Définitions des participants

Declaring element or participant

Les participants sont déclarés à l'aide des mots-clé consise ou robust, en fonction de la façon dont vous souhaitez les dessiner.

  • concise: A simplified signal designed to show the movement of data (great for messages).
  • robust: A complex line signal designed to show the transition from one state to another (can have many states).
  • clock: A 'clocked' signal that repeatedly transitions from high to low
  • binary: A specific signal restricted to only 2 states (binary).

Les changements d'état sont notifiés avec la notation @ et le verbe is.

You declare participant using the following keywords, depending on how you want them to be drawn.

Keyword Description
concise A simplified signal designed to show the movement of data (great for messages)
robust A complex line signal designed to show the transition from one state to another (can have many states)
clock A clocked signal that repeatedly transitions from high to low, with a period, and an optional pulse and offset
binary A specific signal restricted to only 2 states (binary)

You define state change using the @ notation, and the is verb.

Horloge et signaux binaires

Binary and Clock

It's also possible to have binary and clock signal, using the following keywords:

  • binary
  • clock

@startuml
clock clk with period 1
binary "Enable" as EN

@0
EN is low

@5
EN is high

@10

Ajout de messages

Adding message

Vous pouvez rajouter des messages à l'aide de la syntaxe suivante.

@startuml

concise "Web User" as WU

@0
WU is Idle
WB is Idle

@100
WU -> WB : URL
WU is Waiting

@enduml

You can add message using the following syntax.

@startuml

Référence relative de temps

Relative time

Avec la notation @, il est possible d'utiliser une notation relative du temps.

Points d'ancrage

Anchor Points

Au lieu d'utiliser le temps absolu ou relatif sur un temps absolu, vous pouvez définir un temps comme point d'ancrage en utilisant le mot clé as et en commençant le nom par un :

@XX as :<anchor point name>

@startuml
clock clk with period 1
binary "enable" as EN
concise "dataBus" as db

@0 as :start
@5 as :en_high 
@10 as :en_low
@:en_high-2 as :en_highMinus2

@:start
EN is low
db is "0x0000"

@:en_high
EN is high

@:en_low
EN is low

@:en_highMinus2
db is "0xf23a"

@:en_high+6
db is "0x0000"
@enduml

Instead of using absolute or relative time on an absolute time you can define a time as an anchor point by using the as keyword and starting the name with a :.

@XX as :<anchor point name>

@startuml
clock clk with period 1
binary "enable" as EN
concise "dataBus" as db

@0 as :start
@5 as :en_high 
@10 as :en_low
@:en_high-2 as :en_highMinus2

@:start
EN is low
db is "0x0000"

@:en_high
EN is high

@:en_low
EN is low

@:en_highMinus2
db is "0xf23a"

@:en_high+6
db is "0x0000"

Définition participant par participant

Participant oriented

Plutôt que de déclarer le diagramme dans l'ordre chronologique, il est possible de le définir participant par participant.

concise "Web User" as WU

@WB
0 is idle
+200 is Proc.
+100 is Waiting

@WU
