# BatchQueryRelatedObjects
#### 功能介绍
BatchQueryRelatedObjects接口可根据入参，批量查询某源/目标数据模型的信息以及对应的属性列表。
例如，入参为源数据模型，可批量查询目标数据模型信息和属性。
#### 入参
```
{
       "params":{
              "objectIds": [ "XXXX", "XXXX" ],
              "role":"source",
              "latestOnly":false
       }
}
```
- objectIds：对象ID列表。
- role：角色，源数据模型或目标数据模型。
- latestOnly：目标对象是否仅返回源对象关联的最新版本目标对象，默认为false。（仅对M-V模型有效，即返回所有版本）
 
#### 出参
返回查询结果列表。
#### 示例场景
假设有一个源端为RelationLeft，目标端为RelationRight的关系实体（RelationTest）。其中，
- RelationLeft有两个关系实例，唯一编码为454580805678901111和454580805678902222。
- RelationRight有两个关系实例，唯一编码为454580805678903333和454580805678904444。
并创建了如下唯一编码的关系实例：
- 1313：源端为454580805678901111，目标端为454580805678903333。
- 2424：源端为454580805678902222，目标端为454580805678904444。
- 1414：源端为454580805678901111，目标端为454580805678904444。
 
#### 入参示例
根据源端RelationLeft的ID为454580805678901111和454580805678902222的对象实例查询符合条件的目标端对象实例。

              "role":"source",
              "latestOnly":false
       }
}
