Description

Class Summary
ConnectedInteriorTester: This class tests that the interior of an area `Geometry` ( `Polygon` or `MultiPolygon` ) is connected.
ConsistentAreaTester: Checks that a `GeometryGraph` representing an area (a `Polygon` or `MultiPolygon` ) has consistent semantics for area geometries.
IsValidOp: Implements the algorithsm required to compute the `isValid()` method for `Geometry`s.
QuadtreeNestedRingTester: Tests whether any of a set of `LinearRing`s are nested inside another ring in the set, using a `Quadtree` index to speed up the comparisons.
RepeatedPointTester: Implements the appropriate checks for repeated points (consecutive identical coordinates) as defined in the JTS spec.
SimpleNestedRingTester: Tests whether any of a set of `LinearRing`s are nested inside another ring in the set, using a simple O(n^2) comparison.
SweeplineNestedRingTester: Tests whether any of a set of `LinearRing`s are nested inside another ring in the set, using a `SweepLineIndex` index to speed up the comparisons.
TopologyValidationError: Contains information about the nature and location of a `Geometry` validation error
