示例1: hook_field_storage_query
/**
* Execute an EntityFieldQuery.
*
* This hook is called to find the entities having certain entity and field
* conditions and sort them in the given field order. If the field storage
* engine also handles property sorts and orders, it should unset those
* properties in the called object to signal that those have been handled.
*
* @param EntityFieldQuery $query
* An EntityFieldQuery.
*
* @return
* See EntityFieldQuery::execute() for the return values.
