create

public static org.openjdk.jmc.flightrecorder.internal.IChunkLoader create(Chunk input,
                                                                          LoaderContext context)

Throws:

IOException

CouldNotLoadRecordingException

getInfo

public static org.openjdk.jmc.flightrecorder.internal.ChunkInfo getInfo(Chunk input,
                                                                        long position)

Throws:

IOException

CouldNotLoadRecordingException

getTimestamp

public long getTimestamp()

Specified by:

getTimestamp in interface org.openjdk.jmc.flightrecorder.internal.IChunkLoader

Returns:

The chunk timestamp. The unit is not specified, it might be milliseconds or nanoseconds since 1970, but the important thing is that it is unique for every chunk in a recording.
