Constructor Detail

LayerResultOptions

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

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

LayerResultOptions

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

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

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

setIncludeGeometry

public void setIncludeGeometry(boolean includeGeometry)
                        throws IOException,
                               AutomationException
Indicates whether we should include Geometry.

Product Availability

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

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

isIncludeGeometry

public boolean isIncludeGeometry()
                          throws IOException,
                                 AutomationException
Indicates whether we should include Geometry.

Remarks

If IncludeGeometry is set to False, no geometry is returned. This should increase performance in cases where feature geometry is large. The default value for IncludeGeometry is True.

QueryHyperLinks() always returns geometry regardless InlcudeGeometry’s value.

Product Availability

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

Specified by:
isIncludeGeometry in interface ILayerResultOptions
Returns:
The includeGeometry
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setGeometryResultOptionsByRef

public void setGeometryResultOptionsByRef(IGeometryResultOptions geometryOptions)
                                   throws IOException,
                                          AutomationException
Indicates whether we need to modify Geometry.

Product Availability

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

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

getGeometryResultOptions

public IGeometryResultOptions getGeometryResultOptions()
                                                throws IOException,
                                                       AutomationException
Indicates whether we need to modify Geometry.

Remarks

Use GeometryResultOptions to densify or generalize the geometry returned from a query. Densification is used to better support clients that do not support Arcs (e.g. Bezier, Circular etc.). Generalization reduces the amount of geography being sent across the network and should lead to better performance.

QueryHyperLinks() honors GeometryResultOptions.

Product Availability

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

Specified by:
getGeometryResultOptions in interface ILayerResultOptions
Returns:
A reference to a com.esri.arcgis.geodatabase.IGeometryResultOptions
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setReturnFieldNamesInResults

public void setReturnFieldNamesInResults(boolean returnFieldName)
                                  throws IOException,
                                         AutomationException
Indicates whether to include field name or alias.

Product Availability

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

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

isReturnFieldNamesInResults

public boolean isReturnFieldNamesInResults()
                                    throws IOException,
                                           AutomationException
Indicates whether to include field name or alias.

Description

ReturnFieldNamesInResults is only applied to Find and Identify functions. It is ignored by QueryFeatureData2, QueryFeatureIDs2, QueryFeatureCount2 & QueryHyperLinks functions. The default value for ReturnFieldNamesInResults is False – that means if it is not set explicitly, field aliases set in the source map document will be honored in Find and Identify results. For example, if a field named “CNTRY_NM” has an alias set to “Country Name” in the original map document, a Find or Identify result will display “Country Name”. When ReturnFieldNamesInResult set to True, the field name “CNTRY_NM” will be returned instead of the alias.

This property is ignored by Identify and Find functions when querying a layer that does not implement the IFeatureLayer interface (i.e. Raster layer)

Product Availability

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

Specified by:
isReturnFieldNamesInResults in interface ILayerResultOptions
Returns:
The returnFieldName
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setFormatValuesInResults

public void setFormatValuesInResults(boolean format)
                              throws IOException,
                                     AutomationException
Indicates whether to format the values in results.

Product Availability

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

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

isFormatValuesInResults

public boolean isFormatValuesInResults()
                                throws IOException,
                                       AutomationException
Indicates whether to format the values in results.

Remarks

FormatValuesInResults is only applied to Find and Identify functions. It is ignored by QueryFeatureData2, QueryFeatureIDs2, QueryFeatureCount2 & QueryHyperLinks functions. The default value for FormatValuesInResults is True – that means if it is not set explicitly, field formatting set in the source map document will be honored. For example, if the format for a field of type double is set to have thousand separator and 3 digits after decimal, the output will be a string “999,999.999”. When it is set to False, values will be returned in the source data type, for the same case, the returned value will be a double 999999.9999999.

This property is ignored by Identify and Find functions when querying a layer that does not implement IFeatureLayer interface (i.e. Raster layer)

Product Availability

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

Specified by:
isFormatValuesInResults in interface ILayerResultOptions

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

Remarks

Use IsSupportedAtVersion to identify if a particular object should be saved to the ObjectStream. This result is based on the esriArcGISVersion enumeration. In some instances, if the object is not supported at a particular ArcGIS version, the object may support conversion to another similar object; use IDocumentVersionSupportGEN::ConvertToSupportedObject to accomplish this.

Product Availability

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

Specified by:
isSupportedAtVersion in interface IDocumentVersionSupportGEN
Parameters:
docVersion - A com.esri.arcgis.system.esriArcGISVersion constant (in)
