  Modifier and Type	Method and Description
  void	close() Closes the filters in a graph.
  Exception	getError() Returns the last exception that happened during an asynchronous run.

  boolean	isRunning() Check if background processing is happening
  void	run() Execute the graph in a background thread.
  void	setDoneCallback(GraphRunner.OnRunnerDoneListener listener) Set a callback to be called in the UI thread once the AsyncRunner completes running a graph, whether the completion is due to a stop() call or the filters running out of data to process.

  • AsyncRunner

    public AsyncRunner(FilterContext context,
               Class schedulerClass)

    Create a new asynchronous graph runner with the given filter context, and the given scheduler class. Must be created on the UI thread.

  • AsyncRunner

    public AsyncRunner(FilterContext context)

    Create a new asynchronous graph runner with the given filter context. Uses a default scheduler. Must be created on the UI thread.

• Method Detail

  • setDoneCallback

    public void setDoneCallback(GraphRunner.OnRunnerDoneListener listener)

    Set a callback to be called in the UI thread once the AsyncRunner completes running a graph, whether the completion is due to a stop() call or the filters running out of data to process.

    Specified by:

    setDoneCallback in class GraphRunner

  • setGraph

    public void setGraph(FilterGraph graph)

    Sets the graph to be run. Will call prepare() on graph. Cannot be called when a graph is already running.

  • getGraph

    public FilterGraph getGraph()

    Specified by:

    getGraph in class GraphRunner

  • run

    public void run()

    Execute the graph in a background thread.

    Specified by:

    run in class GraphRunner

  • stop

    public void stop()

    Stop graph execution. This is an asynchronous call; register a callback with setDoneCallback to be notified of when the background processing has been completed. Calling stop will close the filter graph.

    Specified by:

    stop in class GraphRunner

  • close

    public void close()

    Description copied from class: GraphRunner
    Closes the filters in a graph. Can only be called if the graph is not running.

    Specified by:

    close in class GraphRunner

  • isRunning

    public boolean isRunning()

    Check if background processing is happening

    Specified by:

    isRunning in class GraphRunner

  • getError

    public Exception getError()

    Description copied from class: GraphRunner
    Returns the last exception that happened during an asynchronous run. Returns null if there is nothing to report.

    Specified by:

    getError in class GraphRunner
