iterate over trigger newmap

... Trigger.newmap.keyset()]) Trigger.newMap.keySet() is a Set. TriggerWorker class [This is the worker class for trigger. We don’t really need to access every account in this trigger context, but only a subset—the accounts without opportunities. The trigger you've added iterates over all records that are part of the trigger context—the for loop iterates over Trigger.New. It should continue to update every time the “Contact_Exist__c” field on any Cont… Unless the Name field of the NewMember__c object contains an Account Id, this query will return no data. Similarly, if you have multiple loops over each item the trigger is operating on, the list returned by Trigger.new may be the better bet. Thanks for the reply, but I think, I needed to know how to loop through the sorted array to access a key, say count for example. 5. Keeping trigger logic for each object in a single place avoids problems where multiple triggers are in contention with each other and makes it easier to debug. Further considerations: If you recall from the documentation along with the trigger.new property there are other properties that we make use of here, in particular: trigger.oldMap and trigger.newMap. For this, we need to use Trigger.New and Trigger.Old to get a list of records in trigger. The patterns enforce a logical sequence to the trigger code and in turn help to keep code tidy and more maintainable. Thanks. 3. And if we are using any DML operation inside trigger, we should use Database.Insert or Database.Update to be able to control transaction rollback. The trigger you’ve added iterates over all records that are part of the trigger context—the for loop iterates over Trigger.New. We don't really need to access every account in this trigger context, but only a subset—the accounts without opportunities. According to the docs, Trigger.new returns a list, which are ordered, and Trigger.newMap returns a map – which are unordered. However, the loop in this trigger could be more efficient. Each and every trigger just call "executeTrigger()" method of this worker class]. So the first loop of this trigger is to go through the list of accounts and identify which accounts had an address change. 4. TriggerFactory class [Factory of Concrete Trigger Handler classes]. To get a map of records, Trigger.NewMap and Trigger.OldMap can be used. – user12236299 Jan 30 at 6:26 add a comment | Your Answer The docs specifically state you should not rely on the ordering of a map's elements. Otherwise, you'd have to loop over all the elements in Trigger.new and look for a matching ID. Trigger.newMap dont work for before insert while Trigger.New works fine for holding all Ids of records while inserting. Create an interface ITrigger as following public interface ITrigger { /** * bulkBefore * * This method is called prior to execution of a BEFORE trigger. TriggerHandler class [An abstract class where all trigger related operations have been structured as a template]. According to the docs, Trigger.new returns a list, which are ordered, and Trigger.newMap returns a map - which are unordered. Note : Trigger.newMap dont work for before insert while Trigger.New works fine for holding all Ids of records while inserting. Given there is one contact, then the “Contact_Exist__c” field on the Account should display from the Contact. You probably mean to be iterating over Trigger.new and checking for records whose Record Type Id matches this one. However, the loop in this trigger could be more efficient.
