.. py:class:: FFTOnlineSingleChannel(kafka_kwargs, fft_window=5, kafka_topic='pmudata', channel_selection_idx=None, *args, **kwargs)

   Bases: :py:obj:`pswamp.app_templates.time_window_app.TimeWindowApp`


   General time window application template.

   New applications could be defined by inheriting from this template, and
   defining the "run_analysis" method. Similar to SnapshotApp, but has an
   internal time window storage. The length of the time window is determined by
   either of the arguments n_samples or window_length. If neither are
   specified, the size of the time window will grow indefinitely.


   TODO: Remove channel_selection and channel_selection_idx from arguments.

   :param io: Input/output object (normally connects to Kafka)
   :param eval_freq: How often the evaluation of the application should be run
                     (e.g., the part in "run_analysis")
   :param t_end: The application will stop running when this time is reached
                 (but can be restarted)
   :param t_start: The application will ask the io object (first argument) to
                   search for t_start when initializing.
   :param app_name: Name for the application.
   :param input_decoder: This determines how the input is read/decoded (if no
                         decoder is specified, a decoder for PMU data frames will be used.)
   :param decoder_kwargs: Kwargs for initalizing the "input_decoder".
   :param channel_selection: Argument for specifying channel subset.
   :param channel_selection_idx: Argument for specifying channel subset.
   :param n_samples: Determines the window length in samples.
   :param window_length: Determines the window length in seconds.
   :param report_status: If enabled, status messages will be emitted.
   :param io_kwargs: Any other kwargs will be forwarded to the io object.
