Step 6. Create an Apex Trigger for the Custom Object

Apex triggers enable you to perform custom actions before or after changes to the Salesforce records, such as insertions, updates, or deletions. The trigger code is stored as metadata under the custom object.

Based on the Salesforce environment that you use, perform one of the following tasks:

In Salesforce Classic, in the upper-right corner of the page, select your name, and click

Developer Console

In Lightning Experience, click the quick access menu ( The image shows the quick access menu.

), and then click

Developer Console

In the

Force.com Developer Console

window, under

File

, select

New

Apex Trigger

The

New Apex Trigger

window appears.

Enter a name for the trigger.

The name of the trigger should be the same as the API name of the custom object.

Select the custom object.

Click

Submit

In the trigger editor, enter a sample Apex code in the following format to create a trigger for the custom object:

trigger <TriggerName> on <CustomObject_API_Name> (after delete, after insert, after undelete,after update, before delete, before insert, before update)
{
DSE.API_CustomScoutClass cs =new DSE.API_CustomScoutClass('<CustomObjectName_API_Name>');
List<<CustomObject_API_Name>> <Variable1> = Trigger.new;
List<<CustomObject_API_Name>> <Variable2> = Trigger.old;
if (Trigger.isAfter)
{
if (<Variable1> != null)
<Variable1> = <Variable1>.deepClone(true, true, true);
if (<Variable2> != null)
<Variable2> = <Variable1>.deepClone(true, true, true);
}
cs.triggerSynchronize((List<SObject>) <Variable1>, (List<SObject>) <Variable2>, Trigger.isInsert, Trigger.isUpdate, Trigger.isUnDelete, Trigger.isBefore, Trigger.isAfter);
}

The Apex code sample uses the following parameters:

TriggerName

. Name of the trigger that you create.

CustomObject_API_Name

. API Name of the custom object for which you create the trigger.

Variable1

and

Variable2

. Variables used in the Apex code.

The following example Apex code creates a trigger named

EmployeeTrigger

for the custom object

Employee__c

trigger EmployeeTrigger on Employee__c (after delete, after insert, after undelete,
after update, before delete, before insert, before update)
{
DSE.API_CustomScoutClass cs = new DSE.API_CustomScoutClass('Employee__c');
List<Employee__c> newEmployee = Trigger.new;
List<Employee__c> oldEmployee = Trigger.old;
if (Trigger.isAfter) 
{ 
if (newEmployee != null) 
newEmployee = newEmployee.deepClone(true, true, true); 
if (oldEmployee != null) 
oldEmployee = oldEmployee.deepClone(true, true, true); 
} 
cs.triggerSynchronize((List<SObject>) newEmployee, (List<SObject>) oldEmployee, Trigger.isInsert, 
Trigger.isUpdate, Trigger.isDelete, Trigger.isUnDelete, Trigger.isBefore, Trigger.isAfter); 
}
