在
PHP Framework Interop Group site(PSR的维护者),有一个草稿
PSR-8 Huggable Interface：
原文链接：https://www.f2er.com/php/132600.htmlnamespace Psr\Hug;
/**
* Defines a huggable object.
*
* A huggable object expresses mutual affection with another huggable object.
*/
interface Huggable
{
/**
* Hugs this object.
*
* All hugs are mutual. An object that is hugged MUST in turn hug the other
* object back by calling hug() on the first parameter. All objects MUST
* implement a mechanism to prevent an infinite loop of hugging.
*
* @param Huggable $h
* The object that is hugging this object.
*/
public function hug(Huggable $h);
}
草案很短,但没有提供任何实施的例子.实现这个界面的目的是什么？@H_404_4@
