Product Availability

Available with ArcGIS Engine.

Method Summary

void	onCurrentNetworkLayerChanged(IEngineNetworkAnalystEnvironmentEventsOnCurrentNetworkLayerChangedEvent theEvent) Called when the current network layer has changed.
void	onNetworkLayersChanged(IEngineNetworkAnalystEnvironmentEventsOnNetworkLayersChangedEvent theEvent) Called when the network layers have changed.

Method Detail

onNetworkLayersChanged

void onNetworkLayersChanged(IEngineNetworkAnalystEnvironmentEventsOnNetworkLayersChangedEvent theEvent)
