Syntax

Visual Basic (Declaration)
C#

Public Function New( _
   ByVal type As AssociationType, _

)

public Association( 
   AssociationType type,
   Element fromElement,
   Element toElement
)

Parameters

type

The type of association between and .

fromElement

An Element representing the from element if type is AssociationType.JunctionJunctionConnectivity.
An Element representing the container element if type is AssociationType.Containment.
An Element representing the structure element if type is AssociationType.Attachment.
An Element representing the junction or non-spatial junction object connecting to the from side of the edge object if type is AssociationType.JunctionEdgeObjectConnectivityFromSide.
An Element representing the junction or non-spatial junction object connecting to the to side of the edge object if type is AssociationType.JunctionEdgeObjectConnectivityToSide.

toElement

An Element representing the to element if type is AssociationType.JunctionJunctionConnectivity.
An Element representing the content element if type is AssociationType.Containment.
An Element representing the attachment element if type is AssociationType.Attachment.
An Element representing the edge object connected to its from side by a junction or non-spatial junction object if type is AssociationType.JunctionEdgeObjectConnectivityFromSide.
An Element representing the edge object connected to its to side by a junction or non-spatial junction object if type is AssociationType.JunctionEdgeObjectConnectivityToSide.

Exceptions

Exception	Description
System.ArgumentOutOfRangeException	type is invalid.
System.ArgumentNullException	fromElement or toElement is null.
System.ArgumentException	type is AssociationType.JunctionEdgeObjectConnectivityMidspan.

Remarks

If type is AssociationType.Containment, the overloaded Association Constructor(AssociationType,Element,Element,ContainmentVisibility) should be used instead.
If type is AssociationType.JunctionEdgeObjectConnectivityMidspan, the overloaded Association Constructor(AssociationType,Element,Element,Double) should be used instead.

Example

Add or delete an association between Telecom elements in the utility network

await QueuedTask.Run(() =>
{
  using (NetworkSource junctionNetworkSource = telecomDomainNetwork.NetworkSources.FirstOrDefault(ns => ns.Name.Contains("TelcoDevice")))
  using (NetworkSource edgeNetworkSource = telecomDomainNetwork.NetworkSources.FirstOrDefault(ns => ns.Name.Contains("TelcoEdgeObject")))
  {
    TelecomElement junction = utilityNetwork.CreateElement(junctionNetworkSource.GetAssetGroup("Fiber").GetAssetType("Fiber"),
              new Guid("CCFCF5DE-5B90-4FD9-A459-2F2E88107532")) as TelecomElement;

    TelecomElement edgeObject = utilityNetwork.CreateElement(edgeNetworkSource.GetAssetGroup("Fiber").GetAssetType("Fiber"),
              new Guid("838B4A2B-8531-499D-8DCF-8567901D43D9")) as TelecomElement;

    Association association = new Association(AssociationType.JunctionEdgeObjectConnectivityMidspan, junction, edgeObject, 0.3);

    // Create the association from the port to the fiber.
    geodatabase.ApplyEdits(() =>
          {
            utilityNetwork.AddAssociation(association);
          });
    // Delete the association
    geodatabase.ApplyEdits(() =>
          {
            utilityNetwork.DeleteAssociation(association);
          });
  }

});
