Method Detail

events

public Stream<AccessEvent> events()

Description copied from interface: TraceReader

Creates a stream that lazily reads the trace source.

If timely disposal of underlying resources is required, the try-with-resources construct should be used to ensure that the stream's close method is invoked after the stream operations are completed.

Returns:

a lazy stream of cache events

readEvent

protected abstract AccessEvent readEvent(DataInputStream input)
                                  throws IOException

Returns the next event from the input stream.

Throws:

IOException
