Remarks

The SourceID parameter is the unique ID assigned to the NetworkSource in the network dataset.

The fromPosition and toPosition parameters refer to 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.

The EnumNetworkElement enumeration object returned by the EdgesBySegment property is recycling.  For enumerations with more than one network element returned, this means that the network element object returned by the first call to Next is expected to be reused in subsequent calls to Next.

If the fromPosition parameter is greater than the toPosition parameter, the edge element(s) returned in the enumeration will be oriented in the esriNEDAgainstDigitized Direction.
