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... | |
