Public Member Functions

virtual FDO_GEOM_API FdoInt32 GetCount () const =0
 Gets the number of positions in this object.
virtual FDO_GEOM_API FdoIDirectPosition * GetItem (FdoInt32 index) const =0
 Gets the position at the specified (zero-based) index.
virtual FDO_GEOM_API void GetItemByMembers (FdoInt32 index, double *x, double *y, double *z, double *m, FdoInt32 *dimensionality) const =0
 Gets the position at the specified (zero-based) index, by values of its member data. This is in aid of higher performance for any implementation that does not internally use FdoIDirectPosition objects for storage, or for an application seeking to avoid overhead of accessor methods.
virtual FDO_GEOM_API const
double * 		GetOrdinates ()=0
 Gets the ordinates as an array.
virtual FDO_GEOM_API FdoDirectPositionCollection * GetPositions ()=0
 Gets a collection of all of the positions in this object.
