Let's have few examples.

Componentes

Components

Los componentes deberían ser encerrados entre corchetes [].

También puedes usar la palabra reservada component para definir un componente. Y puedes definir un alias, usando la palabra reservada as. Este alias será usado más adelante, cuando definamos relaciones.

@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

Puedes definir una interfaz usando el símbolo () (porque esto luce como un circulo).

Puedes usar también la palabra reservada interface para definir una interfaz. Y puedes definir un alias, usando la palabra reservada as. Este alias sera usado luego, definiendo las relaciones.

Nosotros veremos mas adelante que la definición de interfaz es opcional.

@startuml

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

@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

Ejemplos basicos

Basic example

Los links entre los elementos se hacen usando la combinación de símbolos de linea de puntos (..), linea recta (--), y flechas (-->)

@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

Usando notas

Using notes

Puedes usar el note left of , note right of , note top of , note bottom of Las palabras reservadas para definir notas relacionadas a un objeto simple.

Una nota puede ser definida sola usando la plabra reservada note, luego linkea a otro objeto usando el símbolo ...

@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

Agrupando componentes

Grouping Components

Puedes usar varias palabras reservadas para agrupar componentes e interfaces juntos:
  • 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

Cambiando la dirección de las flechas

Changing arrows direction

Por defecto los links entre clases tienen dos guiones --y son orientados verticalmente. Puedes usar la orientacion horizontal para un link poniendo un guion (o punto) como en el siguiente ejemplo:

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

Puedes también cambiar direcciones invirtiendo el link:

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

También es posible cambiar la dirección de las flechas agregando la palabra reservada left, right, up o down dentro de la flecha:

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

Puedes acortar la flecha usando el primer caracter (por ejemplo, -d- en lugar de -down-) o los dos primeros caracteres (-do-).

Por favor nota que no puedes abuzar de esta funcionalidad Graphviz que usualmente otorga buenos resultados sin ajustes.

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

Use UML2 notation

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

@startuml

interface "Data Access" as DA

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

@enduml

Utiliza la notación UML1

Use UML1 notation

El comando skinparam componentStyle uml1 es usado para cambiar hacia la notación 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

Use rectangle notation (remove UML notation)

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

Long description

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

Colores individuales

Individual colors

Puedes especificar un color despues de la definición del componente.

@startuml
component  [Web Server] #Yellow
@enduml

You can specify a color after component definition.

@startuml
component  [Web Server] #Yellow
@enduml

Using Sprite in Stereotype

You can use sprites within stereotype components.

@startuml
sprite $businessProcess [16x16/16] {
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFF0FFFFF
FFFFFFFFFF00FFFF
FF00000000000FFF
FF000000000000FF
FF00000000000FFF
FFFFFFFFFF00FFFF
FFFFFFFFFF0FFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
FFFFFFFFFFFFFFFF
}


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

Personalización (Skinparam)

Skinparam

Puedes usar el comando skinparam para cambiar los colores y las fuentes de los dibujos

Puedes usar este comando:

Puedes definir colores y fuentes específicas para interfaces y componentes estereotipados.

@startuml

skinparam interface {
  backgroundColor RosyBrown
  borderColor orange
}

skinparam component {
  FontSize 13
  BackgroundColor<<Apache>> Red
  BorderColor<<Apache>> #FF6655
  FontName Courier
  BorderColor black
  BackgroundColor gold
  ArrowFontName Impact
  ArrowColor #FF6655
  ArrowFontColor #777777
}

() "Data Access" as DA

DA - [First Component]
[First Component] ..> () HTTP : use
HTTP - [Web Server] << Apache >>

@enduml

@startuml
[AA] <<static lib>>
[BB] <<shared lib>>
[CC] <<static lib>>

node node1
node node2 <<shared node>>
database Production

skinparam component {
    backgroundColor<<static lib>> DarkKhaki
    backgroundColor<<shared lib>> Green
}

skinparam node {

WARNING

You can use the skinparam command to change colors and fonts for the drawing.

You can use this command :

You can define specific color and fonts for stereotyped components and interfaces.

@startuml

skinparam interface {
  backgroundColor RosyBrown
  borderColor orange
}

skinparam component {

@enduml

Specific SkinParameter

componentStyle

  • By default (or with skinparam componentStyle uml2), you have an icon for component

@startuml
skinparam BackgroundColor transparent
skinparam componentStyle uml2
component A {
   component "A.1" {
}
   component A.44 {
      [A4.1]
}
   component "A.2"
   [A.3]
   component A.5 [
A.5] 
   component A.6 [
]
}
[a]->[b]
@enduml

  • If you want to suppress it, and to have only the rectangle, you can use skinparam componentStyle rectangle

@startuml
skinparam BackgroundColor transparent
skinparam componentStyle rectangle
component A {
   component "A.1" {
}
   component A.44 {
      [A4.1]
}
   component "A.2"
   [A.3]
   component A.5 [
A.5] 
   component A.6 [
]
}
[a]->[b]
@enduml

Hide or Remove unlinked component

By default, all components are displayed:

@startuml
component C1
component C2
component C3
C1 -- C2
@enduml

But you can:
  • hide @unlinked components:

@startuml
component C1
component C2
component C3
C1 -- C2

hide @unlinked
@enduml

  • or remove @unlinked components:

@startuml
component C1
component C2
component C3
C1 -- C2

remove @unlinked
@enduml

[Ref. QA-11052]

Hide, Remove or Restore tagged component or wildcard

You can put $tags (using $) on components, then remove, hide or restore components either individually or by tags.

By default, all components are displayed:

@startuml
component C1 $tag13
component C2
component C3 $tag13
C1 -- C2
@enduml

But you can:
  • hide $tag13 components:

@startuml
component C1 $tag13
component C2
component C3 $tag13
C1 -- C2

hide $tag13
@enduml

  • or remove $tag13 components:

@startuml
component C1 $tag13
component C2
component C3 $tag13
C1 -- C2

remove $tag13
@enduml

  • or remove $tag13 and restore $tag1 components:

@startuml
component C1 $tag13 $tag1
component C2
component C3 $tag13
C1 -- C2

remove $tag13
restore $tag1
@enduml

  • or remove * and restore $tag1 components:

@startuml
component C1 $tag13 $tag1
component C2
component C3 $tag13
C1 -- C2

remove *
restore $tag1
@enduml
