Constructor Detail

EIDHelper

public EIDHelper()
          throws IOException,
                 UnknownHostException
Constructs a EIDHelper using ArcGIS Engine.

Throws:
IOException - if there are interop problems
UnknownHostException - if there are interop problems

EIDHelper

public EIDHelper(Object obj)
          throws IOException
Deprecated. As of ArcGIS 9.2, replaced by normal Java casts.
EIDHelper theEIDHelper = (EIDHelper) obj;

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

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

setGeometricNetworkByRef

public void setGeometricNetworkByRef(IGeometricNetwork rhs1)
                              throws IOException,
                                     AutomationException
Geometric network from which these element IDs come.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Specified by:
setGeometricNetworkByRef in interface IEIDHelper
Parameters:
rhs1 - A reference to a com.esri.arcgis.geodatabase.IGeometricNetwork (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

addField

public void addField(String field)
              throws IOException,
                     AutomationException
Adds a field to the list of fields to return with the feature.

Remarks

Feature objects returned by this EIDHelper object are meant only for querying attribute values from the features and not for editing the features. These feature objects will only contain those fields specified using AddField. For optimization purposes, if no calls are made to AddField before calling CreateEnumEIDInfo, the feature objects returned will only contain the OID and Shape fields.

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

Supported Platforms

Windows, Solaris, Linux

Specified by:
addField in interface IEIDHelper
Parameters:
field - The field (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

clearFields

public void clearFields()
                 throws IOException,
                        AutomationException
Clears the list of fields to return with the feature.

Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.
