"Bob()" -> "This is very\nlong" as Long
' You can also declare:
' "Bob()" -> Long as "This is very\nlong"
Long --> "Bob()" : ok

对消息序列编号
关键字 autonumber 用于自动对消息编号。
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
@enduml
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber 15
Bob -> Alice : Another authentication Request
Bob <- Alice : Another authentication Response
autonumber 40 10
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
你可以在双引号内指定编号的格式。 格式是由 Java 的DecimalFormat类实现的: (0 表示数字;# 也表示数字,但默认为0)。 你也可以用 HTML 标签来制定格式。
@startuml
autonumber "<b>[000]"
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber 15 "<b>(<u>##</u>)"
Bob -> Alice : Another authentication Request
Bob <- Alice : Another authentication Response
autonumber 40 10 "<font color=red><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
@enduml
@startuml
autonumber 10 10 "<b>[000]"
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
autonumber stop
Bob -> Alice : dummy
autonumber resume "<font color=red><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response
autonumber stop
Bob -> Alice : dummy
autonumber resume 1 "<font color=blue><b>Message 0 "
Bob -> Alice : Yet another authentication Request
Bob <- Alice : Yet another authentication Response

分割示意图
关键字 newpage 用于把一张图分割成多张。 在 newpage 之后添加文字,作为新的示意图的标题。 这样就能很方便地在 Word 中将长图分几页打印。
@startuml
Alice -> Bob : message 1
Alice -> Bob : message 2
newpage
Alice -> Bob : message 3
Alice -> Bob : message 4
newpage A title for the\nlast page
Alice -> Bob : message 5
Alice -> Bob : message 6
@enduml
组合消息
我们可以通过以下关键词将组合消息:
alt/else
opt
loop
par
break
critical
group, 后面紧跟着消息内容
可以在标头(header)添加需要显示的文字(group除外)。 关键词 end 用来结束分组。 注意,分组可以嵌套使用。
@startuml
Alice -> Bob: Authentication Request
alt successful case
Bob -> Alice: Authentication Accepted
else some kind of failure
Bob -> Alice: Authentication Failure
group My own label
Alice -> Log : Log attack start
loop 1000 times
Alice -> Bob: DNS Attack
end
Alice -> Log : Log attack end
end
else Another type of failure
Bob -> Alice: Please repeat
end
@enduml

Secondary group label
For group, it is possible to add, between[ and ], a secondary text or label that will be displayed into the header.
@startuml
Alice -> Bob: Authentication Request
Bob -> Alice: Authentication Failure
group My own label [My own label 2]
Alice -> Log : Log attack start
loop 1000 times
Alice -> Bob: DNS Attack
end
Alice -> Log : Log attack end
end
@enduml
我们可以通过在消息后面添加 note left 或者 note right 关键词来给消息添加注释。 你也可以通过使用 end note 来添加多行注释。
@startuml
Alice->Bob : hello
note left: this is a first note
Bob->Alice : ok
note right: this is another note
Bob->Bob : I am thinking
note left
a note
can also be defined
on several lines
end note
@enduml
其他的注释
可以使用note left of,note right of或note over在节点(participant)的相对位置放置注释。 还可以通过修改背景色来高亮显示注释。 以及使用关键字end note来添加多行注释。
@startuml
participant Alice
participant Bob
note left of Alice #aqua
This is displayed
left of Alice.
end note
note right of Alice: This is displayed right of Alice.
note over Alice: This is displayed over Alice.
note over Alice, Bob #FFAAAA: This is displayed\n over Bob and Alice.
note over Bob, Alice
This is yet another
example of
a long note.
end note
@enduml
改变备注框的形状
你可以使用 hnote 和 rnote 这两个关键字来修改备注框的形状。
@startuml
caller -> server : conReq
hnote over caller : idle
caller <- server : conConf
rnote over server
"r" as rectangle
"h" as hexagon
endrnote
@enduml
You can directly make a note over all participants, with the syntax:
note across: note_description
@startuml
Alice->Bob:m1
Bob->Charlie:m2
note over Alice, Charlie: Old method for note over all part. with:\n ""note over //FirstPart, LastPart//"".
note across: New method with:\n""note across""
Bob->Alice
hnote across:Note across all part.

end note
Alice -> Bob : A //well formatted// message
note right of Alice

分隔符
你可以通过使用 == 关键词来将你的图表分割多个步骤。

@enduml
延迟
你可以使用...来表示延迟,并且还可以给延迟添加注释。
@startuml
Alice -> Bob: Authentication Request
...
Bob --> Alice: Authentication Response
...5 minutes latter...
Bob --> Alice: Bye !
@enduml
Text wrapping
To break long messages, you can manually add \n in your text. Another option is to use maxMessageSize setting:
@startuml
skinparam maxMessageSize 50
participant a
participant b
a -> b :this\nis\nmanually\ndone
a -> b :this is a very long message on several words
@enduml
空间
你可以使用|||来增加空间。 还可以使用数字指定增加的像素的数量。
@startuml
Alice -> Bob: message 1
Bob --> Alice: ok
|||
Alice -> Bob: message 2
Bob --> Alice: ok
||45||
Alice -> Bob: message 3
Bob --> Alice: ok

activate B
B -> C: DoWork
activate C
C --> B: WorkDone
destroy C
B --> A: RequestCreated
deactivate B
A -> User: Done
deactivate A
@enduml
还可以使用嵌套的生命线,并且运行给生命线添加颜色。
@startuml
participant User
User -> A: DoWork
activate A #FFBBBB
A -> A: Internal call
activate A #DarkSalmon
A -> B: << createRequest >>
activate B
B --> A: RequestCreated
deactivate B

Return
A new command return for generating a return message with optional text label. The point returned to is the point that cause the most recently activated life-line. The syntax is simply return label where label, if provided, can be any string acceptable on conventional messages.
@startuml
Bob -> Alice : hello
activate Alice
Alice -> Alice : some action
return bye
@enduml
创建参与者
你可以把关键字create放在第一次接收到消息之前,以强调本次消息实际上是在创建新的对象。
@startuml
Bob -> Alice : hello
create Other
Alice -> Other : new
create control String
Alice -> String
note right : You can also put notes!
Alice --> Bob : ok
@enduml
Shortcut syntax for activation, deactivation, creation
Immediately after specifying the target participant, the following syntax can be used:
++ Activate the target (optionally a #color may follow this)
-- Deactivate the source
** Create an instance of the target
!! Destroy an instance of the target
@startuml
alice -> bob ++ : hello
bob -> bob ++ : self call
bob -> bib ++ #005500 : hello
bob -> george ** : create
return done
return rc
bob -> george !! : delete
return success
@enduml
进入和发出消息
如果只想关注部分图示,你可以使用进入和发出箭头。 使用方括号[和]表示图示的左、右两侧。
@startuml
[-> A: DoWork
activate A
A -> A: Internal call
activate A
A ->] : << createRequest >>
A<--] : RequestCreated
deactivate A
[<- A: Done
deactivate A
@enduml
还可以使用下面的语法:
@startuml

[x<- Bob
Bob ->]
Bob ->o]
Bob o->o]
