      public BaseCompareAction()

  • Method Details

    • run

      public final void run(IAction action)
      Description copied from interface: IActionDelegate
      Performs this action.

      This method is called by the proxy action when the action has been triggered. Implement this method to do the actual work.

      Note: If the action delegate also implements IActionDelegate2, then this method is not invoked but instead the runWithEvent(IAction, Event) method is called.

      Specified by:
      run in interface IActionDelegate
      Parameters:
      action - the action proxy that handles the presentation portion of the action

    • selectionChanged

      public final void selectionChanged(IAction action, ISelection selection)
      Description copied from interface: IActionDelegate
      Notifies this action delegate that the selection in the workbench has changed.

      Implementers can use this opportunity to change the availability of the action or to modify other presentation properties.

      When the selection changes, the action enablement state is updated based on the criteria specified in the plugin.xml file. Then the delegate is notified of the selection change regardless of whether the enablement criteria in the plugin.xml file is met.

      Specified by:
      selectionChanged in interface IActionDelegate
      Parameters:
      action - the action proxy that handles presentation portion of the action
      selection - the current selection, or null if there is no selection.

    • isEnabled

      protected boolean isEnabled(ISelection selection)

    • run

      protected abstract void run(ISelection selection)
