Detailed Description

FdoGeometricPropertyDefinition derives from FdoPropertyDefinition and represents a geometric value. Geometric properties can take on any of the geometric types listed in the FdoGeometricType enumeration.

Note:
Geometric properties do not actually store the coordinate system or measure units, this is to enable the use of the same schema in different geometric locals. FdoGeometricType informs the client application what types of geometric primitives it can expect when reading a particular geometric property (and what types they can store in the property on insert/update). The client application can interpret the actual geometry values as it wants, e.g., displaying and manipulating the vertices of a Polyline as a group of independent points.

Public Member Functions

virtual void _writeXml (FdoSchemaXmlContext *pContext)
 Serialize this property to XML.
bool GetAllDefaults ()
 Returns true if none of this property's setters have been called.
FDO_API FdoInt32 GetGeometryTypes ()

FDO_API void SetReadOnly (bool value)
 Sets a Boolean value that specifies whether this geometric property is read-only.
FDO_API void SetSpatialContextAssociation (FdoString *value)
 Sets/add a Spatial Context association to this geometric property.
virtual FdoBoolean XmlEndElement (FdoXmlSaxContext *context, FdoString *uri, FdoString *name, FdoString *qname)
 Element end.
virtual FdoXmlSaxHandler * XmlStartElement (FdoXmlSaxContext *context, FdoString *uri, FdoString *name, FdoString *qname, FdoXmlAttributeCollection *atts)
