活动图中的每条路径是否都有结束节点。每个“叉子”都是分支需要合并吗?
活动图中的每条路径都需要有一个结束节点吗?类似的问题是每个fork分支都需要合并吗?
我做了一个活动图(如下),但它似乎是错误的。某些分支(来自 fork)没有结束节点(也不以合并结束)。
我的想法是店员会将装运装箱单发送给采购、会计和销售部门。顾客。其中 2 个似乎只是创建/初始化对象(例如输入信息)。它们是并行执行的,所以我觉得我应该有一个分叉?
Does every path in an activity diagram need to have a finish node? A similar question is does every fork branch need to be merged?
I did an activity diagram (below), but it seems wrong. Some branches (from fork) has no finish node (nor end in a merge).
My idea was the clerk will send shipment packing slip to purchashing, accounting & customer. 2 of which just seem to create/init objects (eg. enter info). They are executed in parallel so I felt I should have a fork?

是的。但完成节点有两种:
ActivityFinal
和FlowFinal
。您需要使用FlowFinal
节点终止每个包装和运输流程。有关详细信息,请参阅规范中的第 12.4 节。该符号位于此处,即其所在页面 是一个很好的参考。不。但它需要终止 - 因此存在
FlowFinal
节点。嗯。
Yes. But there are two kinds of finish node:
ActivityFinal
andFlowFinal
. You need to terminate each of the packaging and shipment flows with aFlowFinal
node. See section 12.4 in the spec for details. The symbol is here, the page it's on is a good reference.No. But it needs to terminate - hence existence of
FlowFinal
node.hth.
