La sintaxis anterior utilizada para los diagramas de actividad presentaba varias limitaciones y problemas de mantenimiento. Reconociendo estos inconvenientes, hemos introducido una sintaxis e implementación totalmente renovadas que no sólo son fáciles de usar, sino también más estables.
Ventajas de la nueva sintaxis
- Sin dependencia de Graphviz: Al igual que con los diagramas de secuencia, la nueva sintaxis elimina la necesidad de instalar Graphviz, simplificando así el proceso de configuración.
- Facilidad de mantenimiento: La* naturaleza intuitiva de la nueva sintaxis significa que es más fácil de manejar y mantener sus diagramas.
Transición a la Nueva Sintaxis
Mientras que continuaremos apoyando la sintaxis antigua para mantener la compatibilidad, animamos a los usuarios a migrar a la nueva sintaxis para aprovechar las características mejoradas y los beneficios que ofrece.
Haga el cambio hoy y experimente un proceso de diagramación más ágil y eficiente con la nueva sintaxis de diagrama de actividad.
Las etiquetas de las actividades inician con un dos puntos (:) y terminan con un punto y coma (;).
Se puede aplicar formato a un texto usando sintaxis de WikiCreole.
Están implícitamente enlazados en el orden de su definición.
