Field Summary

Fields

Modifier and Type	Field and Description
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 String[]	errMsg Messages corresponding to error codes
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
