Interface INetworkClass

All Superinterfaces:

IClass, IFeatureClass, IObjectClass, java.io.Serializable

All Known Implementing Classes:

FeatureClass, INetworkClassProxy

public interface INetworkClass

extends IFeatureClass, java.io.Serializable

Provides access to members that return information about geometric networks, field weighting and ancillary roles.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

When To Use

Use the INetworkClass interface to get a reference to the geometric network which the network class (feature class) belongs to. You can also check to see if the network class has an Ancillary Role in the network, and the right to field mapping for the logical network.

The INetworkClass interface inherits from the IFeatureClass interface and the ITable interface.

Remarks

The FeatureType property of such feature classes will be one of esriFTSimpleJunction, esriDTSimpleEdge, esriFTComplexJunction, or esriFTComplexEdge.

You can QI (Query Interface) to any of these other interfaces on the FeatureClass object.

Method Summary

int	getFieldToWeightMapping(int fieldIndex) The specified field to Weight mapping for the logical network.
IGeometricNetwork	getGeometricNetwork() The geometric network in which this class participates.

Method Detail

getGeometricNetwork

public IGeometricNetwork getGeometricNetwork()
                                      throws java.io.IOException,
                                             AutomationException

The geometric network in which this class participates.

Supported Platforms

Windows, Solaris, Linux

Remarks

The GeomtricNetwork property returns an IGeometricNetwork interface to the geometric network in which the network feature class participates.

Returns:

A reference to a com.esri.arcgis.geodatabase.IGeometricNetwork

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

IGeometricNetwork, INetwork

getFieldToWeightMapping

public int getFieldToWeightMapping(int fieldIndex)
                            throws java.io.IOException,
                                   AutomationException

The specified field to Weight mapping for the logical network.

Supported Platforms

Windows, Solaris, Linux

Remarks

The FieldToWeightMapping property will return the index of the network weight to which a field in the network class is mapped in the logical network. You can then use the INetSchema::Weight property to return the INetWeight interface on that particular network weight. If the field has no weight associated with it, FieldToWeightMapping returns a -1.

Parameters:

fieldIndex - The fieldIndex (in)

Returns:

The weightID

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

IGeometricNetwork, INetwork, INetWeight

getNetworkAncillaryRole

public int getNetworkAncillaryRole()
                            throws java.io.IOException,
                                   AutomationException

The possible network ancillary roles of the contained Features.

Supported Platforms

Windows, Solaris, Linux

Remarks

The NetworkAncillaryRole property will return the esriNetworkAncillaryRole enumeration which indicates if the junction class has a network ancillary role. Since junctions in a geometric network can act as a source, a sink or neither when calculating flow direction, this property will indicate whether or not the features in the class can be sources or sinks. If the class is a simple edge or complex edge network class, the ancillary role will always be returned as esriNCARNone since only junctions may have ancillary roles.

Returns:

A com.esri.arcgis.geodatabase.esriNetworkClassAncillaryRole constant

Throws:

java.io.IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
