Package io.iworkflow.core

Class UnregisteredClient

  • public class UnregisteredClient
extends java.lang.Object
    UntypedClient will let you invoke the APIs to iWF server without much type validation checks(workflow type, signalChannelName, etc). It's useful for calling Client APIs without workflow registry(which may require to have all the workflow dependencies)
