IFeature Interface

Provides access to members that return and set properties of a feature.

Product Availability

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

Members

	HasOID	Indicates if the row has an OID.
	OID	The OID for the row.
	Shape	A reference to the default shape for the feature.
	ShapeCopy	A cloned copy of the default shape for the feature.

Remarks

A Feature is a spatial Object. It is also a member of a feature class, being a row in the feature class table. A feature has an associated shape, the
type of which is defined by the feature class. The possible shape objects are Point, Multipoint, Multipatch, Polyline, and Polygon—these are all objects in the Geometry object model. For more details, see the discussion on the GeometryDef object.

Most likely, you will deal with simple features, but there are various special kinds as defined by the esriFeatureType enumeration. These include
annotation, dimension, and various network features.

One thing to note is that all features still have the same core geometry types of point, multipoint, line, and polygon; an example of this is the annotation feature, whose geometry type is polygon—this represents the envelope of the text element. All the discussion for Row and Object is appropriate to Feature objects.

The IFeature interface extends IObject and IRow from which it inherits. The additional facilities are to do with the shape of the feature. You can use the Shape property to get or set the shape. This can be much more convenient than the alternative of using the Value property, since you don’t have to work out the index of the shape field.

The Shape property is the main link in ArcObjects between the geometry and geodatabase object models.

The ShapeCopy property is a cloned copy of the feature’s Shape. It is commonly used when modifying the geometry of a set of features.

Using C++, you can also define your own custom features with specialized behavior.
