fractionAlongEdge property

The relative location along the non-spatial edge where the junction is (logically) located.

If this is a junction in a non-spatial edge connectivity association, this property represents the relative location of the junction along the non-spatial edge, ranging from 0.0 (the edge's start point) to 1.0 (the edge's end point).

For an UtilityAssociationType.junctionEdgeObjectConnectivityToSide association, the value is 0.0; if UtilityAssociationType.junctionEdgeObjectConnectivityMidspan, the value is between 0.0 and 1.0; and if UtilityAssociationType.junctionEdgeObjectConnectivityFromSide, the value is 1.0.

This property is equivalent to percent along value in other parts of the ArcGIS platform. For example, ArcGIS REST /query and ArcGIS Pro Associations Table

The default value is 0.0.
