class  CascadedUnion
 Provides an efficient method of unioning a collection of Geometries. More...
 
class  ClassicUnionStrategy
 Implementation of UnionStrategy that provides overlay using the first generation overlay routines. More...
 
class  GeometryListHolder
 Helper class holding Geometries, part of which are held by reference others are held exclusively. 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
