Constructor Details

Polygon2D

public Polygon2D(double startX,
 double startY)

Creates a new polygon starting at the given point. Use lineTo(double, double) to add further corner points.

Parameters:

startX - the x coordinate of the first point

startY - the y coordinate of the first point

Method Details

lineTo

public Polygon2D lineTo(double x,
 double y)

Adds another corner point to the polygon.

Parameters:

x - the x coordinate of the corner to add

y - the y coordinate of the corner to add

Returns:

this instance to support fluent-style construction

contains

public boolean contains(double x,
 double y)

Returns whether the specified point lies inside this shape.

Specified by:

contains in interface Shape2D

Parameters:

x - the x coordinate of the point to test

y - the y coordinate of the point to test

Returns:

true if the point is inside this shape; false otherwise

isEmpty

public boolean isEmpty()

Returns whether this shape is empty.

Specified by:
