    • recorderInitialized

      default void recorderInitialized(FlightRecorder recorder)
      Receives notification when Flight Recorder is initialized.

      This method is also be invoked when a listener is added to an already initialized Flight Recorder.

      This method allows clients to implement their own initialization mechanism that is executed before a FlightRecorder instance is returned by FlightRecorder.getFlightRecorder().

      Implementation Requirements:
      The default implementation of this method is empty.
      Implementation Note:
      This method should return as soon as possible, to avoid blocking initialization of Flight Recorder. To avoid deadlocks or unexpected behavior, this method should not call FlightRecorder.getFlightRecorder() or start new recordings.
      Parameters:
      recorder - Flight Recorder instance, not null

      Implementation Note:
