A container for describing a network dataset source whose elements are derived from turn feature geometry.

Description

A turn feature source is a turn feature class that is used to generate turn elements into a network dataset. A TurnFeatureSource object is a light weight object that holds the information about a turn feature source in a network dataset.

The TurnFeatureSource object for an existing network dataset can be accessed through the INetworkDataset interface.

Constructor Detail

TurnFeatureSource

public TurnFeatureSource()
                  throws IOException,
                         UnknownHostException

Constructs a TurnFeatureSource using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

TurnFeatureSource

public TurnFeatureSource(Object obj)
                  throws IOException

Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
TurnFeatureSource theTurnFeatureSource = (TurnFeatureSource) obj;

Construct a TurnFeatureSource using a reference to such an object returned from ArcGIS Engine or Server. This is semantically equivalent to casting obj to TurnFeatureSource.

Parameters:

obj - an object returned from ArcGIS Engine or Server

Throws:

IOException - if there are interop problems

Method Detail

getClsid

public static String getClsid()

getClsid.

equals

public boolean equals(Object o)

Compare this object with another

Overrides:

equals in class Object

hashCode

public int hashCode()

the hashcode for this object

Overrides:

hashCode in class Object

getID

public int getID()
          throws IOException,
                 AutomationException

Unique identifier of this network source.

Remarks

Each source in a Network Dataset is identified by a unique value, the ID property. The ID property can be used to get a reference to the corresponding network source through the INetworkDataset::SourceByID property. This ID is different than the ID value returned by the IObjectClass::ObjectClassID property.

As with ObjectID values, SourceID values are never reused. They are not guaranteed to be sequential, but are guaranteed to be in increasing order based on when the source was added to the network. Unless the source is added or deleted from the DataElement, the SourceID values will remain constant after the INetworkDataset::UpdateSchema method is called.

Product Availability

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

Specified by:

getID in interface INetworkSource

Returns:

The iD

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getElementType

public int getElementType()
                   throws IOException,
                          AutomationException

Network element type of this network source.

Product Availability

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

Specified by:

getElementType in interface INetworkSource

Returns:

A com.esri.arcgis.geodatabase.esriNetworkElementType constant

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setElementType

public void setElementType(int elementType)
                    throws IOException,
                           AutomationException

Network element type of this network source.

Product Availability

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

Specified by:

setElementType in interface INetworkSource

Parameters:

elementType - A com.esri.arcgis.geodatabase.esriNetworkElementType constant (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getName

public String getName()
               throws IOException,
                      AutomationException

Name of the class associated with this network source.

Remarks

The Name property for the NetworkSource is exactly the same as the name of the reference FeatureClass. The feature classes that participate in the network dataset can be opened from the NetworkDataset by simply calling IFeatureClassContainer::ClassByName and passing in this Name.

NOTE: For SDC network datasets, not all network sources have a reference feature class. Only those feature classes returned in the IFeatureClassContainer::Classes enumeration can be opened.

Unlike other network dataset types, the source names for an SDC network dataset are not the same as the feature class names of the SDC feature classes. For SDC data, the source name for the edge feature source is the same as the network dataset name (obtained from IDataset::Name).

Product Availability

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

Specified by:

getName in interface INetworkSource

The sourceName

Throws:

IOException - If there are interop problems.

isUsesGeometryInConnectivity

public boolean isUsesGeometryInConnectivity()
                                     throws IOException,
                                            AutomationException

Indicates if the source object's geometry is used in determining network connectivity.

Remarks

The UsesGeometryInConnectivity property indicates whether the geometries of the features in a NetworkSource are used in determining how its network elements are connected to each other.

For example, the geometries of the features in an EdgeFeatureSource and JunctionFeatureSource are used to determine how the generated edge and junction elements connect to each other. The UsesGeometryInConnectivity property for these sources is True.

In contrast, the geometries of the features in a TurnFeatureSource are not used in deteriming how the turn elements are associated with the edges and junctions of the network -- the fields of the TurnFeatureSource feature class determine this. The UsesGeometryInConnectivity property for the TurnFeatureSource is False.

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

isUsesGeometryInConnectivity in interface INetworkSource
