Disable Event Firing in SharePoint

A colleague of mine just sent me this code. Disable Event Firing from anywhere in your code.

 
  public class HandleEventFiring : SPItemEventReceiver
  {
     public HandleEventFiring()
     {
     }
     public void CustomDisableEventFiring()
     {
        this.DisableEventFiring();
     }
     public void CustomEnableEventFiring()
     {
        this.EnableEventFiring();
     }
  }

Use like this:

 
  SPWeb web = site.RootWeb;
  SPList list = site.RootWeb.Lists["Testing"];
  SPListItem item = list.GetItemById(2);

  //update item properties
  
  HandleEventFiring eventFiring = new HandleEventFiring();
  eventFiring.CustomDisableEventFiring();
  item.SystemUpdate();
  eventFiring.CustomEnableEventFiring();
