Example trigger BeforeInsertTrigger on Account (before insert) {
set<id> sid = new set<id>();
for(Account A :trigger.new){
sid.add(A.Id);
system.debug('sid :'+sid);
//This line of code would raise Null Pointer Exception becasue trigger.newMap dont work for before trigger.while Sid will Contain all Ids of records.
//If you are using after insert this trigger.newMap would return you the Objects Values in Acc.
Account Acc = trigger.newMap.get(A.Id);
system.debug('Acc :'+Acc);
}
}
Note : If you are setting event after insert then this will not raise error it will let you have all data with all Ids in Acc.
Account Acc = trigger.newMap.get(Acc.Id);
Now you have All record field value in Acc object.
Documentation reads
newMap A map of IDs to the new versions of the sObject records.
Note that this map is only available in before update, after insert, and after update triggers.
oldMap A map of IDs to the old versions of the sObject records.
Note that this map is only available in update and delete triggers.
