Throws:

CouldNotLoadRecordingException

IOException

loadStream

public static EventArray[] loadStream(InputStream stream,
                                      List<? extends IParserExtension> extensions,
                                      boolean hideExperimentals,

                                      IOException

Read events from an input stream of JFR data.

Parameters:

stream - input stream

extensions - the extensions to use when parsing the data

hideExperimentals - if true, then events of types marked as experimental will be ignored when reading the data

Returns:

an array of EventArrays (one event type per EventArray)

Throws:

CouldNotLoadRecordingException
