public Segment(double x1, double y1, double z1, double x2, double y2, double z2)
Creates a new instance for the given ordinates.
public Segment(double x1, double y1, double z1, double x2, double y2, double z2, Object data)
Creates a new instance for the given ordinates, with associated external data.
public Segment(Coordinate p0, Coordinate p1, Object data)
Creates a new instance for the given points, with associated external data.
Parameters:
p0 - p0 the start point
p1 - p1 the end point
data - data an external data object
public Segment(Coordinate p0, Coordinate p1)
Creates a new instance for the given points.
Parameters:
p0 - p0 the start point
p1 - p1 the end point
public Coordinate getStart()
Gets the start coordinate of the segment
Returns:
a Coordinate
public Coordinate getEnd()
Gets the end coordinate of the segment
Returns:
a Coordinate
public double getStartX()
Gets the start X ordinate of the segment
Returns:
the X ordinate value
public double getStartY()
Gets the start Y ordinate of the segment
Returns:
the Y ordinate value
public double getStartZ()

public boolean equalsTopo(Segment s)
Determines whether two segments are topologically equal. I.e. equal up to orientation.
Parameters:
s - s a segment
Returns:
true if the segments are topologically equal
public Coordinate intersection(Segment s)
Computes the intersection point between this segment and another one.
Parameters:
s - s a segment
Returns:
the intersection point, or null if there is none
public String toString()
Computes a string representation of this segment.
Returns:
a string
