Cgeos::operation::valid::SweeplineNestedRingTester | Tests whether any of a set of LinearRings are nested inside another ring in the set, using an SweepLineIndex to speed up the comparisons |
Cgeos::simplify::TaggedLinesSimplifier | Simplifies a collection of TaggedLineStrings, preserving topology (in the sense that no new intersections are introduced) |
Cgeos::simplify::TaggedLineString | Contains and owns a list of TaggedLineSegments |
Cgeos::simplify::TaggedLineStringSimplifier | Simplifies a TaggedLineString, preserving topology (in the sense that no new intersections are introduced). Uses the recursive Douglas-Peucker algorithm |
Cgeos::geomgraph::TopologyLocation | A TopologyLocation is the labelling of a GraphComponent's topological relationship to a single Geometry |
Cgeos::simplify::TopologyPreservingSimplifier | Simplifies a geometry, ensuring that the result is a valid geometry having the same dimension and number of components as the input |
Cgeos::operation::valid::TopologyValidationError | Contains information about the nature and location of a geom::Geometry validation error |
