用一个事件加入和事件与用合并节点加入事件然后用一个事件加入合并节点有什么区别。

最佳答案

据我了解 UML 规范:

A merge node is a control node that brings together multiple alternate flows. It is not used to synchronize concurrent flows but to accept one among several alternate flows. All tokens offered on incoming edges are offered to the outgoing edge. There is no synchronization of flows or joining of tokens.

另一方面,

... an action can only begin execution when it has been offered control tokens on all incoming control flows and all its input pins have been offered object tokens sufficient for their multiplicity. The action begins execution by accepting all the offers of control and object tokens allowed by input pin multiplicity.
