public interface IFeatureChanges
extends Serializable

Provides access to members that provide information about changes in the feature's shape.

Remarks

The IFeatureChanges interface is used to analyze an object and determine which shape fields have been modified.

Product Availability

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

Method Summary

IGeometry	getOriginalShape() The original shape for the feature.
boolean	isShapeChanged() Indicates if the shape has changed.

Method Detail

isShapeChanged

boolean isShapeChanged()
                       throws IOException,
                              AutomationException

Indicates if the shape has changed.

Remarks

IFeatureChanges::ShapeChanged can be used to determine if a feature's geometry has changed. If the feature's geometry has been changed, but IRow::Store has not yet been called, ShapeChanged will return True. Once Store is called, ShapeChanged will return False. ShapeChanged can also be used in an event triggered by Store, such as IRowEvents::OnChanged. When used in this manner, ShapeChanged will return True if the feature's shape has changed. Once Store is complete, ShapeChanged will return false.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

The changed

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.

getOriginalShape

IGeometry getOriginalShape()
                           throws IOException,
                                  AutomationException

The original shape for the feature.

Product Availability

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

Supported Platforms

Windows, Solaris, Linux

Returns:

A reference to a com.esri.arcgis.geometry.IGeometry

Throws:

IOException - If there are interop problems.

AutomationException - If the ArcObject component throws an exception.
