                        AutomationException

Direction in which this network edge element is oriented relative to the direction of its source object.

Remarks

The Direction property returns the direction of travel along this edge element relative to the digitized direction of the source feature. The direction of travel is either esriNEDAlongDigitized, meaning the direction of travel along the edge element is the same as the feature's direction of digitization, or esriNEDAgainstDigitized, meaning the direction of travel along the edge element is the opposite of the feature's direction of digitization.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Specified by:

getDirection in interface INetworkEdge

Returns:

A com.esri.arcgis.geodatabase.esriNetworkEdgeDirection constant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

                           AutomationException

Queries the positions along the source object at which the from-end and to-end of the network edge element lies.

Remarks

The QueryPositions method queries the positional values along the source feature from which this edge element was created. The position values range from 0.0 to 1.0, where 0.0 is at the from-end of the feature and 1.0 is at the to-end of the feature.

If the Direction property is esriNEDAlongDigitized, then the fromPosition value will be less than or equal to the toPositionValue. If the Direction property is esriNEDAgainstDigitized, then the fromPosition value will be greater than or equal to the toPositionValue.
