geos::operation::valid Namespace Reference

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

Classes
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	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	IndexedNestedShellTester
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...
