ArcObjects Library Reference (GeoDatabase)  

IFeatureCursor Interface

Provides access to members that hand out enumerated features, field collections and allows for the updating, deleting and inserting of features.

Product Availability

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

Members

Description
Method DeleteFeature Delete the existing Feature in the database corresponding to the current position of the cursor.
Read-only property Fields The fields Collection for this cursor.
Method FindField The index of the field with the specified name.
Method Flush Flush any outstanding buffered writes to the database.
Method InsertFeature Insert a new Feature into the database using the property values in the input buffer. The ID of the new Feature is returned.
Method NextFeature Advance the position of the cursor by one and return the Feature object at that position.
Method UpdateFeature Update the existing Feature in the database corresponding to the current position of the cursor.

CoClasses that implement IFeatureCursor

CoClasses and Classes Description
FeatureCursor Esri Feature Cursor object.
RelQueryCursor A cursor that is opened from a RelQueryTable.
TemporalCursor (esriTrackingAnalyst) Controls settings for the temporal cursor.

Remarks

The IFeatureCursor interface provides access to a set of features in a feature class. It operates in the same way as ICursor, although it does not inherit from that interface. This saves you from having to use Query-Interface when dealing with features rather than rows.

Feature cursors can be used as an input to IFeatureCursorBuffer, which lets you spatially buffer the features by a distance.

You can also draw the features from a cursor on the display. For more information, see the IFeatureRenderer::Draw method.

When using cursors within an edit session, they should always be scoped to edit operations. In other words, a cursor should be created after an edit operation has begun and should not be used once that edit operation has been stopped or aborted.
