A connectivity, containment, or structural attachment association. Associations are an integral part of network topology. Connectivity associations allow connectivity between two junctions that don't have geometric coincidence (are not in the same location). Structural attachment associations allow modeling equipment attached to structures. Containment associations allow modeling containment of features within other features. Network traces make use of associations. Associations are defined using two UtilityElement objects.
The relative location along the non-spatial edge where the junction is (logically) located. If this is a junction to a non-spatial edge connectivity association, this property represents how far the junction is located along the non-spatial edge, from 0.0 (the edge's start point) and 1.0 (the edge's end point).
The geometry of this UtilityAssociation. This geometry represents the connection between UtilityAssociation.fromElement and UtilityAssociation.toElement. This property is valid only on connectivity and structural attachment UtilityAssociation objects returned by UtilityNetwork.getAssociations(Envelope) or UtilityNetwork.getAssociations(Envelope, UtilityAssociationType).
