All Implemented Interfaces:

com.esri.arcgis.interop.RemoteObjRef, INALocation, Serializable

public class NALocation
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, INALocation

Defines the side and position of an analysis object on a feature.

Remarks

An NALocation object specifies the side and position along a Feature in a NetworkDataset.

NALocation objects can be CoCreated, retrieved from an NALocationObject or NALocationFeature object by getting the NALocation property on the INALocationObject interface, or retrieved through the NALocator object.

Constructor Detail

NALocation

public NALocation()
           throws IOException,
                  UnknownHostException

Constructs a NALocation using ArcGIS Engine.

Throws:

IOException - if there are interop problems

UnknownHostException - if there are interop problems

NALocation

public NALocation(Object obj)
           throws IOException

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

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

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

setSourceID

public void setSourceID(int sourceID)
                 throws IOException,
                        AutomationException

The ID of the network source.

Remarks

The SourceID property specifies the SourceID of the feature class in the NetworkDataset that the NALocation is referencing. The SourceID of the feature class can be retrieved from the ID property on the INetworkSource interface.

Product Availability

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

Specified by:

setSourceID in interface INALocation

Parameters:

sourceID - The sourceID (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSourceID

public int getSourceID()
                throws IOException,
                       AutomationException

The ID of the network source.

Remarks

The SourceID property specifies the SourceID of the feature class in the NetworkDataset that the NALocation is referencing. The SourceID of the feature class can be retrieved from the ID property on the INetworkSource interface.

Product Availability

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

Specified by:

getSourceID in interface INALocation

Returns:

The sourceID

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setSourceOID

public void setSourceOID(int sourceOID)
                  throws IOException,
                         AutomationException

The OID of the feature.

Remarks

The SourceOID property specifies the ObjectID of the feature in the NetworkDataset that the NALocation is referencing. The SourceOID is used in conjunction with the SourceID to uniquely specify a Feature in the NetworkDataset.

Product Availability

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

Specified by:

setSourceOID in interface INALocation

Parameters:

sourceOID - The sourceOID (in)

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getSourceOID

public int getSourceOID()
                 throws IOException,
                        AutomationException

The OID of the feature.

Remarks

The SourceOID property specifies the ObjectID of the feature in the NetworkDataset that the NALocation is referencing. The SourceOID is used in conjunction with the SourceID to uniquely specify a Feature in the NetworkDataset.

Product Availability

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

Specified by:

getSourceOID in interface INALocation

Returns:

The sourceOID

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

setSourcePosition

public void setSourcePosition(double position)
                       throws IOException,
                              AutomationException

The position along the feature.

Remarks

The SourcePosition property specifies the position along the feature specified by the SourceID and SourceOID. Valid values are in the range of 0 to 1. A value of 0.25 would translate to 1/4 of the way along the source feature in the digitized direction.

Remarks

The Side property specifies the position of the NALocation in relation to the feature specified by the SourceID and SourceOID. Valid values are dictated by the enumeration esriNAEdgeSideType which has values esriNAEdgeSideRight (1) and esriNAEdgeSideLeft (2). The side is always in relation to the digitized direction of the feature.

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

Specified by:

setSide in interface INALocation

Parameters:

side - A com.esri.arcgis.networkanalyst.esriNAEdgeSideType constant (in)

Throws:

IOException - If there are interop problems.

getSide

public int getSide()
            throws IOException,
                   AutomationException

The side of the feature.

Remarks

The Side property specifies the position of the NALocation in relation to the feature specified by the SourceID and SourceOID. Valid values are dictated by the enumeration esriNAEdgeSideType, which has values esriNAEdgeSideRight (1) and esriNAEdgeSideLeft (2). The side is always in relation to the digitized direction of the feature.

                         AutomationException

Indicates if the location has been found on the network.

Remarks

This property returns True if the SourceID, SourceOID, SourcePosition, and Side properties all have valid values that should correspond to a position along a feature in a NetworkDataset.

Product Availability

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

Specified by:

isLocated in interface INALocation

Returns:

The located
