public LineSegment(double x1,
 double x2,
 double y1,
 double y2)

Creates a new instance of LineSegment

Method Details

include

public boolean include(double x)

return true if the abscissa x is inside the abscissa interval.

includeAbscissa

public boolean includeAbscissa(LineSegment u)

return true if the all the abscissa of the LineSegment 'v' are included in the abscissa interval.

interpolation

public double interpolation(double x)

compute the linear interpolation of the ordinate for abscissa, x.

isVertical

public boolean isVertical()

return true if the segment is vertical

isParallelTo

public boolean isParallelTo(LineSegment v)

retun true if the segment is parallel to 'v'.

bottomTruncature

public LineSegment bottomTruncature(double x)

return the upper truncature at abscissa, x.

topTruncature

public LineSegment topTruncature(double x)

return the lower truncature at abscissa, x.

integralWith

public double integralWith(LineSegment v,
 int type)

compute a integral based on two LineSegment u and v. u is this LineSegment. v is the LineSegment v. type may be one of the following: 0 : correspond to scalar product u.v. 1 : correspond to area between u and v.
