geos::operation::valid Namespace Reference

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

Classes

class  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  ConnectedInteriorTester
 This class tests that the interior of an area Geometry (Polygon or MultiPolygon) is connected. More...
 
class  ConsistentAreaTester
 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  IsValidOp
 Implements the algorithsm required to compute the isValid() method for Geometrys. More...
 
class  MakeValid
 The function attempts to create a valid representation of a given invalid geometry without losing any of the input vertices. More...
 
class  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  RepeatedPointRemover
 Removes repeated, consecutive equal, coordinates from a CoordinateSequence. More...
 
class  RepeatedPointTester
 Implements the appropriate checks for repeated points (consecutive identical coordinates) as defined in the JTS spec. More...
 
class  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  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. More...
 
class  TopologyValidationError
 Contains information about the nature and location of a geom::Geometry validation error. More...
