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
