Available with ArcGIS Desktop.
Remarks
The Network Analysis Extension manages the feature layers for the current network. Only those feature layers added to the Extension are considered when the user interacts with the map, such as adding flags and barriers using the Flag and Barrier tools, displaying the flow arrows, and drawing the results of a trace task.
The AddLayer method adds a reference to a feature layer to the Network Analysis Extension. If the geometric network to which the feature layer's feature class belongs is not loaded into the Extension, then the geometric network is added into the Extension.
Feature layers are added to the Extension using the AddLayer method, and removed using the DropLayer method. The AddNetwork method does not explicitly add layers to the Extension.
