Diagrammes de composants

Component Diagram

Prenons quelques exemples.

Let's have few examples.

Composants

Components

Les composants doivent être mis entre parenthèses.

Vous pouvez également utiliser le mot-clé component pour définir un composant . Et vous pouvez définir un alias, en utilisant le mot-clé as . Cet alias sera utilisé plus tard, lors de la définition des relations

@startuml

[First component]
[Another component] as Comp2
component Comp3
component [Last\ncomponent] as Comp4

@enduml

Components must be bracketed.

You can also use the component keyword to define a component. And you can define an alias, using the as keyword. This alias will be used later, when defining relations.

@startuml

[First component]
[Another component] as Comp2
component Comp3
component [Last\ncomponent] as Comp4

@enduml

Interfaces

Interfaces

Les interfaces sont définies à l'aide du symbole () (parce que cela ressemble à un cercle).

Vous pouvez aussi utiliser le mot-clé interface pour définir une interface. Vous pouvez aussi définir un alias, à l'aide du mot-clé as. Cet alias pourrait être utilisé plus tard, lors de la définition des relations.

Nous verrons plus tard qu'il n'est pas obligatoire de définir les interfaces.

@startuml

() "First Interface"
() "Another interface" as Interf2
interface Interf3
interface "Last\ninterface" as Interf4

[component]
footer //Adding "component" to force diagram to be a **component diagram**//
@enduml

Interface can be defined using the () symbol (because this looks like a circle).

You can also use the interface keyword to define an interface. And you can define an alias, using the as keyword. This alias will be used latter, when defining relations.

We will see latter that interface definition is optional.

@startuml

() "First Interface"
() "Another interface" as Interf2
interface Interf3
interface "Last\ninterface" as Interf4

[component]
footer //Adding "component" to force diagram to be a **component diagram**//
@enduml

Exemple de base

Basic example

Les liens entre les éléments sont établis à l'aide de combinaisons de symboles de lignes pointillées (..), de lignes droites (--) et de flèches (-->)

@startuml

DataAccess - [First Component]
[First Component] ..> HTTP : use

@enduml

Links between elements are made using combinations of dotted line (..), straight line (--), and arrows (-->) symbols.

@startuml

DataAccess - [First Component]
[First Component] ..> HTTP : use

@enduml

Utilisation des notes

Using notes

Vous pouvez utiliser les mots-clés note left of , note right of, note top of , note bottom of pour définir des notes relatives à un seul objet.

Une note peut également être définie seule avec les mots-clés note , puis liée à d'autres objets à l'aide du symbole ..

@startuml

interface "Data Access" as DA

DA - [First Component]
[First Component] ..> HTTP : use

note left of HTTP : Web Service only

note right of [First Component]
  A note can also
  be on several lines
end note

@enduml

WARNING
 This translation need to be updated. 
WARNING

You can use the note left of , note right of , note top of , note bottom of keywords to define notes related to a single object.

@startuml
[Component] as C

note top of C: A top note

note bottom of C
  A bottom note can also
  be on several lines
end note

note left of C
  A left note can also
  be on several lines
end note

note right of C: A right note
@enduml

A note can be also defined alone with the note keywords, then linked to other objects using the .. symbol or whatever arrow symbol (-, --, ...).

@startuml
[Component] as C

note as N
  A floating note can also
  be on several lines
end note

C .. N
@enduml

Another note example:

@startuml

interface "Data Access" as DA

DA - [First Component]
[First Component] ..> HTTP : use

note left of HTTP : Web Service only

note right of [First Component]
  A note can also
  be on several lines
end note

@enduml

Regroupement de composants

Grouping Components

Vous pouvez utiliser plusieurs mots-clés pour regrouper des composants et des interfaces
  • package
  • node
  • folder
  • frame
  • cloud
  • database

@startuml

package "Some Group" {
  HTTP - [First Component]
  [Another Component]
}

node "Other Groups" {
  FTP - [Second Component]
  [First Component] --> FTP
}

cloud {
  [Example 1]
}


database "MySql" {
  folder "This is my folder" {
    [Folder 3]
  }
  frame "Foo" {
    [Frame 4]
  }
}


[Another Component] --> [Example 1]
[Example 1] --> [Folder 3]
[Folder 3] --> [Frame 4]

@enduml

You can use several keywords to group components and interfaces together:
  • package
  • node
  • folder
  • frame
  • cloud
  • database

@startuml

package "Some Group" {
  HTTP - [First Component]
  [Another Component]
}

node "Other Groups" {
  FTP - [Second Component]
  [First Component] --> FTP
}

cloud {
  [Example 1]
}


database "MySql" {
  folder "This is my folder" {
    [Folder 3]
  }
  frame "Foo" {
    [Frame 4]
  }
}


[Another Component] --> [Example 1]
[Example 1] --> [Folder 3]
[Folder 3] --> [Frame 4]

@enduml

Changement de direction des flèches

Changing arrows direction

Par défaut, les liens entre les classes ont deux tirets -- et sont orientés verticalement. Il est possible d'utiliser un lien horizontal en mettant un seul tiret (ou point) comme ceci

@startuml
[Component] --> Interface1
[Component] -> Interface2
@enduml

Vous pouvez également changer de direction en inversant le lien :

@startuml
Interface1 <-- [Component]
Interface2 <- [Component]
@enduml

Il est également possible de changer la direction de la flèche en ajoutant les mots-clés left, right, up ou down à l'intérieur de la flèche

@startuml
[Component] -left-> left
[Component] -right-> right
[Component] -up-> up
[Component] -down-> down
@enduml

Vous pouvez raccourcir la flèche en utilisant uniquement le premier caractère de la direction (par exemple, -d- au lieu de -down- ) ou les deux premiers caractères (-do-).

Veuillez noter que vous ne devez pas abuser de cette fonctionnalité : Graphviz donne généralement de bons résultats sans modification.

Et avec le paramètre left to right direction paramètre

@startuml
left to right direction
[Component] -left-> left
[Component] -right-> right
[Component] -up-> up
[Component] -down-> down
@enduml

By default, links between classes have two dashes -- and are vertically oriented. It is possible to use horizontal link by putting a single dash (or dot) like this:

@startuml
[Component] --> Interface1
[Component] -> Interface2
@enduml

You can also change directions by reversing the link:

@startuml
Interface1 <-- [Component]
Interface2 <- [Component]
@enduml

It is also possible to change arrow direction by adding left, right, up or down keywords inside the arrow:

@startuml
[Component] -left-> left
[Component] -right-> right
[Component] -up-> up
[Component] -down-> down
@enduml

You can shorten the arrow by using only the first character of the direction (for example, -d- instead of -down-) or the two first characters (-do-).

Please note that you should not abuse this functionality : Graphviz gives usually good results without tweaking.

And with the left to right direction parameter:

@startuml
left to right direction
[Component] -left-> left
[Component] -right-> right
[Component] -up-> up
[Component] -down-> down
@enduml

Utiliser la notation UML2

Use UML2 notation

Par défaut (à partir de la version v1.2020.13-14), la notation UML2 est utilisée.

@startuml

interface "Data Access" as DA

DA - [First Component]

@enduml

By default (from v1.2020.13-14), UML2 notation is used.

@startuml

interface "Data Access" as DA

DA - [First Component]

Utiliser la notation UML1

Use UML1 notation

La commande skinparam componentStyle uml1 est utilisée pour passer à la notation UML1

@startuml
skinparam componentStyle uml1

interface "Data Access" as DA

DA - [First Component]
[First Component] ..> HTTP : use

@enduml

The skinparam componentStyle uml1 command is used to switch to UML1 notation.

@startuml
skinparam componentStyle uml1

interface "Data Access" as DA

DA - [First Component]
[First Component] ..> HTTP : use

@enduml

Utiliser le style rectangle (supprime toute notation UML)

Use rectangle notation (remove UML notation)

La commande skinparam componentStyle rectangle est utilisée pour changer vers le style rectangle (sans aucune notation UML).

@startuml
skinparam componentStyle rectangle

interface "Data Access" as DA

DA - [First Component]
[First Component] ..> HTTP : use

@enduml

The skinparam componentStyle rectangle command is used to switch to rectangle notation (without any UML notation).

@startuml
skinparam componentStyle rectangle

interface "Data Access" as DA

DA - [First Component]
[First Component] ..> HTTP : use

@enduml

Description longue

Long description

Il est possible de mettre un long texte sur plusieurs lignes en utilisant des crochets.

@startuml
component comp1 [
This component
has a long comment
on several lines
]
@enduml

It is possible to put description on several lines using square brackets.

@startuml
component comp1 [
This component
has a long comment
on several lines
]
@enduml

Couleurs individuelles

Individual colors

Vous pouvez spécifier une couleur après la définition du composant

@startuml
component  [Web Server] #Yellow
@enduml

You can specify a color after component definition.

@startuml
component  [Web Server] #Yellow

}


rectangle " End to End\nbusiness process" <<$businessProcess>> {
 rectangle "inner process 1" <<$businessProcess>> as src
 rectangle "inner process 2" <<$businessProcess>> as tgt
 src -> tgt
