static boolean	s2FindValidationError(Geography geog, com.google.common.geometry.S2Error error)	Master dispatch for any Geography type: points, lines, polygons, or collections.
static boolean	s2FindValidationError(PolygonGeography geog, com.google.common.geometry.S2Error error)	Runs S2 validation on a PolygonGeography.
static boolean	s2FindValidationError(PolylineGeography geog, com.google.common.geometry.S2Error error)	Runs S2 validation on a PolylineGeography, writing into the provided S2Error and returning true if an error was found.

Method Details

S2_isEmpty

public static boolean S2_isEmpty(Geography geography)

S2_isCollection

public static boolean S2_isCollection(PolygonGeography polygonGeography)

S2_isCollection

public boolean S2_isCollection(Geography geog)

Returns true if `geog` is a “collection” (i.e. multi‐point, multi‐linestring, or multi‐polygon) rather than a single simple feature.

S2_dimension

public static int S2_dimension(Geography geography)

S2_numPoints

public static int S2_numPoints(Geography geography)

S2_area

public double S2_area(GeographyCollection geographyCollection)

s2_length

public double s2_length(Geography geog)

s2_perimeter

public double s2_perimeter(Geography geog)

s2_X

public static double s2_X(Geography geog)

s2_Y

public static double s2_Y(Geography geog)

Extract the Y coordinate (latitude in degrees) if this is exactly one point; otherwise returns NaN.

s2FindValidationError

public static boolean s2FindValidationError(PolylineGeography geog,
 com.google.common.geometry.S2Error error)

Runs S2 validation on a PolylineGeography, writing into the provided S2Error and returning true if an error was found.

s2FindValidationError

public static boolean s2FindValidationError(PolygonGeography geog,
 com.google.common.geometry.S2Error error)

Runs S2 validation on a PolygonGeography.

s2FindValidationError

public static boolean s2FindValidationError(GeographyCollection geog,
 com.google.common.geometry.S2Error error)

Runs S2 validation on each member of a GeographyCollection.

s2FindValidationError

public static boolean s2FindValidationError(Geography geog,
 com.google.common.geometry.S2Error error)

Master dispatch for any Geography type: points, lines, polygons, or collections. Follows your C++ logic: 0-dim → always OK 1-dim → polyline path 2-dim → polygon path else → treat as collection of polygons
