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, Polyline, Polygon, and Multipatch—these are all objects in the Geometry object model. See the GeometryDef object for more details.

Simple features are the most common type of features, but there are various special kinds as defined by the esriFeatureType enumeration. These include annotation, dimension, and various network features. Some feature types - such as Annotation and Dimension features - are implemented using a subclass of this class.

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

store

public void store()
           throws IOException,
                  AutomationException
Stores the row.

Remarks

The Store method is called by an application once it has modified the values of a Row. Once Store is called on a Row object, all subsequent queries within the same edit session, using the Geodatabase API, will reflect the modified state of the Row object.

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.

Calling the Store method triggers the following actions:

- The IRowEvents::OnChanged is called for the row being stored. The OnNew is called if this is a newly created row being stored for the first time. A custom row object can implement the OnChanged method and take some special action when it is called - for example; update a special column in the row

- The IRelatedObjectEvents::RelatedObjectChanged method is called for related objects in a related object class if the table for this row is an object class that participates in relationship classes with notification

Store should not be used for batch operations, such as updates or inserts. For performing a number of inserts or updates using cursors, refer to the ITable::Insert, ITable::Update, ITable::UpdateSearchedRows , IFeatureClass::Update andIFeatureClass::Insert. If an insert or update cursor is used on non-simple features (such as network features), the cursor will revert to using Store.

It is not necessary to explicitly call Connect on network features, this is handled polymorphically when Store is called on the feature. This is also the case with features in a Topology, Dirty Area creation is handled internally when Store is called.

Store should not be called inside of edit events, such as OnCreateFeature, OnChangeFeature or OnDeleteFeature. Even if you are modifying the geometry or other field values, Store will be called once the event is complete.

                              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.

validate

public boolean validate(String[] errorMessage)
                 throws IOException,
                        AutomationException
Validates the row.

Description

The Validate method indicates whether the row is violating any of its class's rules. A return value of true indicates the row is valid, while a return value of false indicates the row is violating one or more rules.

Remarks

Validate on a row occurs in five steps:

  1. Validate the subtype

  2. Validate the attribute rules

  3. Validate the network connectivity rules (if network feature)

  4. Validate the relationship rules

  5. Perform custom validation (using optional class extension)

The validate process stops once a row is found invalid. For example, if a network feature violates an attribute rule, the validation process stops and the feature's network connectivity rules are not evaluated until the attribute rule violation is corrected.

splitWithUpdate

                     throws IOException,
                            AutomationException
Split the feature by updating the split feature and creating new feature(s) for the smaller portion.

Remarks

SplitWithUpdate divides polylines by points or polygons by polylines, other kinds of split geometries are not supported (see IGeometry::GeometryType property for an enumeration of geometry types). Unlike the IFeatureEdit::Split method, SplitWithUpdate does not delete the original feature and insert two new features. When a feature is split, its geometry is modified and a new feature, with a new ObjectID, is inserted comprised of the remaining geometry. The geometry of the original feature will be modified to represent the largest section of the split geometry. For example, if a polyline is split at 60% along its length, the original feature's geometry will be modified to represent the 60% section and a new feature will be created with a geometry representing the remaining 40%.

You can define a policy on how the other attribute values of the new features are populated; this can be done with ArcCatalog or by using the Domain and Attribute Rule objects.

It is not necessary to call SplitAttributes after calling Split, this is done automatically.

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.
