API Changes

• Project API
  • ProjectController now executes all methods synchronously, protected by an internal lock. The openProject(), saveProject() no longer return a Runnable.
  • Addition of a ProjectListener to receive events from ProjectController.
  • New ProjectController.openNewWorkspace() to simplify usage.
  • New WorkspaceMetaData object in Workspace to manage description.
  • Creation of new SPI classes: Controller and Model to facilitate workspace model creation. It can replace usage of WorkspaceListener to handle model creation and maintenance.
  • Removal of org.gephi.project.spi.ProjectPropertiesUI as it had no clear purpose.
  • The ProjectController.startup() method was removed as it wasn't used.
  • Deprecation of ProjectInformation. Relevant methods have been ported to Project.
  • Also deprecation of WorkspaceInformation. Relevant methods have been ported to Workspace.
  • Finally, deprecation of WorkspaceProvider. Relevant methods were ported to Project.
  • The duplication of workspaces is now managed through existing persistence providers. Therefore the WorkspaceDuplicateProvider SPI has been removed.
• LongTask API
  • The LongTaskExecutor now has execute methods that also support Callable in addition of Runnable.
• Preview API
  • The PDFTarget interface now gives access to the PDFBox objects as it has been migrated from iText to Apache PDFBox. All Renderer implementation need to adapt the PDF rendering accordingly.
  • A setGlobalCanvasSize(boolean) method was added to the PreviewController to control whether the full or filtered (default) graph is used when calculating canvas size.
• Import API
  • The ContainerLoader now has a setMetadata() method to provide graph metadata.
