Detailed Description

The FdoIGeometryCapabilities class delineates available support for raster processing from a provider.

Definition at line 31 of file IGeometryCapabilities.h.

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 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.
