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 FdoGeometryComponentType * | GetGeometryComponentTypes (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 FdoGeometryType * | GetGeometryTypes (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. |
