Method Detail

recorderInitialized back to summary

recorderInitialized	back to summary
public 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 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. Implementation Specification The default implementation of this method is empty. Parameters recorder:FlightRecorder Flight Recorder instance, not `null` See Also `FlightRecorder#addListener(FlightRecorderListener)`
