    • migrate070To080

      void migrate070To080(Diagram diagram)
      Moves fonts which, in 0.7.0, were aggregated by AbstractText and Style to the diagram which aggregates fonts centrally as of 0.8.0. Possibly modifies the diagram. Has to be called from within a write transaction. It is assumed that there is only one diagram stored in the underlying resource.
      Parameters:
      diagram - the diagram to be migrated

    • shouldMigrate070To080

      boolean shouldMigrate070To080(Diagram diagram)
      Checks if fonts are set on graphical elements while not being managed by the diagram. It is assumed that there is only one diagram stored in the underlying resource.
      Parameters:
      diagram - the diagram under consideration
      Returns:
      true if the diagram should be migrated, false otherwise

    • migrate080To090

      void migrate080To090(Diagram d)
      Sets all filled attributes of abstract text instances to false. Prior to 0.9 the filled attribute was not evaluated by the rendering engine. A actual value of TRUE was an effective FALSE. Has to be called from within a write transaction. It is assumed that there is only one diagram stored in the underlying resource.
      Parameters:
      d - the diagram to be migrated
      Since:
      0.9

    • shouldMigrate080To090

      boolean shouldMigrate080To090(Diagram d)
      Checks if a version number is present. Prior to 0.9 no version number was given to the diagram.
      Parameters:
      d - the diagram under consideration
      Returns:
      true if the diagram should be migrated
      Since:
      0.9
