com.esri.arcgis.geodatabase
Class IUtilityNetworkProxy

java.lang.Object
  com.esri.arcgis.interop.Dispatch
      com.esri.arcgis.geodatabase.INetworkProxy
          com.esri.arcgis.geodatabase.IUtilityNetworkProxy

All Implemented Interfaces:

INetwork, IUtilityNetwork, Externalizable, Serializable

Direct Known Subclasses:

IUtilityNetwork2Proxy

public class IUtilityNetworkProxy
extends INetworkProxy
implements IUtilityNetwork, Serializable

Provides access to members that get and set flow direction in a utility network.

Superseded By

IUtilityNetwork2

Remarks

The only elements in a network that can have flow are edge elements. Junction elements do not have flow.

Flow is maintained in the logical network and not the geometric network. Unlike creating flags, which is done on a feature in the geometric network, changing flow direction on individual elements requires that you directly manipulate the logical network.

This operation requires that you make the network editable. You can do this either through an edit session, using the Editor, or you can use the IWorkspaceEdit interface to edit the workspace of the logical network.

When To Use

Use the IUtilityNetwork interface for establishing flow direction for your network. You can also use this interface to check the flow direction for a particular element and change the flow direction on a particular element.

Product Availability

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

addListener

public void addListener(String iidStr,
                        Object theListener,
                        Object theSource)
                 throws IOException

Overrides:

Throws:

IOException

public void removeListener(String iidStr,
                           Object theListener)
                    throws IOException

isValidFlowDirection

public boolean isValidFlowDirection()
                             throws IOException,
                                    AutomationException

Indicates if the flow direction is valid for this utility network.

Remarks

ValidFlowDirection specifies whether the logical network has flow direction defined on it. Use EstablishFlowDirection on this same interface to set the flow direction.

In this release, ValidFlowDirection is not implemented -- for now, this property always returns False.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

isValidFlowDirection in interface IUtilityNetwork

Returns:

The validFlowDirection

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getFlowDirection

public int getFlowDirection(int edgeEID)
                     throws IOException,
                            AutomationException

Returns the flow direction of the specified edge element.

Remarks

GetFlowDirection returns the flow direction for the specified edge element. Possible flow directions are (with and against values are in relation to the digitized direction of the element):

esriFDAgainstFlow

esriFDIndeterminate

esriFDUninitialized

esriFDWithFlow

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

Parameters:

edgeEID - The edgeEID (in)

Returns:

A com.esri.arcgis.geodatabase.esriFlowDirection constant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setFlowDirection

public void setFlowDirection(int edgeEID,
                             int flowDirection)
                      throws IOException,
                             AutomationException

Remarks

esriFDAgainstFlow

esriFDIndeterminate

esriFDUninitialized

esriFDWithFlow

This operation requires that you make the network editable. You can do this either through an edit session, using the Editor, or you can use the IWorkspaceEdit interface to edit the workspace of the logical network.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:

setFlowDirection in interface IUtilityNetwork

Parameters:

edgeEID - The edgeEID (in)

flowDirection - A com.esri.arcgis.geodatabase.esriFlowDirection constant (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

establishFlowDirection

public void establishFlowDirection(int sourceCount,
                                   int[] sourceEIDs,
                                   int sinkCount,
                                   int[] sinkEIDs)
                            throws IOException,
                                   AutomationException

Sets the flow direction of all edge elements based on the placement of sources and sinks.

Remarks

EstablishFlowDirection will set the flow direction for the entire network based on the input sources (starting points) and/or sinks (collection points). In the majority of cases your network will have either sources or sinks, but not both. Having both sources and sinks in your network will often lead to indeterminate flow on the edge elements. Any edge elements that cannot be reached from the specified sources and/or sinks will have uninitialized flow.

The flow direction established on the edges will be based on these possible values:

esriFDAgainstFlow
esriFDIndeterminate
esriFDUninitialized
esriFDWithFlow

This operation requires that you make the network editable. You can do this either through an edit session, using the Editor, or you can use the IWorkspaceEdit interface to edit the workspace of the logical network.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux
