任何人都有Quick Sequence Diagram Editor的经验？即时显示+文本源代码+ Java实现的组合对我来说很有吸引力，但是我不太清楚如何使语法达到我想要的效果，并且文档也不是很清楚。这是一个人为的例子:
al:Actor
bill:Actor
atm:ATM[a]
bank:Bank[a]
al:atm.give me $10
atm:al has $3=bank.check al's account balance
al:atm.what time is it
atm:al.it's now
atm:al.stop bugging me
atm:al.you only have $3
atm:bill.and don't you open your mouth
bill:atm.who asked you?
bill:atm.give me $20
al:atm.hey, I'm not finished!
atm:bill has $765=bank.check bill's account balance
atm:yes I'm sure, bill has $765=bank.hmm are you sure?
atm:bill.here's $20, now go away
atm:great, he's a cool dude=bank.I just gave Bill $20
al:atm.what about my $10?
atm:al.read my lips: you only have $3
这是单线程模式下QSDE的结果:
并在多线程模式下:
我想我不清楚是什么开始/结束那些竖线。我遇到的情况是单线程，但是涉及到状态，并且所有消息都是异步的。我想这意味着我应该使用一个外部对象来表示该状态及其生命周期。我想要的是一个时间轴来表示消息序列
另一个时间轴代表消息序列
另一个“wisecracks”代表我现在不在乎的其他杂项消息。
有没有办法用QSDE做到这一点？
最佳答案
当启动新线程时(并且来自用户的消息始终会启动新线程)，直到明确将其停止或该图结束之前，它不会停止。例如。 atm:stop终止atm线程
这是第一次尝试
(一切都在多线程模式下):
al:Actor
bill:Actor
atm:ATM[a]
bank:Bank[a]
al:atm.give me $10
atm:al has $3=bank.check al's account balance
atm:al.you only have $3
atm:stop
bill:atm.give me $20
atm:bill has $765=bank.check bill's account balance
atm:yes I'm sure, bill has $765=bank.hmm are you sure?
atm:bill.here's $20, now go away
atm:great, he's a cool dude=bank.I just gave Bill $20
带有异步消息的另一个版本
(可以说，消息应该是异步的，因为它们是通过网络传输的。无论如何，现在所有箭头看起来都一样)
消息开头的“>”将启动一个新线程(默认情况下，来自用户和进程的所有消息都将启动一个新线程。)
最后的“＆”表示调用立即返回，并且不显示新线程。您可以使用它来模拟将消息发送到现有线程。
(默认情况下，发送给用户和进程的所有消息总是立即返回。)
al:Actor
bill:Actor
atm:ATM[a]
bank:Bank[a]
al:atm.give me $10
atm:>bank.check al's account balance
bank:>atm.al has $3&
bank:stop
atm:al.you only have $3
atm:stop
bill:atm.give me $20
atm:>bank.check bill's account balance
bank:>atm.bill has $765&
bank:stop
atm:>bank.hmm are you sure?
bank:>atm.yes I'm sure, bill has $765&
bank:stop
atm:bill.here's $20, now go away
atm:>bank.I just gave Bill $20
bank:>atm.great, he's a cool dude&
bank:stop
具有所有明智选择的完整示例
从示例中尚不清楚何时确切停止ATM中的线程。 ATM似乎更像是用户或进程，而不是对象。因此，该示例不一定有意义
al:Actor
bill:Actor
atm:ATM[a]
bank:Bank[a]
al:atm[a].give me $10
atm:al has $3=bank.check al's account balance
al:atm.what time is it
atm:al.it's now
atm:stop
atm:al.stop bugging me
atm:al.you only have $3
atm:bill.and don't you open your mouth
bill:atm.who asked you?&
atm:stop
bill:atm.give me $20
al:atm.hey, I'm not finished!&
atm:bill has $765=bank.check bill's account balance
