Remarks

Insert creates an insert cursor on the feature class which can be used to insert new features into it.

Insert cursors can be used on instances of feature subclasses (such as network features) with guaranteed polymorphic behavior. Insert cursors can be used either inside or outside of an edit session. If used inside an edit session, the changes are not committed to the base table until the edit session is saved. Network feature classes, Topology feature classes, feature classes that participate in composite relationships or other relationships with messaging may only be updated within an edit session. If you attempt to use an insert cursor on one of these classes outside of an edit session, it will fail. In addition, inserts of features that participate in a Topology or Geometric Network must be bracketed within an edit operation.

If the insert cursor is created outside of an edit operation and new features are inserted within an edit operation, the changes are commited to the base tables.  The additions to the base table cannot be undone.  For this reason, insert cursors should typically be scoped to edit operations.

When using an insert cursor with simple features, IFeature.Store will not be called when a feature is inserted. If a class extension, editor extension or other custom implementation relies on the messages propagated from the Store method, this could cause a problem. The IObjectClassInfo interface can be implemented by a class extension to force a Store call when an insert cursor is used. Alternately, requiring Store calls can be specified across a workspace by setting the IWorkspaceEditControl.SetStoreEventsRequired property to true.

If the insert cursor is used to insert complex features (such as network features), the cursor will revert to using IFeature.Store.

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.
