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 Polygon or MultiPolygon ) is consistent with the OGC-SFS semantics for area geometries. 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 | IsValidOp |
Implements the algorithsm required to compute the isValid() method for Geometrys. 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 | 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 index::sweepline::SweepLineIndex to speed up the comparisons. More... | |
class | TopologyValidationError |
Contains information about the nature and location of a Geometry validation error. More... | |
