Constructor Detail

LineSegment2d

public LineSegment2d(Coords2d start,
                     Coords2d end)

Creates a new line segment using the two given end points.

Parameters:

start - the starting point of the segment

end - the end point of the segment

Method Detail

startLineSegmentSeries

public static LineSegment2d startLineSegmentSeries(Coords2d p)

Starts a series of line segments. You can get the next segment by calling the next method. You can use the LineSegment.lineSegmentSeries(List) method to convert a list of coordinates to a list of line segments.

Parameters:

p - the starting point

Returns:

the starting of a line segment

lineSegmentSeries2d

public static List<LineSegment2d> lineSegmentSeries2d(List<Coords2d> coords)

Returns with the list of line segments which is denoted by this series of points.

Parameters:

coords - the list of points

Returns:

the list of segments

next

public LineSegment2d next(Coords2d c)

Description copied from class: LineSegment

Creates the next segment of the line segment series.

Overrides:

next in class LineSegment<Coords2d>

Parameters:

c - the next point of the point series

Returns:

the next segment of the line segment series

isParallel

public boolean isParallel(LineSegment2d ls)

Checks if the two line segments are parallel.

Parameters:

ls - the other line segment

Returns:

true if and only if the two line segments are parallel

isOnLineSegment

public boolean isOnLineSegment(Coords2d c)

Return true if the given point is on the segment.

Parameters:

c - the point to be checked

Returns:

true if and only if the point is on the line segment

common

public LineSegment2d common(LineSegment2d lc)

Calculates the common part of the two line segments if there are any. Returns null if the two line segments are distinct.

Parameters:

lc - the other line segment

Returns:

the common part or null if they are distinct segments
