Subgraph	A subgraph of a PlanarGraph.
SweepLineEvent
SweepLineEvent
SweepLineIndex	A sweepline implements a sorted index on a set of intervals.
SweepLineInterval
SweepLineOverlapAction	An action taken when a SweepLineIndex detects that two SweepLineIntervals overlap
SweepLineSegment
TaggedLineStringSimplifier	Simplifies a TaggedLineString, preserving topology (in the sense that no new intersections are introduced).
TopologyException	Indicates an invalid or inconsistent topological situation encountered during processing
TopologyLocation	A TopologyLocation is the labelling of a GraphComponent's topological relationship to a single Geometry.
TopologyPreservingSimplifier	Simplifies a geometry and ensures that the result is a valid geometry having the same dimension and number of components as the input, and with the components having the same topological relationship.
TopologyValidationError	Contains information about the nature and location of a Geometry validation error
TraversalVisitor	Interface for classes which process triangles visited during traversals of a QuadEdgeSubdivision
Triangle	Represents a planar triangle, and provides methods for calculating various properties of triangles.
TrianglePredicate	Algorithms for computing values and predicates associated with triangles.
TriangleVisitor	An interface for algorithms which process the triangles in a QuadEdgeSubdivision.
UnaryUnionOp	Unions a Collection of Geometrys or a single Geometry (which may be a GeoometryCollection) together.
UnionInteracting	Experimental code to union MultiPolygons with processing limited to the elements which actually interact.
UniqueCoordinateArrayFilter	A CoordinateFilter that builds a set of Coordinates.
VariableWidthBuffer	Creates a buffer polygon with variable width along a line.
Vector2D	A 2-dimensional mathematical vector represented by double-precision X and Y components.
Vector3D	Represents a vector in 3-dimensional Cartesian space.
Vertex	Models a site (node) in a QuadEdgeSubdivision.
VertexTaggedGeometryDataMapper	Creates a map between the vertex Coordinates of a set of Geometrys, and the parent geometry, and transfers the source geometry data objects to geometry components tagged with the coordinates.
VoronoiDiagramBuilder	A utility class which creates Voronoi Diagrams from collections of points.
VWSimplifier	Simplifies a Geometry using the Visvalingam-Whyatt area-based algorithm.
WKBConstants	Constant values used by the WKB format
WKBHexFileReader	Reads a sequence of Geometrys in WKBHex format from a text file.
WKBReader	Reads a Geometryfrom a byte stream in Well-Known Binary format.
WKBWriter	Writes a Geometry into Well-Known Binary format.
WKTFileReader	Reads a sequence of Geometrys in WKT format from a text file.
WKTReader	Converts a geometry in Well-Known Text format to a Geometry.
WKTWriter	Writes the Well-Known Text representation of a Geometry.
