    • canExecute

      public final boolean canExecute(IContext context)
      Checks if this feature can be executed by delegating to the method canPrint(IPrintContext).
      Specified by:
      canExecute in interface IFeature
      Parameters:
      context - Context information for printing.
      Returns:
      true in case this print feature can be executed, false otherwise.

    • canPrint

      public boolean canPrint(IPrintContext context)
      Checks if this feature can execute. The default implementation simply returns true. Note that the Graphiti framework already checks the availability of printer in the print action that triggers this feature.
      Specified by:
      canPrint in interface IPrintFeature
      Parameters:
      context - Context information for printing.
      Returns:
      true in case this print feature can be executed, false otherwise.
    • prePrint

      public void prePrint(IPrintContext context)
      Hook method for executing stuff that needs to be done before actually printing a diagram. The default implementation does nothing.
      Specified by:
      prePrint in interface IPrintFeature
      Parameters:
      context - Context information for printing.
    • execute

      public final void execute(IContext context)
      Executes this print feature by sequentially calling prePrint(IPrintContext), IPrintFeature.print(IPrintContext) and postPrint(IPrintContext). This method will fail in case the passed context is no IPrintContext.
      Specified by:
      execute in interface IFeature
      Parameters:
      context - Context information for printing.
      See Also:
    • postPrint

      public void postPrint(IPrintContext context)
      Hook method for executing stuff that needs to be done after actually printing a diagram. The default implementation does nothing.
      Specified by:
      postPrint in interface IPrintFeature
      Parameters:
      context - Context information for printing.
    • hasDoneChanges

      public boolean hasDoneChanges()
      Hook method that reports if changes have been done while executing this feature. In case false is returned the feature will not appear in the undo stack. The default implementation simply returns false.
      Specified by:
      hasDoneChanges in interface IFeature
      Overrides:
      hasDoneChanges in class AbstractFeature
      Returns:
      true in case changes have been made, false otherwise.
