/**
* 从数组中获取值，生成Entity, 该方法会假设row是从数据库查询
* 的结果，请不要直接使用该方法，通过Entity::selector()->find()
* 的方式，它会自动将row包装称Entity
*
* 有时候我们需要关联其他表获取某些字段，我们允许将这些字段附带到这个entity上面
* 这样我们能够获取到更多的灵活性
*
* ###example
*
* ArticleEntity 拥有属性
* title content
*
* PublishedArticleEntity 拥有属性
* atl_id like_num
*
*```php
* $article = PublishedArticleEntity::find('xx')->getArticle(function($selector) {
* $published_selector = PublishedArticleEntity::Selector()
* ->feildLikeNum('like_number') // 通过left join抓取like_num字段的值
* ->onAtlId($selector->getFeildExpr('atl_id'));
* return $selector->join($published_selector);
* });
*
* $total_like_number = $article->getLikeNumber(); // 获取PublishedArticleEntity的属性值
*```
*
* 这样我们可以通过标准的get方法取值，我们把这种通过left join抓取的值称之为伪属性
*
* @param array row 从数据库中查询出来的row信息
*
* @return Entity
