시퀀스 ->는 두 참여자들 사이의 메시지를 그리기 위해 사용된다.
참여자들은 명시적으로 선언하지 않아도 된다.
점선 화살표를 만들기 위해서는 -->를 사용한다.
또한 <-과 <--를 사용할 수 있다.
출력되는 그림은 변경되지 않지만, 가독성을 향상시키는데 사용할 수 있다.
이는 시퀀스 다이어그램에만 적용되며, 다른 다이어그램에는 다른 규칙이 적용된다.
@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml
Basic examples
The sequence -> is used to draw a message between two
participants.
Participants do not have to be explicitly declared.
To have a dotted arrow, you use -->
It is also possible to use <- and <--.
That does not change the drawing, but may improve readability.
Note that this is only true for sequence diagrams, rules are different for the other diagrams.
@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: Another authentication Response
@enduml
참여자(participant) 선언
participant 키워드를 이용하여 참여자의 순서를 바꿀 수 있다.

WARNING
Declaring participant
If the keyword participant is used to declare a participant, more control on that participant is possible.
The order of declaration will be the (default) order of display.
Using these other keywords to declare participants will change the shape of the participant representation:
actor
boundary
control
entity
database
collections
queue
@startuml
participant participant as Foo
actor actor as Foo1
boundary boundary as Foo2
control control as Foo3
entity entity as Foo4
database database as Foo5
collections collections as Foo6
queue queue as Foo7
Foo -> Foo1 : To actor
Foo -> Foo2 : To boundary
Foo -> Foo3 : To control
Foo -> Foo4 : To entity
Foo -> Foo5 : To database
Foo -> Foo6 : To collections
Foo -> Foo7: To queue
@enduml
Rename a participant using the as keyword.
You can also change the background color of
actor or participant.
@startuml
actor Bob #red
' The only difference between actor
'and participant is the drawing
participant Alice
participant "I have a really\nlong name" as L #99FF99
/' You can also declare:
participant L as "I have a really\nlong name" #99FF99

@enduml
You can use the order keyword to customize the display order of participants.
@startuml
participant Last order 30
participant Middle order 20
participant First order 10
@enduml
참여자에서 특수문자 사용하기
따옴표를 사용하여 참여자를 정의할 수 있다.
그리고 "as" 키워드를 사용하여 참여자를 별칭으로 사용 할 수도 있다.
@startuml
Alice -> "Bob()" : Hello
"Bob()" -> "This is very\nlong" as Long
' You can also declare:
' "Bob()" -> Long as "This is very\nlong"
Long --> "Bob()" : ok
@enduml
Use non-letters in participants
You can use quotes to define participants.
And you can use the as keyword to give an alias to those participants.
@startuml
Alice -> "Bob()" : Hello
"Bob()" -> "This is very\nlong" as Long
' You can also declare:
' "Bob()" -> Long as "This is very\nlong"
Long --> "Bob()" : ok
@enduml
자신에게 메시지 보내기
참여자는 자기 자신에게 메시지를 보낼 수 있다.
\n 을 이용해서 여러 줄로 쓰는 것도 가능하다
@startuml
Alice->Alice: This is a signal to self.\nIt also demonstrates\nmultiline \ntext
@enduml
Message to Self
A participant can send a message to itself.
It is also possible to have multi-line using \n.
@startuml
Alice->Alice: This is a signal to self.\nIt also demonstrates\nmultiline \ntext

Text alignment
Text of response message below the arrow
You can put the text of the response message below the arrow, with the skinparam responseMessageBelowArrow true command.
@startuml
skinparam responseMessageBelowArrow true
Bob -> Alice : hello
Alice -> Bob : ok
@enduml
@startuml
Bob ->x Alice
Bob -> Alice
Bob ->> Alice
Bob -\ Alice
Bob \\- Alice
Bob //-- Alice
Bob ->o Alice
Bob o\\-- Alice
Bob <-> Alice
Bob <->o Alice
@enduml
Change arrow style
You can change arrow style by several ways:
add a final x to denote a lost message
use \ or / instead of < or > to have only the bottom or top part of the arrow
repeat the arrow head (for example, >> or //) head to have a thin drawing
use -- instead of - to have a dotted arrow
add a final "o" at arrow head
use bidirectional arrow <->
@startuml
Bob ->x Alice
Bob -> Alice
Bob ->> Alice
Bob -\ Alice
Bob \\- Alice
Bob //-- Alice
Bob ->o Alice
Bob o\\-- Alice
Bob <-> Alice
Bob <->o Alice
@enduml
화살표 색상 변경
다음의 표기법을 이용해서 각각 화살표의 색상을 바꿀 수 있다.
@startuml
Bob -[#red]> Alice : hello
Alice -[#0000FF]->Bob : ok
@enduml
Change arrow color
You can change the color of individual arrows using the following notation:
@startuml
Bob -[#red]> Alice : hello
Alice -[#0000FF]->Bob : ok
@enduml
메시지 순서에 번호 매기기
autonumber 키워드는 메시지에 자동으로 번호를 매길 때에 사용한다.
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
@enduml
autonumber //시작번호// 의 형태로 표시하면 특정 번호로 시작 할 수 있으며, autonumber //시작번호// //증가값// 으로 표시 할 경우 증가 값을 조정하는 것도 가능하다.
@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
쌍따옴표를 이용하여 표시 형식을 바꿀 수도 있다.
표시 형식은 자바 클래스 DecimalFormat 을 사용한다.
(0 은 숫자를 의미하며, # 은 숫자로 표시하되, 빈 자리이면 0 으로 채우라는 뜻이다).
몇 가지 html 태그를 사용 할 수 있다.
@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
또한, autonumber stop 키워드를 이용하여 번호 매김을 일시 정지할 수 있으며, autonumber resume //증가값// //표시형식// 키워드를 이용하여 계속해서 번호를 매길 수 있다.
@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
@enduml
Message sequence numbering
The keyword autonumber is used to
automatically add number to messages.
@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
@enduml
You can specify a startnumber with autonumber //start// , and
also an increment with autonumber //start// //increment//.
@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
You can specify a format for your number by using between double-quote.
The formatting is done with the Java class DecimalFormat
(0 means digit, # means digit and zero if absent).
You can use some html tag in the format.
@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
You can also use autonumber stop and
autonumber resume //increment// //format// to respectively pause and resume
automatic numbering.
@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

다이어그램 분리
newpage 키워드를 이용하여, 다이어그램을 여러 개의 이미지로 분리 할 수 있다.
newpage 키워드 뒤에 바로 새로 생성되는 페이지의 제목을 넣을 수 있다.
여러 페이지에 걸쳐 있는 긴 다이어그램을 출력할 때 유용하다.
(주: 예제에서 첫 번째 페이지만 표시되었지만, 실제로 잘 동작하는 기능이다.)
@startuml

Splitting diagrams
The newpage keyword is used to split a diagram into several images.
You can put a title for the new page just after the newpage
keyword. This title overrides the previously specified title if any.
This is very handy with Word to print long diagram on
several pages.
(Note: this really does work. Only the first page is shown below, but it is a display artifact.)
