Classes
class	CascadedPolygonUnion
	Provides an efficient method of unioning a collection of polygonal geometries. More...
class	ClassicUnionStrategy
	Implementation of UnionStrategy that provides overlay using the first generation overlay routines. More...
class	OverlapUnion
	Unions MultiPolygons efficiently by using full topological union only for polygons which may overlap by virtue of intersecting the common area of the inputs. More...
class	PointGeometryUnion
	Computes the union of a puntal geometry with another arbitrary Geometry. More...
class	UnaryUnionOp
	Unions a collection of Geometry or a single Geometry (which may be a collection) together. More...
class	UnionStrategy
