Returns the angle of the Ground WRT the x axis in radians.

Specified by:

getAngle in interface Rotatable

paint

public void paint()

Draw the Ground

Specified by:

paint in interface Paintable

paint

public void paint(Graphics g)

Draw the Ground

Specified by:

paint in interface Paintable

public void paintOriginal(Graphics g)

This method is used to paint the original data points that forms this GeometricObject

Specified by:

paintOriginal in interface Paintable

setGraphicsContext

public void setGraphicsContext(Graphics g)

Set graphics context for this Ground object. Must be set at least once before doing any drawing.

Specified by:

setGraphicsContext in interface Paintable

getType

public String getType()

Implement Paintable

Specified by:

getType in interface Paintable

getRectangularBounds

public Rectangle getRectangularBounds()

This method should return the Rectangular bounds of this non-terminal object.

Specified by:

getRectangularBounds in interface NonTerminal

getPolygonalBoundsArray
