检查导入节点是否有可用更新并更新参考需求

打开实时脚本

此示例显示如何检查导入节点是否有可用的更新并更新引用需求。

加载crs_req需求集。

rs = slreq.load("crs_req");

获取需求集的导入节点的句柄。

topRef = children(rs);

检查导入节点是否有可用的更新。

tf = hasNewUpdate(topRef)

tf = logical
   1

1 的结果意味着 topRef 自上次导入后已经更新。更新导入节点下引用需求。

[status,changelist] = updateFromDocument(topRef)

status = 
'Update completed. Refer to Comments on Import1.'

changelist =
