModel类的示例:

Below is a sample of the myModel class:

class myModel extends BaseModel {
    $world = 'world';
    public function form($my_variable) {
        do_something();
    }

我的真正问题是如何在这种情况下正确"phpdoc":

---

My true question is how to properly "phpdoc" this scenario:

子类使用继承的变量_model来分配另一个具有唯一功能form的类myModel的实例. PHPStorm应该如何正确找到myNewController中的form?

A subclass myNewController is using an inherited variable _model to assign an instance of another class myModel which has a unique function form. How should PHPStorm properly find out about form in myNewController?

到目前为止，我的解决方案包括像这样记录myBaseController:

My solution so far involves documenting myBaseController like this:

abstract class myBaseController {
    /**
     * @var object
     */
     protected $_model;
    ...
}

但是我认为@var object的范围太广(PHPStorm找不到其声明)，我的猜测是应该有一种更好(更具体)的方法来实现此目的.

However I think @var object is too broad (PHPStorm won't find its declaration) and my guess is that there should be a better (and more specific) way to do this.

也许我们可以代替:

/**
 * @var BaseModel
 */

如果PHPStorm可以查看该方法的子类.

if PHPStorm had a way of looking into the subclasses for the method.

有什么想法吗? 谢谢大家.

Any ideas? Thank you all in advance.

推荐答案

您可以使用@property批注在子类中指定属性类型，而无需引入新代码:

You can specify the property type in your subclass without introducing new code, using the @property annotation:

/**
 * @property myModel $_model
 */
class myNewController extends myController
