Used to batch operations together and minimize notifications.
[Visual Basic .NET] Public Sub DelayEvents ( _ ByVal delay As Boolean _ )
Available with ArcGIS Desktop.
Use DelayEvents to control whether or not the topology extension calls event notifications. This can be desirable when working with topology selections. For example, instead of the topology extension calling ITopologyExtensionEvents::OnTopologySelectionChanged every time you select a topology element, you may want the extension to only fire this event once when the entire selection process is complete.
