使用单例而不是新运算符检索对象时，netbeans自动完成? [英] netbeans autocompletion when using singleton to retrieve object instead of new operator?

问题描述

当我使用'new'运算符实例化一个类时，netbeans可以自动完成对象的成员.

when i use the 'new' operator to instantiate a class, netbeans has no problem to autocomplete the members of the object.

$instance = new Singleton();
$instance-> // shows test() method

但是当我使用单例来检索对象时，它无法自动完成所检索对象中的成员.

but when i use a singleton to retrieve an object it cannot autocomplete the members in the object retrieved.

getInstance代码如下:

the getInstance code looks like this:

public function test() {
    echo "hello";
}

public static function getInstance() {
if ( ! is_object(self::$_instance)) {
    self::$_instance = new self();
    self::$_instance->initialize();
}
return self::$_instance;
}

所以我用:

$instance = Singleton::getInstance();
$instance-> // no autocompletion!

有人有同样的问题吗?

我该如何解决?

谢谢！

推荐答案

在分配$instance之前，您可以添加注释以指示其类型:

You could add a comment to indicate of which type $instance is, before assigning it :

/* @var $instance Singleton */
$instance = Singleton::getInstance();

然后您将获得自动补全:

And you'd get autocompletion :

(已通过最近每晚一次的netbeans测试)

另一种解决方案是在getInstance()方法的声明中添加一个文档块，以指示它返回Singleton类的实例:

Another solution would be to add a docblock to the declaration of your getInstance() method, to indicate that it returns an instance of the Singleton class :

/**
 * @return Singleton
 */
public static function getInstance() {

}

然后，您还将获得自动完成功能:

And, then, you'll also get autocompletion :
