Method Detail

getPoint

public org.eclipse.draw2d.geometry.Point getPoint()

Gets the point

Returns:

the point

getDirection

public Position.Direction getDirection()

Gets the direction

Returns:

the direction

getObstacle

public org.eclipse.draw2d.geometry.Rectangle getObstacle()

Gets the obstacle: the area assigned with figure - source of the ray

Returns:

the obstacle: the area assigned with figure - source of the ray

isHorizontal

public boolean isHorizontal()

Checks, is direction not specified or horizontal

Returns:

true in case direction not specified or horizontal and false otherwise

isVertical

public boolean isVertical()

Checks, is direction not specified or vertical

Returns:

true in case direction not specified or vertical and false otherwise

create

public static Position create(org.eclipse.draw2d.geometry.Rectangle obstacle,
                              org.eclipse.draw2d.geometry.Point point)

Factory method for create new instance of the Position using point and obstacle. Calculates the rectangle side nearest to a point and sets the ray direction to opposite. If obstacle is null then Ray with empty direction will created.

Parameters:

obstacle - the area assigned with figure - source of the ray

point - the point of ray

Returns:

new instance of the Position

getCopy

public Position getCopy()

Returns:

a copy of this Position

moveOnDirection

public Position moveOnDirection(int length)

Shifts the start point by the specified length using the current direction.

Parameters:

length - - a length

Returns:

this for convenience

toString

public String toString()

Returns the string in the format: "(<x>,<y>) <direction>"

Overrides:

toString in class Object
