Public Member Functions

virtual FDO_API FdoInt32 GetDimensionalities ()=0
 Returns the supported dimensionalities which are based on the bit masks defined in the FdoDimensionality enum. The Z and M bits indicate if the provider supports 3d or Measure dimensions in geometry data. The XY bit should be set too.
virtual FDO_API FdoGeometryComponentTypeGetGeometryComponentTypes (FdoInt32 &length)=0
 Return the list of supported component types. For example, if a client wanted to know if circular arcs were supported by a provider, it would call GetGeometryComponentTypes and check for CircularArcSegment in the returned list.
virtual FDO_API FdoGeometryTypeGetGeometryTypes (FdoInt32 &length)=0
 Return the list of supported geometry types. For example, if a client wanted to know if a provider supported multi-polygons, it would call GetGeometryTypes and check if the MultiPolygon type was listed.

virtual FDO_API FdoInt32 FdoIGeometryCapabilities::GetDimensionalities  )  [pure virtual]
 

Returns the supported dimensionalities which are based on the bit masks defined in the FdoDimensionality enum. The Z and M bits indicate if the provider supports 3d or Measure dimensions in geometry data. The XY bit should be set too.

Returns:
Returns the dimensionalities

virtual FDO_API FdoGeometryComponentType* FdoIGeometryCapabilities::GetGeometryComponentTypes FdoInt32 length  )  [pure virtual]
 

Return the list of supported component types. For example, if a client wanted to know if circular arcs were supported by a provider, it would call GetGeometryComponentTypes and check for CircularArcSegment in the returned list.

Parameters:
length Output the number of component types.
Returns:
Returns the list of component types

virtual FDO_API FdoGeometryType* FdoIGeometryCapabilities::GetGeometryTypes FdoInt32 length  )  [pure virtual]
 

Return the list of supported geometry types. For example, if a client wanted to know if a provider supported multi-polygons, it would call GetGeometryTypes and check if the MultiPolygon type was listed.

Parameters:
length Output the number of geometry types.
Returns:
Returns the list of geometry types
