Classes
class	EdgeSetNoder
	Nodes a set of edges. Takes one or more sets of edges and constructs a new set of edges consisting of all the split edges created by noding the input edges together. More...
class	LineBuilder
	Forms NTS LineStrings out of a the graph of DirectedEdges created by an OverlayOp. More...
class	MaximalEdgeRing
	A ring of edges which may contain nodes of degree > 2. A MaximalEdgeRing may represent two different spatial entities: a single polygon possibly containing inversions (if the ring is oriented CW) a single hole possibly containing exversions (if the ring is oriented CCW) If the MaximalEdgeRing represents a polygon, the interior of the polygon is strongly connected. These are the form of rings used to define polygons under some spatial data models. However, under the OGC SFS model, MinimalEdgeRings are required. A MaximalEdgeRing can be converted to a list of MinimalEdgeRings using the BuildMinimalRings() method. More...
class	MinimalEdgeRing
	A ring of edges with the property that no node has degree greater than 2. These are the form of rings required to represent polygons under the OGC SFS spatial data model. More...
class	OverlayNodeFactory
	Creates nodes for use in the PlanarGraphs constructed during overlay operations. More...
class	OverlayOp
	Computes the geometric overlay of two IGeometrys. The overlay can be used to determine any bool combination of the geometries. More...
class	PointBuilder
	Constructs Points from the nodes of an overlay graph. More...
class	PolygonBuilder
	Forms Polygons out of a graph of {DirectedEdge}s. The edges to use are marked as being in the result Area. More...

Enumerations
enum	SpatialFunction { SpatialFunction.Intersection = 1, SpatialFunction.Union = 2, SpatialFunction.Difference = 3, SpatialFunction.SymDifference = 4 }
	The spatial functions supported by this class. These operations implement various bool combinations of the resultants of the overlay. More...
