PHP xPDO::call方法代码示例

 /**
  * Load a graph of related objects to the current object.
  *
  * @param boolean|string|array|integer $graph An option to tell how to deal with related objects. If integer, will
  * traverse related objects up to a $graph level of depth and load them to the object.
  * If an array, will traverse required related object and load them to the object.
  * If true, will traverse the entire graph and append all related objects to the object (default behavior).
  * @param xPDOCriteria|array|string|integer $criteria A valid xPDO criteria representation.
  * @param boolean|integer $cacheFlag Indicates if the objects should be cached and optionally, by specifying an
  * integer value, for how many seconds.
  * @return array|boolean The graph that was loaded or false if nothing was loaded.
