GrpcTransformationStream

public GrpcTransformationStream(String transformationId,
                                io.grpc.stub.StreamObserver<TransformRequest> requestStreamObserver,
                                Consumer<Consumer<Long>> ackListenerRegistration,

Method Detail

deleteEvent

public CompletableFuture<Void> deleteEvent(long token,
                                           long sequence)

Description copied from interface: EventTransformationService.TransformationStream

Registers the request to delete the event with the specified token.

Specified by:

deleteEvent in interface EventTransformationService.TransformationStream

Parameters:

token - the token of the event to be deleted

sequence - the expected last sequence of the transformation, used to check that no change request before this one has been lost

Returns:

a CompletableFuture that completes when the request has been received by Axon Server.

replaceEvent

public CompletableFuture<Void> replaceEvent(long token,
                                            Event event,
                                            long sequence)

Description copied from interface: EventTransformationService.TransformationStream

Registers the request to replace the event with the specified token.

Specified by:

replaceEvent in interface EventTransformationService.TransformationStream

Parameters:

token - the token of the event to be replaced

event - the new version of the event, to be used as a replacement for the original one

sequence - the expected last sequence of the transformation, used to check that no change request before this one has been lost

Returns:

a CompletableFuture that completes when the request has been received by Axon Server.

complete

public void complete()

Description copied from interface: EventTransformationService.TransformationStream

Completes the stream.

Specified by:

complete in interface EventTransformationService.TransformationStream

onCompletedByServer

public void onCompletedByServer(Consumer<Throwable> onCompleted)

Description copied from interface: EventTransformationService.TransformationStream

Resister a callback function that is invoked when the stream is completed by Axon Server.

Specified by:

onCompletedByServer in interface EventTransformationService.TransformationStream

Parameters:

onCompleted - the callback function invoked when the stream is completed by Axon Server.
