Constructor Detail

Highway

protected Highway(int start,
                  int end,
                  int position,
                  boolean type)

Constructor

Parameters:

start - the start position. x in case horizontal or y otherwise

end - the end position. x in case horizontal or y otherwise

position - the y position in case horizontal or x otherwise

type - true - horizontal, false vertical

Method Detail

createHorizontal

public static Highway createHorizontal(int x,
                                       int y,
                                       int length)

Static factory method creting horizontal Highway using point and length. Use Integer.MIN_VALUE and Integer.MAX_VALUE foor creating unlimited end.

Examples:
createHorizontal(-100, 100, 200):
line segment [point(-100, 100), point(100, 100)]
createHorizontal(Integer.MIN_VALUE, 100, 200-Integer.MIN_VALUE):
line segment [point(-INFINITY, 200), point(100, 200)]
createHorizontal(-200, 100, Integer.MAX_VALUE-(-200)):
line segment [point(-200, 100), point(INFINITY, 200)]

Parameters:

x - - x coordinate of the point

y - - y coordinate of the point

length - - length

Returns:

horizontal Highway

createVertical

public static Highway createVertical(int x,
                                     int y,
                                     int length)

Static factory method creting vertival Highway using point and length. Use Integer.MIN_VALUE and Integer.MAX_VALUE foor creating unlimited end.

Examples:
createVertical(-100, 100, 200):
line segment [point(-100, 100), point(-100, 300)]
createVertical(100, Integer.MIN_VALUE, 200-Integer.MIN_VALUE):
line segment [point(100, -INFINITY), point(100, 200)]
createVertical(-200, -100, Integer.MAX_VALUE-(-100)):
line segment [point(-200, -100), point(-200, INFINITY)]

Parameters:

x - - x coordinate of the point

y - - y coordinate of the point

length - - length

Returns:

horizontal Highway

getStart

the y position in case horizontal or x otherwise

isHorizontal

public boolean isHorizontal()

Whether is horisontal highway?

Returns:
