Query Parameters (19 parameters): Name Description Default Type atomix (common) The Atomix instance to use Atomix broadcastType (common) The broadcast type. ALL BroadcastType channelName (common) The messaging channel name String configurationUri (common) The Atomix configuration uri. String defaultAction (common) The default action. DIRECT Action memberName (common) The Atomix Group member name String nodes (common) The address of the nodes composing the cluster. String resultHeader (common) The header that wil carry the result.
