geos::operation::valid Namespace Reference

Provides classes for testing the validity of geometries. More...


Classes

class  geos::operation::valid::IndexedNestedRingTester
 Tests whether any of a set of LinearRings are nested inside another ring in the set, using a spatial index to speed up the comparisons. More...
class  geos::operation::valid::ConnectedInteriorTester
 This class tests that the interior of an area Geometry (Polygon or MultiPolygon) is connected. More...
class  geos::operation::valid::ConsistentAreaTester
 Checks that a geomgraph::GeometryGraph representing an area (a Polygon or MultiPolygon ) is consistent with the OGC-SFS semantics for area geometries. Checks that a geomgraph::GeometryGraph representing an area (a geom::Polygon or geom::MultiPolygon) has consistent semantics for area geometries. This check is required for any reasonable polygonal model (including the OGC-SFS model, as well as models which allow ring self-intersection at single points). More...
class  geos::operation::valid::IsValidOp
 Implements the algorithsm required to compute the isValid() method for Geometrys. More...
class  geos::operation::valid::QuadtreeNestedRingTester
 Tests whether any of a set of LinearRings are nested inside another ring in the set, using a Quadtree index to speed up the comparisons. More...
class  geos::operation::valid::RepeatedPointTester
 Implements the appropriate checks for repeated points (consecutive identical coordinates) as defined in the JTS spec. More...
class  geos::operation::valid::SimpleNestedRingTester
 Tests whether any of a set of LinearRings are nested inside another ring in the set, using a simple O(n^2) comparison. More...
class  geos::operation::valid::SweeplineNestedRingTester
 Tests whether any of a set of LinearRings are nested inside another ring in the set, using an index::sweepline::SweepLineIndex to speed up the comparisons. More...
class  geos::operation::valid::TopologyValidationError
 Contains information about the nature and location of a Geometry validation error. More...
