Method Detail

getPoint

public final Point getPoint(int index)

Get the Point at index.

getPointX

public final double getPointX(int index)

Get the X Coordinate of the Point at index.

getPointY

public final double getPointY(int index)

Get the X Coordinate of the Point at index.

fastGetX

public abstract double fastGetX(int index)

Get the X coordinate of the Point at index.

WARNING: this method assumes that index is positive and less than size().

fastGetY

public abstract double fastGetY(int index)

Get the Y coordinate of the Point at index.

WARNING: this method assumes that index is positive and less than size().

size

public abstract int size()

Return the number of vertices in this polygon.

intersects

public boolean intersects(Rectangle box,
                          Shape other)

Check if this shape intersects with other.

Specified by:

intersects in class Shape

Parameters:

box - The bounding box of this shape from Shape.getBoundingBox().

other - The shape to check for intersection with

intersects

protected final boolean intersects(Rectangle box,
                                   AbstractPolygon poly)

Check for intersection with poly.

Parameters:

box - This polygon's bounding box

poly - Polygon to check intersection with.

lineIntersects

public abstract boolean lineIntersects(double x1,
                                       double y1,
                                       double x2,
                                       double y2)

Check if the line (x1, y1), (x2, y2) intersects with this polygon.
