Method Detail

deleteEvent

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

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

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

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

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

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

void complete()

Completes the stream.

onCompletedByServer

void onCompletedByServer(Consumer<Throwable> onCompleted)

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

Parameters:

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