question: protected void handlePreResponse ( String ticket , JobsApiRequest apiRequest , AsyncResponse asyncResponse , Observable < PreResponse > preResponseObservable , boolean isEmpty ) { if ( isEmpty ) { handleJobResponse ( ticket , apiRequest , asyncResponse ) ; } else { handleResultsResponse ( preResponseObservable , asyncResponse , apiRequest ) ; } }
target:  If isEmpty is true, call the method to send the job payload to the user else call the method to send the job result to the user.
