Manage Order of Trigger Execution in Salesforce for Object

Hi guys,

Note: Handle the trigger order of execution:


If any Case when you required to write 4 triggers on different - different events but on same object
then don't write 4 trigger for same.
Suppose you have 4 trigger on Account Object.

1- AccTrigger1.trigger
2- AccTrigger2.trigger
3- AccTrigger3.trigger
4- AccTrigger4.trigger



Solution is mention as below

STEP 1- Create only one trigger for one object(Account) like- In above case instead of having 5 triggers on 

STEP 2- Create only 1 trigger that is AccountTrigger.trigger on Account Object.

// Create Trigger as Mention Below

trigger AccountTrigger on Account (after insert, after update, before delete, before insert, before update) 
{
    AccortunityTriggerHandler triggerHandler = new AccortunityTriggerHandler(Trigger.isExecuting,Trigger.size);
   
    if(Trigger.isBefore && Trigger.isInsert){
        triggerHandler.OnBeforeInsert(trigger.new, trigger.NewMap);
    }
   
    if(Trigger.isAfter && Trigger.isInsert){
        triggerHandler.OnAfterInsert(trigger.new, trigger.NewMap);
    }
   
    if(Trigger.isBefore && Trigger.isUpdate){       
        triggerHandler.OnBeforeUpdate(trigger.new, trigger.NewMap, Trigger.oldMap);
    }
   
    if(Trigger.isAfter && Trigger.isUpdate){
        triggerHandler.OnAfterUpdate(trigger.new, trigger.NewMap, Trigger.oldMap);
    }
        
    if(Trigger.isBefore && Trigger.isDelete){       
        triggerHandler.OnBeforeDelete(trigger.Old, Trigger.oldMap);
    }
   
    if(Trigger.isAfter && Trigger.isDelete){
        triggerHandler.OnAfterDelete(trigger.Old, Trigger.oldMap);
    }
}

// end of trigger

// Create a new Class and handle all events in the class with creating method

STEP 3- In the trigger I have called different Methods for Different DML Event and these methods are declared in a class "AccortunityTriggerHandler.cls". the code of this class is like-

public class AccortunityTriggerHandler {
    
    private boolean m_isExecuting = True;
    private integer BatchSize = 0;
    private final static boolean ISUPDATE_TRUE = true;
    private final static boolean ISUPDATE_FALSE = false;
    
    public AccortunityTriggerHandler(boolean isExecuting, integer size)
    {
        m_isExecuting = isExecuting;
        BatchSize = size;
    }
    public void onBeforeInsert(list<Account> triggerNew, map<id,Account> triggerNewMap)
    {
        // call Before Insert Method
    }
        
    public void OnAfterInsert(list<Account> triggerNew, map<id,Account> triggerNewMap)
    {
        // call After Insert Method
//MehtodNameAfterInsert
    }
    
    public void OnBeforeUpdate(list<Account> triggerNew, map<id,Account> triggerNewMap, map<id,Account> triggerOldMap)
    {
       // call Before update Method
    }
    
    public void OnAfterUpdate(list<Account> triggerNew, map<id,Account> triggerNewMap, map<id,Account> triggerOldMap)
    {
        // call After update Method
    }
    
    public void OnBeforeDelete(list<Account> triggerOld, map<id,Account> triggerOldMap)
    {
        // call Before Delete Method
    }
    
    public void OnAfterDelete(list<Account> triggerOld, map<id,Account> triggerOldMap)
    {
        // call After Delete Method
    }


private void MehtodNameAfterInsert(list<Account> triggerNew,map<id,Account> triggerNewMap)
{
  // write logic here
}
 
// create more method as per your requirement
}
