Detailed Description

FdoTopoGeometryPropertyDefinition derives from FdoGeometricPropertyDefinition, but it has behavior of both geometry and fixed association. It can be used to relate an application-domain feature class (other than a topological primitive class) to a topology. One can use the short form TopoGeometry to refer to these properties. Values of this property can be used:.

• as spatial geometries; use FdoIFeatureReader::GetGeometry().
• to gain access to relationships to underlying features, including topology primitives, similar to Association Properties; e.g. use FdoIFeatureReader::GetObject() to retrieve, and associated feature identifiers to insert/update.
