ArcGIS.Desktop.Editing Namespace / AssociationDescription Class / AssociationDescription Constructor / AssociationDescription Constructor(AssociationType,RowHandle,RowHandle)
The association type.
The first row in the association.
The second row in the association.
Example

AssociationDescription Constructor(AssociationType,RowHandle,RowHandle)
Creates a new utility network AssociationDescription of the specified type. Use this constructor for
Syntax
public AssociationDescription( 
   AssociationType type,
   RowHandle row1,
   RowHandle row2
)

Parameters

type
The association type.
row1
The first row in the association.
row2
The second row in the association.
Remarks
A utility network structural attachment association is defined between a structure row (row1) and an attachment row (row2). A utility network connectivity association is defined by two junction rows that are not geometrically coincident. A utility network junction-edge "from side" object connectivity association represents a junction or non-spatial junction object (row1) connecting to the "from" side of a non-spatial edge object (row2). A utility network junction-edge "to side" object connectivity association represents a junction or non-spatial junction object (row1) connecting to the "to" side of a non-spatial edge object (row2).

If type is ArcGIS.Core.Data.UtilityNetwork.AssociationType.Containment, the overloaded AssociationDescription Constructor(AssociationType,RowHandle,RowHandle,Boolean) should be used instead.

If type is ArcGIS.Core.Data.UtilityNetwork.AssociationType.JunctionEdgeObjectConnectivityMidspan, the overloaded AssociationDescription Constructor(AssociationType,RowHandle,RowHandle,Double) should be used instead.
Example
Create a utility network association
// Create edit operation
EditOperation editOperation = new EditOperation();
editOperation.Name = "Create structural attachment association";

// Create a RowHandle for the pole

Element poleElement = utilityNetwork.CreateElement(poleAssetType, poleGlobalID);
RowHandle poleRowHandle = new RowHandle(poleElement, utilityNetwork);

// Create a RowHandle for the transformer bank

Element transformerBankElement = utilityNetwork.CreateElement(transformerBankAssetType, transformerBankGlobalID);
RowHandle transformerBankRowHandle = new RowHandle(transformerBankElement, utilityNetwork);

// Attach the transformer bank to the pole

AssociationDescription structuralAttachmentAssociationDescription = new AssociationDescription(AssociationType.Attachment, poleRowHandle, transformerBankRowHandle);
editOperation.Create(structuralAttachmentAssociationDescription);
editOperation.Execute();
