シーケンス図

Sequence Diagram

基本的な例

Basic examples

シーケンス -> を、2つの分類子間のメッセージを描画するために使います。 分類子を、明示的に宣言する必要はありません。

点線の矢印を使う場合は、--> とします。

また、<-<-- を使うこともできます。 これらによって図の見た目が変わることはありませんが、可読性を高めることができます。 ただし、以上の方法はシーケンス図だけに当てはまります。ほかの種類の図には当てはまりません。

@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml

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

分類子の宣言

Declaring participant

キーワード participant を使って分類子を宣言すると、分類子の表示を調整することができます。

宣言した順序が、デフォルトの表示順になります。

分類子の宣言に別のキーワードを使用すると、分類子の形を変えることができます:
  • 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

キーワード as を使って分類子の名前を変更することができます。

アクターや分類子の背景色を、HTML コードや色名を使って変更することもできます。

@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
  '/

Alice->Bob: Authentication Request
Bob->Alice: Authentication Response
Bob->L: Log transaction
@enduml

orderキーワードを使って、分類子が表示される順序を変更することもできます。

@startuml
participant Last order 30
participant Middle order 20
participant First order 10
@enduml

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
  '/

Alice->Bob: Authentication Request
Bob->Alice: Authentication Response
Bob->L: Log transaction
@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

分類子名にアルファベット以外を使う

Use non-letters in participants

分類子を定義するときに引用符を使用することができます。そして、分類子にエイリアスを与えるためにキーワード as を使用することができます。

@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

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

自分自身へのメッセージ

Message to Self

分類子は自分自身へメッセージを送信できます。

\n を使用して、複数行のテキストを扱えます。

@startuml
Alice -> Alice: This is a signal to self.\nIt also demonstrates\nmultiline \ntext
@enduml

@startuml
Alice <- Alice: This is a signal to self.\nIt also demonstrates\nmultiline \ntext
@enduml

[Ref. QA-1361]

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
@enduml

@startuml
Alice <- Alice: This is a signal to self.\nIt also demonstrates\nmultiline \ntext
@enduml

[Ref. QA-1361]

テキストの位置

Text alignment

skinparam sequenceMessageAlignを使用すると、矢印に表示するテキストの位置をleftrightcenterに設定することができます。

directionまたはreverseDirectionを使用すると、矢印の方向に応じてテキストの位置が決定されます。この機能の詳細はskinparamのページを参照してください。

@startuml
skinparam sequenceMessageAlign right
Bob -> Alice : Request
Alice -> Bob : Response
@enduml

応答メッセージのテキストを矢印の下に表示する

skinparam responseMessageBelowArrow trueコマンドを使用すると、応答メッセージのテキストを矢印の下に表示することができます。

@startuml
skinparam responseMessageBelowArrow true
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

Text alignment on arrows can be set to left, right or center using skinparam sequenceMessageAlign.

You can also use direction or reverseDirection to align text depending on arrow direction. Further details and examples of this are available on the skinparam page.

@startuml
skinparam sequenceMessageAlign right
Bob -> Alice : Request
Alice -> Bob : Response
@enduml

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

矢印の見た目を変える

Change arrow style

矢印の見た目をいくつかの方法によって変更できます。
  • メッセージの消失を示す最後の x を追加
  • \/<> の代わりに使うと
  • 矢印の先端が上側だけまたは下側だけになります。
  • 矢印の先端を繰り返す (たとえば >>//) と、矢印の先端が細くなります。
  • --- の代わりに使うと、矢印が点線になります。
  • 矢じりに最後の "O" を追加
  • 双方向の矢印を使用する

@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

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

矢印の色を替える

Change arrow color

以下の表記を使って、個々の矢印の色を変えることができます。

@startuml
Bob -[#red]> Alice : hello
Alice -[#0000FF]->Bob : ok
@enduml

You can change the color of individual arrows using the following notation:

@startuml
Bob -[#red]> Alice : hello
Alice -[#0000FF]->Bob : ok
@enduml

メッセージシーケンスの番号付け

Message sequence numbering

メッセージへ自動で番号を振るために、キーワード autonumber を使います。

@startuml
autonumber
Bob -> Alice : Authentication Request
Bob <- Alice : Authentication Response
@enduml

autonumber <開始> で開始番号を、また、autonumber <開始> <増分> で増分も指定することができます。

@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

二重引用符で囲って番号の書式を指定することができます。

その書式指定は Java の DecimalFormat 方式で行います。 (0 は桁を表し, # は存在しない場合は 0 で埋める桁を意味します)。

一部のHTMLタグを書式に使うこともできます。

@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

autonumber stopautonumber resume <増分> <書式> を自動採番の一時停止と再開にそれぞれ使用することができます。

@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

開始番号は、2つまたは3つの部分からなる数字の列を指定することもできます。各部分は.;,:またはこれらの組み合わせで区切ります。例えば、1.1.11.1:1のようにします。

自動的に最後の数字が増加していきます。

最初の数字を増加させるにはautonumber inc Aを、2番目の数字を増加させるにはautonumber inc Bを使用します。

@startuml
autonumber 1.1.1
Alice -> Bob: Authentication request
Bob --> Alice: Response

autonumber inc A
'Now we have 2.1.1
Alice -> Bob: Another authentication request
Bob --> Alice: Response

autonumber inc B
'Now we have 2.2.1
Alice -> Bob: Another authentication request
Bob --> Alice: Response

autonumber inc A
'Now we have 3.1.1
Alice -> Bob: Another authentication request
autonumber inc B
'Now we have 3.2.1
Bob --> Alice: Response
@enduml

現在のautonumberの値は%autonumber%変数で参照することができます:

@startuml
autonumber 10
Alice -> Bob
note right
  the <U+0025>autonumber<U+0025> works everywhere.
  Here, its value is ** %autonumber% **
end note
Bob --> Alice: //This is the response %autonumber%//
@enduml

[Ref. QA-7119]

The keyword autonumber is used to automatically add an incrementing 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
@enduml

Your startnumber can also be a 2 or 3 digit sequence using a field delimiter such as ., ;, ,, : or a mix of these. For example: 1.1.1 or 1.1:1.

Automatically the last digit will increment.

To increment the first digit, use: autonumber inc A. To increment the second digit, use: autonumber inc B.

@startuml
autonumber 1.1.1
Alice -> Bob: Authentication request
Bob --> Alice: Response

autonumber inc A
'Now we have 2.1.1
Alice -> Bob: Another authentication request
Bob --> Alice: Response

autonumber inc B
'Now we have 2.2.1
Alice -> Bob: Another authentication request
Bob --> Alice: Response

autonumber inc A
'Now we have 3.1.1
Alice -> Bob: Another authentication request
autonumber inc B
'Now we have 3.2.1
Bob --> Alice: Response
@enduml

You can also use the value of autonumber with the %autonumber% variable:

@startuml
autonumber 10
Alice -> Bob
note right
  the <U+0025>autonumber<U+0025> works everywhere.
  Here, its value is ** %autonumber% **
end note
Bob --> Alice: //This is the response %autonumber%//
@enduml

[Ref. QA-7119]

タイトル、ヘッダー、フッター

Page Title, Header and Footer

titleキーワードはページにタイトルをつけるのに使われます。

headerfooterを使うことにより、ページにヘッダーやフッターをつけて表示することができます。

@startuml

header Page Header
footer Page %page% of %lastpage%

title Example Title

Alice -> Bob : message 1
Alice -> Bob : message 2

@enduml

The title keyword is used to add a title to the page.

Pages can display headers and footers using header and footer.

@startuml

header Page Header
footer Page %page% of %lastpage%

title Example Title

Alice -> Bob : message 1
Alice -> Bob : message 2

@enduml

図の分割

Splitting diagrams

図を複数の画像に分けるためにキーワード newpage を使います。

新しいページのタイトルをキーワード newpage の直後に書くことができます。

これは、複数ページにわたる長い図を書くときに便利な機能です。

@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

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.)

@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

メッセージのグループ化

Grouping message

次のキーワードを使えば、メッセージをまとめてグループ化できます。
  • alt/else
  • opt
  • loop
  • par
  • break
  • critical
  • group表示するテキスト

ヘッダ部分に文字列を追加することが可能です。(groupについては、後述の「groupの2つ目のラベル」を参照)

グループを閉じるにはキーワード end を使用します。

注:グループはネスト可能です。

@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

It is possible to group messages together using the following keywords:
  • alt/else
  • opt
  • loop
  • par
  • break
  • critical
  • group, followed by a text to be displayed

It is possible to add a text that will be displayed into the header (for group, see next paragraph 'Secondary group label').

The end keyword is used to close the group.

Note that it is possible to nest groups.

@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

groupの2つ目のラベル

Secondary group label

groupでは、[]の間に2つ目のラベルを設定し、ヘッダに表示させることができます。

@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

[Ref. QA-2503]

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

[Ref. QA-2503]

メッセージに付けるノート

Notes on messages

メッセージのすぐ後ろにキーワード note left または note right を使用し、メッセージにノートを付けることが可能です。

end note キーワードを使って、複数行のノートを作ることができます。

@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

It is possible to put notes on message using the note left or note right keywords just after the message.

You can have a multi-line note using the end note keywords.

@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

end note
@enduml

その他のノート

Some other notes

note left ofnote right ofnote overのキーワードを使って、分類子からの相対位置を指定してノートを配置することもできます。

ノートを目立たせるために、背景色を変えることができます。

また、キーワード end note を使って複数行のノートを作ることができます。

@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

It is also possible to place notes relative to participant with note left of , note right of or note over keywords.

It is possible to highlight a note by changing its background color.

You can also have a multi-line note using the end note keywords.

@startuml
participant Alice

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

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

間隔

Space

図の間隔を調整するために、記号|||を使用することができます。

さらにピクセル数を指定することもできます。

@startuml

Alice -> Bob: message 1
Bob --> Alice: ok
|||
Alice -> Bob: message 2
Bob --> Alice: ok
||45||
Alice -> Bob: message 3
Bob --> Alice: ok

@enduml

You can use ||| to indicate some spacing in the diagram.

It is also possible to specify a number of pixel to be used.

@startuml

Alice -> Bob: message 1
Bob --> Alice: ok
|||
Alice -> Bob: message 2
Bob --> Alice: ok
||45||
Alice -> Bob: message 3
Bob --> Alice: ok

ライフラインの活性化と破棄

Lifeline Activation and Destruction

activatedeactivate を使って分類子の活性化を表します。

分類子の活性化はライフラインで表されます。

activatedeactivate は直前のメッセージに適用されます。

destroy は分類子のライフラインが終わったことを表します。

@startuml
participant User

User -> A: DoWork
activate A

A -> B: << createRequest >>
activate B

B -> C: DoWork
activate C
C --> B: WorkDone
destroy C

B --> A: RequestCreated
deactivate B

A -> User: Done
deactivate A

@enduml

ライフラインはネスト(入れ子に)することができ、色をつけることもできます。

@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
deactivate A
A -> User: Done
deactivate A

@enduml

自動的に活性化(autoactivate)することもできます。この場合はreturnキーワードを使用します。

@startuml
autoactivate on
alice -> bob : hello
bob -> bob : self call
bill -> bob #005500 : hello from thread 2
bob -> george ** : create
return done in thread 2
return rc
bob -> george !! : delete
return success

@enduml

The activate and deactivate are used to denote participant activation.

Once a participant is activated, its lifeline appears.

The activate and deactivate apply on the previous message.

The destroy denote the end of the lifeline of a participant.

@startuml
participant User

User -> A: DoWork
activate A

A -> B: << createRequest >>
activate B

B -> C: DoWork
activate C
C --> B: WorkDone
destroy C

B --> A: RequestCreated
deactivate B

A -> User: Done
deactivate A

@enduml

Nested lifeline can be used, and it is possible to add a color on the lifeline.

@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
deactivate A
A -> User: Done
deactivate A

@enduml

Autoactivation is possible and works with the return keywords:

@startuml
autoactivate on
alice -> bob : hello
bob -> bob : self call
bill -> bob #005500 : hello from thread 2
bob -> george ** : create
return done in thread 2
return rc
bob -> george !! : delete
return success

@enduml

Return

Return

新しいコマンドreturnは、リターンメッセージを生成し、オプションでテキストラベルをつけることができます。 リターンする先は最も最近活性化したライフラインです。 構文は単純にreturn ラベルです。ラベルを与える場合には、通常のメッセージに与えることが可能な文字列を何でも与えることができます。

@startuml
Bob -> Alice : hello
activate Alice
Alice -> Alice : some action
return bye
@enduml

Command return generates a return message with optional text label.

The return point is that which caused the most recent life-line activation.

The syntax is return label where label if provided is any string acceptable for conventional messages.

@startuml
Bob -> Alice : hello
activate Alice
Alice -> Alice : some action
return bye
@enduml

分類子の生成

Participant creation

キーワード create を、オブジェクトが最初のメッセージを受信する直前に置くことにより、このメッセージがオブジェクトを新しく 生成 していることを強調して表現できます。

@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

You can use the create keyword just before the first reception of a message to emphasize the fact that this message is actually creating this new object.

@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

活性化、非活性化、生成のショートカット記法

Shortcut syntax for activation, deactivation, creation

対象の分類子を記述した直後に、次の記法を使うことができます。

  • ++ 対象を活性化する (続けてを記述することもできます)
  • -- 起点側を非活性化する
  • ** 対象のインスタンスを生成する
  • !! 対象のインスタンスを破棄する

@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

同じ行に活性化と非活性化を混ぜることもできます:

@startuml
alice   ->  bob     ++   : hello1
bob     ->  charlie --++ : hello2
charlie --> alice   --   : ok
@enduml

@startuml
@startuml
alice -> bob   --++ #gold: hello
bob   -> alice --++ #gold: you too
alice -> bob   --: step1
alice -> bob   : step2
@enduml
@enduml

[Ref. QA-4834, QA-9573 and QA-13234]

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

Then you can mix activation and deactivation, on same line:

@startuml
alice   ->  bob     ++   : hello1
bob     ->  charlie --++ : hello2
charlie --> alice   --   : ok
@enduml

@startuml
@startuml
alice -> bob   --++ #gold: hello
bob   -> alice --++ #gold: you too
alice -> bob   --: step1
alice -> bob   : step2
@enduml
@enduml

[Ref. QA-4834, QA-9573 and QA-13234]

インとアウトのメッセージ

Incoming and outgoing messages

図の一部だけにフォーカスを当てたい場合には、「外から入ってくる」または「外に出ていく」メッセージを使えます。

左角括弧 "[" を使って図の左端、 右角括弧 "]" を使って図の右側を表せます。

@startuml
[-> A: DoWork

activate A

A -> A: Internal call
activate A

A ->] : << createRequest >>

A<--] : RequestCreated
deactivate A
[<- A: Done
deactivate A
@enduml

また、次の書き方も使えます:

@startuml
participant Alice
participant Bob #lightblue
Alice -> Bob
Bob -> Carol
...
[-> Bob
[o-> Bob
[o->o Bob
[x-> Bob
...
[<- Bob
[x<- Bob
...
Bob ->]
Bob ->o]
Bob o->o]
Bob ->x]
...
Bob <-]
Bob x<-]

@enduml

You can use incoming or outgoing arrows if you want to focus on a part of the diagram.

Use square brackets to denote the left "[" or the right "]" side of the diagram.

@startuml
[-> A: DoWork

activate A

A -> A: Internal call
activate A

A ->] : << createRequest >>

A<--] : RequestCreated
deactivate A
[<- A: Done
deactivate A
@enduml

You can also have the following syntax:

@startuml
participant Alice
participant Bob #lightblue
Alice -> Bob
Bob -> Carol
...
[-> Bob
[o-> Bob
[o->o Bob
[x-> Bob
...
[<- Bob
[x<- Bob
...
Bob ->]
Bob ->o]
Bob o->o]
Bob ->x]
...
Bob <-]
Bob x<-]

@enduml

インとアウトのメッセージに短い矢印を使う

Short arrows for incoming and outgoing messages

?短い矢印を使用することができます。

@startuml
?-> Alice    : ""?->""\n**short** to actor1
[-> Alice    : ""[->""\n**from start** to actor1
[-> Bob      : ""[->""\n**from start** to actor2
?-> Bob      : ""?->""\n**short** to actor2
Alice ->]    : ""->]""\nfrom actor1 **to end**
Alice ->?    : ""->?""\n**short** from actor1
Alice -> Bob : ""->"" \nfrom actor1 to actor2
@enduml

[Ref. QA-310]

You can have short arrows with using ?.

@startuml
?-> Alice    : ""?->""\n**short** to actor1
[-> Alice    : ""[->""\n**from start** to actor1
[-> Bob      : ""[->""\n**from start** to actor2
?-> Bob      : ""?->""\n**short** to actor2
Alice ->]    : ""->]""\nfrom actor1 **to end**
Alice ->?    : ""->?""\n**short** from actor1
Alice -> Bob : ""->"" \nfrom actor1 to actor2
@enduml

[Ref. QA-310]

アンカーと持続時間

Anchors and Duration

teozを使用するとダイアグラムにアンカーを追加することができ、それによって持続時間を表現することができます。

@startuml
!pragma teoz true

{start} Alice -> Bob : start doing things during duration
Bob -> Max : something
Max -> Bob : something else
{end} Bob -> Alice : finish

{start} <-> {end} : some time

@enduml

コマンドライン-Pオプションを使用してpragmaを指定することもできます:

java -jar plantuml.jar -Pteoz=true

[Ref. issue-582]

With teoz it is possible to add anchors to the diagram and use the anchors to specify duration time.

@startuml
!pragma teoz true

{start} Alice -> Bob : start doing things during duration
Bob -> Max : something
Max -> Bob : something else
{end} Bob -> Alice : finish

{start} <-> {end} : some time

@enduml

You can use the -P command-line option to specify the pragma:

java -jar plantuml.jar -Pteoz=true

[Ref. issue-582]

ステレオタイプとスポット

Stereotypes and Spots

<<>> を使い分類子にステレオタイプをつけることができます。

(X,color) と記述することによりステレオタイプに色付きの文字と円のアイコンをつけることができます。

@startuml

participant "Famous Bob" as Bob << Generated >>
participant Alice << (C,#ADD1B2) Testable >>

Bob->Alice: First message

@enduml

デフォルトでは guillemet キャラクターがステレオタイプを表示するために使用されます。 スキンパラメータ guillemet を使用してこの動作を変更することができます:

@startuml

skinparam guillemet false
participant "Famous Bob" as Bob << Generated >>
participant Alice << (C,#ADD1B2) Testable >>

Bob->Alice: First message

@enduml

@startuml

participant Bob << (C,#ADD1B2) >>
participant Alice << (C,#ADD1B2) >>

Bob->Alice: First message

@enduml

It is possible to add stereotypes to participants using << and >>.

In the stereotype, you can add a spotted character in a colored circle using the syntax (X,color).

@startuml

participant "Famous Bob" as Bob << Generated >>
participant Alice << (C,#ADD1B2) Testable >>

Bob->Alice: First message

@enduml

By default, the guillemet character is used to display the stereotype. You can change this behavious using the skinparam guillemet:

@startuml

skinparam guillemet false
participant "Famous Bob" as Bob << Generated >>
participant Alice << (C,#ADD1B2) Testable >>

Bob->Alice: First message

@enduml

@startuml

participant Bob << (C,#ADD1B2) >>
participant Alice << (C,#ADD1B2) >>

Bob->Alice: First message

特有のskinparam

Specific SkinParameter

デフォルト

@startuml
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

ライフラインの設定(lifelineStrategy)

  • nosolid(デフォルト)

@startuml
skinparam lifelineStrategy nosolid
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

[Ref. QA-9016]

  • solid
シーケンス図のライフラインを実線で表示するには、skinparam lifelineStrategy solidを設定します:

@startuml
skinparam lifelineStrategy solid
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

[Ref. QA-2794]

厳密なUMLスタイル(style strictuml)

厳密なUMLに準拠する(矢印の端を矢じり形ではなく三角形にする等)には、次のようにします:
  • skinparam style strictuml

@startuml
skinparam style strictuml
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

[Ref. QA-1047]

By default

@startuml
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

LifelineStrategy

  • nosolid (by default)

@startuml
skinparam lifelineStrategy nosolid
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

[Ref. QA-9016]

  • solid
In order to have solid life line in sequence diagrams, you can use: skinparam lifelineStrategy solid

@startuml
skinparam lifelineStrategy solid
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

[Ref. QA-2794]

style strictuml

To be conform to strict UML (for arrow style: emits triangle rather than sharp arrowheads), you can use:
  • skinparam style strictuml

@startuml
skinparam style strictuml
Bob -> Alice : hello
Alice -> Bob : ok
@enduml

[Ref. QA-1047]

未接続の分類子を表示しない

Hide unlinked participant

デフォルトでは、すべての分類子が表示されます。

@startuml
participant Alice
participant Bob
participant Carol

Alice -> Bob : hello
@enduml

hide unlinkedを指定すると、接続されていない分類子を非表示にできます。

@startuml
hide unlinked
participant Alice
participant Bob
participant Carol

Alice -> Bob : hello
@enduml

[Ref. QA-4247]

By default, all participants are displayed.

@startuml
participant Alice
participant Bob
participant Carol

Alice -> Bob : hello
@enduml

But you can hide unlinked participant.

@startuml
hide unlinked
participant Alice
participant Bob
participant Carol

Alice -> Bob : hello
@enduml

[Ref. QA-4247]

グループメッセージに色を付ける

Color a group message

グループメッセージにを付けることができます:

@startuml
Alice -> Bob: Authentication Request
alt#Gold #LightBlue Successful case
    Bob -> Alice: Authentication Accepted
else #Pink Failure
    Bob -> Alice: Authentication Rejected
end
@enduml

[Ref. QA-4750 and QA-6410]

It is possible to color a group messages:

@startuml
Alice -> Bob: Authentication Request
alt#Gold #LightBlue Successful case
    Bob -> Alice: Authentication Accepted
else #Pink Failure
    Bob -> Alice: Authentication Rejected
end
@enduml

[Ref. QA-4750 and QA-6410]
