Class LineSegment

  • public class LineSegment
extends java.lang.Object
    Represents a line segment in a particular coordinate system. This class is immutable.

    • Field Detail

      • startPoint

        private final Vector startPoint
        Start vector of the segment.

      • endPoint

        private final Vector endPoint
        End vector of the segment.

    • Constructor Detail

      • LineSegment

        public LineSegment​(Vector startPoint,
                   Vector endPoint)
        Creates a new line segment.
        Parameters:
        startPoint - the start point of a line segment.
        endPoint - the end point of a line segment.

    • Method Detail

      • getStartPoint

        public Vector getStartPoint()
        Returns:
        the start point

      • getEndPoint

        public Vector getEndPoint()
        Returns:
        the end point

      • getLength

        public float getLength()
        Returns:
        the length of this line segment

      • getBoundingRectangle

        public Rectangle getBoundingRectangle()
        Computes the bounding rectangle for this line segment. The rectangle has a rotation 0 degrees with respect to the coordinate system that the line system is in. For example, if a line segment is 5 unit long and sits at a 37 degree angle from horizontal, the bounding rectangle will have origin of the lower left hand end point of the segment, with width = 4 and height = 3.
        Returns:
        the bounding rectangle

      • transformBy

        public LineSegment transformBy​(Matrix m)
        Transforms the segment by the specified matrix
        Parameters:
        m - the matrix for the transformation
        Returns:
        the transformed segment

      • containsSegment

        public boolean containsSegment​(LineSegment other)
        Checks if a segment contains another segment in itself
        Parameters:
        other - a segment to be checked
        Returns:
        true if this segment contains other one, false otherwise

      • containsPoint

        public boolean containsPoint​(Vector point)
        Checks if a segment contains a given point in itself
        Parameters:
        point - a point to be checked
        Returns:
        true if this segment contains given point, false otherwise
