Method Detail

create

public static Oval create(double minX,
                          double minY,
                          double width,
                          double height,
                          CoordinateReferenceSystem crs)

Creates a new Oval object.

Parameters:

minX - the min X ordinate

minY - the min Y ordinate

width - the width

height - the height

crs - the coordinate reference system (may be null)

Returns:

a new Oval object

Throws:

IllegalArgumentException - if either width or height are <= 0

createGrid

public static SimpleFeatureSource createGrid(ReferencedEnvelope bounds,
                                             double width,
                                             double height,
                                             GridFeatureBuilder gridBuilder)

Creates a new grid of oblongs within a bounding rectangle with grid elements represented by simple (ie. undensified) polygons.

Parameters:

bounds - the bounding rectangle

width - oblong width

height - oblong height

gridBuilder - an instance of GridFeatureBuilder

Returns:

a new grid

Throws:

IllegalArgumentException - if bounds is null or empty; or if either width or height is <= 0; or if the CoordinateReferenceSystems set for the bounds and the GridFeatureBuilder are both non-null but different

createGrid

public static SimpleFeatureSource createGrid(ReferencedEnvelope bounds,
                                             double width,
                                             double height,
                                             double vertexSpacing,
                                             GridFeatureBuilder gridFeatureBuilder)

Creates a new grid of oblongs within a bounding rectangle with grid elements represented by densified polygons (ie. additional vertices added to each edge).

Parameters:

bounds - the bounding rectangle

width - oblong width

height - oblong height

vertexSpacing - maximum distance between adjacent vertices in a grid element; if <= 0 or >= min(width, height) / 2.0 it is ignored and the polygons will not be densified

gridFeatureBuilder - an instance of GridFeatureBuilder

Returns:

the vector grid

Throws:

IllegalArgumentException - if bounds is null or empty; or if either width or height is <= 0; or if the CoordinateReferenceSystems set for the bounds and the GridFeatureBuilder are both non-null but different
