IFeature Interface

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

Members

	Name	Description
	Class	The Object Class for the row.
	Delete	Deletes the row.
	Extent	The extent of the feature.
	FeatureType	The type of the feature.
	Fields	The fields Collection for this row buffer.
	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.
	Store	Stores the row.
	Table	The Table for the row.
	Value	The value of the field with the specified index.

IFeature.Extent Property

The extent of the feature.

Public ReadOnly Property Extent As IEnvelope

public IEnvelope Extent {get;}

IFeature.FeatureType Property

The type of the feature.

Public ReadOnly Property FeatureType As esriFeatureType

public esriFeatureType FeatureType {get;}

IFeature.Shape Property

A reference to the default shape for the feature.

Public Property Shape As IGeometry

public IGeometry Shape {get; set;}

Remarks

The basic process to change the shape of a feature is:

1) Get the feature's existing geometry through IFeature.ShapeCopy or create a new geometry2) Modify the geometry3) Set the feature's geometry using IFeature.Shape4) Store the feature

All edits to features that participate in a Topology or Geometric Network must be performed within an edit session and bracketed within an edit operation.

IFeature.ShapeCopy Property

A cloned copy of the default shape for the feature.

Public ReadOnly Property ShapeCopy As IGeometry

public IGeometry ShapeCopy {get;}

Remarks

The ShapeCopyproperty is a cloned copy of the feature�s Shape. When modifying the geometry of a feature or a set of features, use the ShapeCopy property to obtain a copy of the feature's geometry, perform the modification on the geometries, then apply the modifications by setting the geometry to the Shape property.

Inherited Interfaces

Interfaces	Description
IObject	Provides access to the class the row belongs to.
IRow	Provides access to members that return information about the row, the table the row belongs to and storing and deleting the row.
IRowBuffer	Provides access to members used for getting and modifying a rows values and for getting the fields in the row.

Classes that implement IFeature

Classes	Description
Feature	Esri Feature.

Remarks

Features are spatial Objects. They are contained in a feature class in the same way that a row is contained in a table, and an object is contained in an object class. 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 library. For more details, see the IGeometryDefinterface.

One thing to note is that all features still have the same core geometry types of point, multipoint, polyline, polygon and multipatch; an example of this is the annotation feature, whose geometry type is polygon - this represents the envelope of the text element.

The IFeatureinterface extends the IObjectand IRowinterfaces, and as such, the documentation for those interfaces applies to this interface. The additional functionality relates to the features' shapes, accessed and set through the Shapeproperty. This can be much more convenient than the alternative of using the Valueproperty, since you don�t have to determine the index of the shape field. The Shapeproperty is the main link in ArcObjects between the geometry and geodatabase object models.

The ShapeCopyproperty is a cloned copy of the feature�s Shape. When modifying the geometry of a feature or a set of features, use the ShapeCopy property to obtain a copy of the feature's geometry, perform the modification on the geometries, then apply the modifications by setting the geometry to the Shape property.

There are several Feature subclasses which can also be accessed using the IFeature interface. These include annotation, dimension, and network features.
