dataset

[out] Address of a variable that receives the pointer to the IFeatureDataset interface associated with the feature dataset.

Returns

kSDKResult_Succeeded

kSDKResult_NotImplemented

GetShape()

virtual GDBResult SDK_CALLTYPE GetShape ( geometry::IGeometry **  shape ) throw ( )

pure virtual

Returns a reference to the default shape for the feature.

Parameters
