There are 2 overloading methods to change the flow event.
public void changeEvent(String nextEventName, KeyedCollection input, KeyedCollection output) throws Exception
public JSONObject changeEvent(String nextEventName, HashMap<String, Object> input) throws Exception
▪ They have almost the identical function, change the current flow event < nextEventName >.
▪ You can use KeyedCollection as the input and output data.
▪ You can also use HashMap<String, Object> as the input data in the application that is NOT aware of UDTT Context Data. Then you can access the output data in JSON format with getJsonData().
