  • Method Details

    • read

      public boolean read()
      Deprecated.
      Starts the reader. This method is intended to be a blocking operation, i.e., it is assumed that reading has finished before this method returns. The method should indicate an error by the return value false. In asynchronous scenarios, the IPlugin.terminate(boolean) method can be used to initiate the termination of this method.
      Returns:
      true if reading was successful; false if an error occurred
    • terminate

      public void terminate(boolean error)
      Deprecated.
      Initiates a termination of the plugin. This method is only used by the framework and should not be called manually. Use the method AnalysisController.terminate(boolean) instead. After receiving this notification, the plugin should terminate any running methods, e.g., read for readers.
      Parameters:
      error - Determines whether the plugin is terminated due to an error or not.
    • getCurrentConfiguration

      public Configuration getCurrentConfiguration()
      Deprecated.
      This method should deliver a Configuration object containing the current configuration of this instance. In other words: The constructor should be able to use the given object to initialize a new instance of this class with the same intern properties.
