Field Detail
ARC
final public static int ARC(Code)
Creates polygons whose points will not be rectangular when there are more than 4 points



BOX
final public static int BOX(Code)
Creates rectangular polygons



generationAlgorithm
protected int generationAlgorithm(Code)



numberHoles
protected int numberHoles(Code)



numberPoints
protected int numberPoints(Code)





Method Detail
create
public Geometry create()(Code)
As the user increases the number of points, the probability of creating a random valid polygon decreases. Please take not of this when selecting the generation style, and the number of points. May return null if a geometry could not be created.

throws:
  IllegalStateException - When the alg is not valid or the number of points is invalid
throws:
  NullPointerException - when either the Geometry Factory, or the Bounding Box are undefined.



getGenerationAlgorithm
public int getGenerationAlgorithm()(Code)
Returns the generationAlgorithm.



getNumberHoles
public int getNumberHoles()(Code)
