FFLIB Cliff Notes: Trigger Implementations:

   public virtual void onBeforeInsert() { }
   public virtual void onBeforeUpdate(Map<Id,SObject> existingRecords) { }
   public virtual void onBeforeDelete() { }
   public virtual void onAfterInsert() { }
   public virtual void onAfterUpdate(Map<Id,SObject> existingRecords) { }
   public virtual void onAfterDelete() { }	
   public virtual void onAfterUndelete() { }

//Handlers

   public virtual void handleBeforeInsert() 
   public virtual void handleBeforeUpdate(Map<Id,SObject> existingRecords) 
   public virtual void handleBeforeDelete() 
   public virtual void handleAfterInsert()
   public virtual void handleAfterUpdate(Map<Id,SObject> existingRecords) 
   public virtual void handleAfterDelete() 
   public virtual void handleAfterUndelete()

Trigger Imp:

 Domain class: use Implementation tag 
     example: 
           public override void onBeforeInsert()                                                                                                                                               {OpportunitiesService.handleBeforeInsert(Records);
	}

Service Class: Create Handler

public static void handleBeforeInsert(List<SObject> records) {

triggerService(records).handleBeforeInsert();

}

Implementation class:

public override void onBeforeInsert(List<SObject> records) {

//business logic goes here

}
