sendSynchronously

protected void sendSynchronously(DefaultBroadcastService.MethodWrapper methodWrapper,
                                 RawMessage message)

Sends a message synchronously.

Parameters:

methodWrapper - the method wrapper

message - the message to send

sendAsnychronously

protected void sendAsnychronously(DefaultBroadcastService.MethodWrapper methodWrapper,
                                  RawMessage message,

Sends a message using a executor service. In case the service is rejecting the message this method blocks and tries to send the message again until the configured wait timeout has been reached.

Parameters:

methodWrapper - the method wrapper

message - the message

currentTenant - the current tenant to be used when sending

executorService - the executor service

Throws:

java.util.concurrent.RejectedExecutionException

accept

Specified by:

accept in interface BroadcastService

Parameters:

message - the message to check

Returns:

true if the message is being accepted
