LineSegment

public LineSegment(T start,
                   T 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 <T> LineSegment<T> startLineSegmentSeries(T p)

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

Type Parameters:

T - the class of the line segment

Parameters:

p - the starting point

Returns:

the starting of a line segment

lineSegmentSeries

public static <T> List<LineSegment<T>> lineSegmentSeries(List<T> coords)

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

Type Parameters:

T - the class of the line segment

Parameters:

coords - the list of points

Returns:

the list of segments

getStart

public T getStart()

Returns with the start point of the segment.

Returns:

the start point of the segment

getEnd

public T getEnd()

Returns with the end point of the segment.

Returns:

the end point of the segment

next

public LineSegment<T> next(T c)

Creates the next segment of the line segment series.

Parameters:

c - the next point of the point series

Returns:

the next segment of the line segment series

contains

public boolean contains(T c)

Checks if the given coordinate is equals with either end point of this segment.

Parameters:

c - the point to be checked

Returns:

true if and only if either of the two end points of this segment is equals with the given point

hasCommon

public boolean hasCommon(LineSegment<T> ls)

Checks if this segment and the given segment has a common end point.

Parameters:

ls - the other segment to be checked

Returns:

true if and only if this segment and the given segment has a common end point

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
