getFromToJunctionEIDs

public void getFromToJunctionEIDs(int edgeEID,
                                  int[] fromJunctionEID,
                                  int[] toJunctionEID)

                                  AutomationException

Returns the network element IDs of the junctions adjacent to the specified edge.

Remarks

GetFromToJunctionEIDs returns the Element IDs of the start (From) and end (To) junctions of the specified edge element.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getFromToJunctionEIDs in interface INetTopology

Parameters:

edgeEID - The edgeEID (in)

fromJunctionEID - The fromJunctionEID (out: use single element array)

toJunctionEID - The toJunctionEID (out: use single element array)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getAdjacentEdgeCount

public int getAdjacentEdgeCount(int atJunctionEID)
                         throws IOException,
                                AutomationException

Returns the number of edges adjacent to the specified junction.

Remarks

GetAdjacentEdgeCount returns the number of edges connect to the specified junction. This property is often used in conjunction with GetAdjacentEdge or GetAdjacentEdges to loop through the edges connected to a junction.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getAdjacentEdgeCount in interface INetTopology

Parameters:

atJunctionEID - The atJunctionEID (in)

Returns:

The adjacentEdgesCount

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getAdjacentEdge

public void getAdjacentEdge(int atJunctionEID,
                            int index,
                            int[] adjacentEdge,
                            boolean[] reverseOrientation)
                     throws IOException,
                            AutomationException

Returns the network element ID of the index'th adjacent edge to the specified junction.

Remarks

The GetAdjacentEdge function returns the Element ID of the adjacent edge found at the atJunctionEID that corresponds to the index value.

A ReverseOrientation of True indicates that the Junction is at the To end of the edge, while False indicates the opposite.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:

getAdjacentEdge in interface INetTopology

Parameters:

atJunctionEID - The atJunctionEID (in)

index - The index (in)

adjacentEdge - The adjacentEdge (out: use single element array)

reverseOrientation - The reverseOrientation (out: use single element array)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getAdjacentEdges

public void getAdjacentEdges(int atJunctionEID,
                             int adjacentEdgesCount,
                             int[] adjacentEdges,
                             boolean[] reverseOrientation)
                      throws IOException,
                             AutomationException

Returns the network element IDs of all the edges adjacent to the specified junction.

Remarks

GetAdjacentEdges returns an array of the edges connected to the specified junction, along with their orientation.

A ReverseOrientation of True indicates that the Junction is at the To end of the edge, while False indicates the opposite.

INetTopology::GetAdjacentEdges is marked as hidden, since its functionality is similar to IForwardStar::QueryAdjacentEdges(). Clients should use QueryAdjacentEdges, or even use IForwardStarGEN::QueryAdjacentEdges, in lieu of using INetTopology::GetAdjacentEdges.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

This method is not callable from Java. Please see INetTopologyEditGEN::GetAdjacentEdges.

Specified by:

getAdjacentEdges in interface INetTopology

Parameters:

atJunctionEID - The atJunctionEID (in)

adjacentEdges - The adjacentEdges (out: use single element array)

reverseOrientation - The reverseOrientation (out: use single element array)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
