Componentes

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.

🎉 Copied! 

@startuml

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

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.

🎉 Copied! 

@startuml

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

Agrupando componentes

Puedes usar varias palabras reservadas para agrupar componentes e interfaces juntos:
  • package
  • node
  • folder
  • frame
  • cloud
  • database

🎉 Copied! 

@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]

Cambiando la dirección de las flechas

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:

🎉 Copied! 

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

Puedes también cambiar direcciones invirtiendo el link:

🎉 Copied! 

@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:

🎉 Copied! 

@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.
