Method Summary

ISegmentGraphCursor	getCursor(IPoint p) Returns a SegmentGraphCursor initially located at the segment closest to the specified point.
IEnvelope	getEnvelope() The Envelope of the SegmentGraph.
void	load(IEnumGeometry geometries, boolean generateFaces, boolean takeOwnership) Defines a SegmentGraph from an enumeration of polylines or polygons.
void	setEmpty() Sets the SegmentGraph to the empty state.
