Constructor Detail

Polygon

public Polygon(List<Point> filledShape)

Constructor that creates a single shape without any holes.

Parameters:

filledShape - a list of points that must form a ring

Polygon

public Polygon(List<Point> filledShape,
               Collection<List<Point>> holes)

Constructor that creates a shape with holes.

Parameters:

filledShape - a list of points that must form a ring, defining the filled shape

holes - a list of rings of coordinates, where each ring defines a hole in the filledShape

Polygon

public Polygon(Collection<List<Point>> shapes)

Constructor that requires a collection of rings. The first ring defines the filled shape and every subsequent ring defines a whole in the filled shape.

Parameters:

shapes - a collection of coordinate rings

Polygon

public Polygon(com.google.gson.JsonArray array)

Constructor that requires a JsonArray of rings. The first ring defines the filled shape and every subsequent ring defines a whole in the filled shape.

Parameters:

array - a JsonArray of coordinate rings

Method Detail

hasHoles

public boolean hasHoles()

Checks if holes exist in the polygon.

Returns:

true, if the polygon has holes in it

getFilledShape

public List<Point> getFilledShape()

Returns the filled shape of the polygon.

Returns:

the filled shape of the polygon

setFilledShape

public void setFilledShape(List<Point> shape)

Changes the filled shape of the polygon witout changing the holes.

Parameters:

shape - a ring of coordinates, defining a shape

getHoles

public List<List<Point>> getHoles()

Returns a list of all holes.

Returns:

a list of rings, defining the holes of the polygon

removeAllHoles

public void removeAllHoles()

Removes all holes of the polygon.
