public class ChecksumEventStream
extends AbstractObjectStream<Event>

A Checksum-based event stream implementation. Computes the checksum while consuming the event stream. By default, this implementation will use CRC32C for checksum calculations as it can use of CPU-specific acceleration instructions at runtime.

ChecksumEventStream

public ChecksumEventStream(ObjectStream<Event> eventStream)

Initializes an ChecksumEventStream.

Parameter:

eventStream - The ObjectStream that provides the Event samples.

Methodendetails

read

public Event read()
           throws IOException

Beschreibung aus Schnittstelle kopiert: ObjectStream

Returns the next ObjectStream object. Calling this method repeatedly until it returns null will return each object from the underlying source exactly once.

Angegeben von:

read in Schnittstelle ObjectStream<Event>

Setzt außer Kraft:

read in Klasse AbstractObjectStream<Event>

Gibt zurück:

The next object or null to signal that the stream is exhausted.

Löst aus:

IOException - Thrown if there is an error during reading.

calculateChecksum

public long calculateChecksum()

Calculates and returns the (current) checksum.

Note: This should be called once the underlying stream has been (fully) consumed.

Gibt zurück:

The calculated checksum as long.
