## com.vividsolutions.jts.operation.valid
Class TopologyValidationError

    java.lang.Object
      com.vividsolutions.jts.operation.valid.TopologyValidationError

public class TopologyValidationError
extends java.lang.Object

Contains information about the nature and location of a `Geometry` validation error

Version:
  1.7

Field Summary
`static int` | `DISCONNECTED_INTERIOR` Indicates that the interior of a polygon is disjoint (often caused by set of contiguous holes splitting the polygon into two parts)
`static int` | `DUPLICATE_RINGS` Indicates that a polygonal geometry contains two rings which are identical
`static int` | `ERROR` Deprecated.
`static int` | `HOLE_OUTSIDE_SHELL` Indicates that a hole of a polygon lies partially or completely in the exterior of the shell
`static int` | `INVALID_COORDINATE` Indicates that the `X` or `Y` ordinate of a Coordinate is not a valid numeric value (e.g.
`static int` | `NESTED_HOLES` Indicates that a hole lies in the interior of another hole in the same polygon
`static int` | `NESTED_SHELLS` Indicates that a polygon component of a MultiPolygon lies inside another polygonal component
`static int` | `REPEATED_POINT` Deprecated.
`static int` | `RING_NOT_CLOSED` Indicates that a ring is not correctly closed (the first and the last coordinate are different)
`static int` | `RING_SELF_INTERSECTION` Indicates that a ring self-intersects
`static int` | `SELF_INTERSECTION` Indicates that two rings of a polygonal geometry intersect
`static int` | `TOO_FEW_POINTS` Indicates that either a LineString contains a single point a LinearRing contains 2 or 3 points

Constructor Summary
`TopologyValidationError(int errorType)` Creates a validation error of the given type with a null location
`TopologyValidationError(int errorType, Coordinate pt)` Creates a validation error with the given type and location

Method Summary
`Coordinate` | `getCoordinate()` Returns the location of this error (on the `Geometry` containing the error).
`int` | `getErrorType()` Gets the type of this error.
`java.lang.String` | `getMessage()` Gets an error message describing this error.
`java.lang.String` | `toString()` Gets a message describing the type and location of this error.
