| NALayer | The layer for defining, solving, and viewing network analysis results. |
The INALayer2 interface is used to access the NAContext, access individual sublayers by specifying the name of the NAClass, manage the sublayers within the NALayer, as well as manage the state of an NALayer's context within the server environment.
CopyContext makes a copy of the NALayer's NAContext that can be persisted within a user's session state. AttachContext re-attaches an NAContext to the NALayer.
CopyContext, AttachContext, and DataLayerByNAClassName should not be used from within ArcMap because user interface components listening to events on the NAContext will not have an opportunity to switch to the new NAContext.
