Solution: EventBus.publish() can be used to publish the platform events from Apex
Example: In this example,as soon as account is created, the platform event is fired using account trigger.
Platform Event: Account_Event__e
Account Trigger: AccountObjectTrigger
trigger AccountObjectTrigger on Account (after insert) {
List<Account_Event__e> lstPlatformEvent = new List<Account_Event__e>();
for(Account acc:trigger.new) {
Account_Event__e objEvent = new Account_Event__e();
objEvent.Account_Id__c = acc.Id;
lstPlatformEvent.add(objEvent);
}
if(!lstPlatformEvent.isempty()) {
EventBus.publish(lstPlatformEvent);
System.debug('Event:'+ lstPlatformEvent);
}
}
