Field Summary
final static  CGAlgorithmscga
    
final static  GeometryFactoryfactory
    


Method Summary
public static  GeometryconvertToCollection(Geometry geom, ShapeType type)
    
final public static  ClassfindBestGeometryClass(ShapeType type)
    
final public static  ShapeTypefindBestGeometryType(Geometry geom)
     Determine the best ShapeType for a given Geometry.
Parameters:
  geom - The Geometry to analyze.
final public static  ShapeTypegetShapeType(Geometry geom, int shapeFileDimentions)
     Determine the best ShapeType for a geometry with the given dimension.
Parameters:
  geom - The Geometry to examine.
Parameters:
  shapeFileDimentions - The dimension 2,3 or 4.
throws:
  ShapefileException - If theres a problem, like a bogus Geometry.
final public static  ShapeTypegetShapeType(Class featureClass)
     Determine the default ShapeType for a featureClass.
final public static  intguessCoorinateDims(Coordinate[] cs)
     Returns:
2 for 2d (default)
4 for 3d - one of the oordinates has a non-NaN z value
(3 is for x,y,m but thats not supported yet)

Parameters:
  cs - The array of Coordinates to search.
final public static  MultiPolygonmakeGoodShapeMultiPolygon(MultiPolygon mp)
     Like makeGoodShapePolygon, but applied towards a multi polygon.
Parameters:
  mp - The MultiPolygon to "niceify".
final public static  PolygonmakeGoodShapePolygon(Polygon p)
     Create a nice Polygon from the given Polygon.
final public static  LinearRingreverseRing(LinearRing lr)
     Does what it says, reverses the order of the Coordinates in the ring.
Parameters:
  lr - The ring to reverse.
final public static  double[]zMinMax(Coordinate[] cs)
     Determine the min and max "z" values in an array of Coordinates.
Parameters:
  cs - The array to search.

findBestGeometryClass
final public static Class findBestGeometryClass(ShapeType type)(Code)



findBestGeometryType
final public static ShapeType findBestGeometryType(Geometry geom)(Code)
Determine the best ShapeType for a given Geometry.
Parameters:
  geom - The Geometry to analyze. The best ShapeType for the Geometry.



getShapeType
final public static ShapeType getShapeType(Geometry geom, int shapeFileDimentions) throws ShapefileException(Code)
Determine the best ShapeType for a geometry with the given dimension.
Parameters:
  geom - The Geometry to examine.
Parameters:
  shapeFileDimentions - The dimension 2,3 or 4.
throws:
  ShapefileException - If theres a problem, like a bogus Geometry. The best ShapeType.



getShapeType
final public static ShapeType getShapeType(Class featureClass) throws ShapefileException(Code)
Determine the default ShapeType for a featureClass. Shapetype will be the 2D shapetype.
Parameters:
  featureClass - The Geometry to examine. The best ShapeType.
throws:
  ShapefileException - If theres a problem, like a bogus feature class.



guessCoorinateDims
final public static int guessCoorinateDims(Coordinate[] cs)(Code)
Returns:
2 for 2d (default)
4 for 3d - one of the oordinates has a non-NaN z value
(3 is for x,y,m but thats not supported yet)

Parameters:
  cs - The array of Coordinates to search. The dimension.



makeGoodShapeMultiPolygon
final public static MultiPolygon makeGoodShapeMultiPolygon(MultiPolygon mp)(Code)
Like makeGoodShapePolygon, but applied towards a multi polygon.
Parameters:
  mp - The MultiPolygon to "niceify". The "nicified" MultiPolygon.



makeGoodShapePolygon
final public static Polygon makeGoodShapePolygon(Polygon p)(Code)
Create a nice Polygon from the given Polygon. Will ensure that shells are clockwise and holes are counter-clockwise. Capiche?
Parameters:
  p - The Polygon to make "nice". The "nice" Polygon.



reverseRing
final public static LinearRing reverseRing(LinearRing lr)(Code)
Does what it says, reverses the order of the Coordinates in the ring.
Parameters:
  lr - The ring to reverse. A new ring with the reversed Coordinates.



zMinMax
final public static double[] zMinMax(Coordinate[] cs)(Code)
Determine the min and max "z" values in an array of Coordinates.
Parameters:
  cs - The array to search. An array of size 2, index 0 is min, index 1 is max.
