Field Detail

drawColor

public java.awt.Color drawColor

The drawing color of the line string.

Constructor Detail

LineString

public LineString(java.awt.Color dc)

Builds and initializes a line string with no point at the beginning.

Parameters:

dc - the drawing color.

LineString

public LineString()

Builds and initializes a line string with a default drawing color (light gray).

Method Detail

draw

public void draw(java.awt.Graphics2D g2d,
        CoordinateConverter converter)

Description copied from interface: GraphicalPrimitive

The function that draws the primitive

Specified by:

draw in interface GraphicalPrimitive

Parameters:

g2d - the Graphics2D object on which the shape must be drawn.

converter - the coordinate converter used to convert the primitive's coordinates into the screen (hence Graphics2D) coordinates.

addPoint

public void addPoint(Point p)

Adds a point at the end of the line string.

Parameters:

p - the point to be added.

iterator

public java.util.Iterator<Point> iterator()

Gets an iterator over the points of the line string.

Specified by:

iterator in interface java.lang.Iterable<Point>

Returns:

an iterator over the points.

getBoundingBox

public BoundingBox getBoundingBox()

Description copied from interface: GraphicalPrimitive

Computes the bounding box of the graphical primitive.

Specified by:

getBoundingBox in interface GraphicalPrimitive

Returns:

the bounding box of the primitive.
