AddFeatures Method

Adds features to a repository feature layer.

Availability: Business Analyst Server 9.3.1 SP1.

bool AddFeatures ( 
    AddFeaturesParameters  Parameters
);

Parameter Description
Parameters Configuration options for the utility. Type AddFeaturesParameters.

Returns

Variable of type Boolean whose value is always true.

Remarks

This method allows user to add features to a feature layer having a point or polygon geometry. The SourceLayer and DestinationItem layers should have the same type of geometry and the same spatial reference.

While adding features to the destination layer, alien attributes of features are ignored. If the destination layer contains attributes that are missing in the source layer, its values for added features are initialized to default values.

When added to the destination layer, features of the source layer receive serial values for the Object ID attribute starting after the last feature Object ID in the destination layer. Since Object ID attribute value is automatically assigned to new features of the destination layer, it has no sence to specify the Object ID attribute for features of the source feature layer. If this attribute is specified, it is ignored.

NOTE: The name of the Object ID attribute of features depends on a feature class workspace type used. Typical names for Object ID are "FID", "OID", or "OBJECTID".

Examples

The example below creates a store feature layer in the repository by geocoding store address records and adds more store feature records into this layer.

NOTE: The signature of the BAServerHelper.AddFeatures method is modified against this method—a source feature record set and an output folder item are passed in parameters instead of AddFeaturesParameters type.
