Event Handlers - Bulk Orchestration

Question

I have the following code working in a post process event handler EventResult execute(), and need to "convert" it to work in BulkEventResult execute():
public EventResult execute(long processId, long eventId,
Orchestration orchestration) {
entityId = orchestration.getTarget().getEntityId();
params = new HashMap<String, Object>();
HashMap<String , Serializable> eventDataMap = new HashMap<String , Serializable>();
eventDataMap.putAll(orchestration.getInterEventData());
HashMap currentUserState = new HashMap();
HashMap newUserState = new HashMap();
currentUserState.putAll(((User) eventDataMap.get("CURRENT_USER")).getAttributes());
newUserState.putAll(((User) eventDataMap.get("NEW_USER_STATE")).getAttributes());
if(!((currentUserState.get("First Name")) == null)){
            // Take Action 1
        }else{
            // Take Action 2
EntityManager entityManager = Platform.getService(EntityManager.class);
try {
        entityManager.modifyEntity(orchestration.getTarget().getType(),entityId, params);
I understand from other posts that instead of User it is an array of Identity objects, but am having some trouble converting this into working code. Suggestions?

Answer 1

If you know the how to get all identities than there should not be problem.
// get new user state from bulk
private Object getNewUserStates(BulkOrchestration orchestration){
          logger.debug("UserAttrUpdateEvtHndler/getNewUserStates START");
          Object newUserStates = null;
          HashMap interEventData = orchestration.getInterEventData();
          if (interEventData != null)
               newUserStates = interEventData.get("NEW_USER_STATE");
          return newUserStates;
in execute method
//Get all Identities
Identity[] newUserStatesIdntArr = (Identity[])(Identity[])getNewUserStates(orchestration);
//get all user key.
int userKeylength = userKeys.length;
// Iterate now
for (int j = userKeylength; --j >= 0;) {
     try {
          Identity newUserState = newUserStatesIdntArr != null ? newUserStatesIdntArr[j] : null;
String firsName= newUserState.getAttribute("First Name")==null?"":(String)newUserState.getAttribute("First Name");
// do your operation here.
