      public LaunchAppropriateUI(String[] args)
      Constructor.
      Parameters:
      args - command line arguments

  • Method Details

    • launch

      public void launch() throws Exception
      Launch the appropriate UI.
      Throws:
      Exception

    • getLaunchProperty

      private int getLaunchProperty()
      Find out what UI should be launched.

      First, we check the command line arguments to see if the first argument specifies the UI (e.g., "-textui", "-gui", etc.)

      If the first command line argument does not specify the UI, then we check the findbugs.launchUI system property to one of the following values:

      • -Dfindbugs.launchUI=textui for textui,
      • -Dfindbugs.launchUI=gui1 for the original swing gui,
      • -Dfindbugs.launchUI=gui2 for the new swing gui,
      • -Dfindbugs.launchUI=version for the ShowVersion main() method, or
      • -Dfindbugs.launchUI=help for the ShowHelp main() method.
      Any other value (or the absence of any value) will not change the default behavior, which is to launch the newer "gui2" on systems that support it.
      Returns:
      an integer UI code: TEXTUI, GUI1, GUI2, SHOW_VERSION, SHOW_HELP, or possibly another user-set int value

    • main

      public static void main(String[] args) throws Exception
      main() method. This is where execution of FindBugs (any UI) starts.
      Parameters:
      args - command line arguments
      Throws:
      Exception
