        public Subpath​(Subpath subpath)
        Copy constuctor.
        Parameters:

      • Subpath

        public Subpath​(Point2D startPoint)
        Constructs a new subpath starting at the given point.

    • Method Detail

      • setStartPoint

        public void setStartPoint​(Point2D startPoint)
        Sets the start point of the subpath.
        Parameters:
        startPoint -

      • setStartPoint

        public void setStartPoint​(float x,
                          float y)
        Sets the start point of the subpath.
        Parameters:
        x -
        y -

      • getStartPoint

        public Point2D getStartPoint()
        Returns:
        The point this subpath starts at.

      • getLastPoint

        public Point2D getLastPoint()
        Returns:
        The last point of the subpath.

      • addSegment

        public void addSegment​(Shape segment)
        Adds a segment to the subpath. Note: each new segment shall start at the end of the previous segment.
        Parameters:
        segment - new segment.

      • getSegments

        public java.util.List<Shape> getSegments()
        Returns:
        List comprising all the segments the subpath made on.

      • isEmpty

        public boolean isEmpty()
        Checks whether subpath is empty or not.
        Returns:
        true if the subpath is empty, false otherwise.

      • isSinglePointOpen

        public boolean isSinglePointOpen()
        Returns:
        true if this subpath contains only one point and it is not closed, false otherwise

      • isSinglePointClosed

        public boolean isSinglePointClosed()

      • isClosed

        public boolean isClosed()
        Returns a boolean value indicating whether the subpath must be closed or not. Ignore this value if the subpath is a rectangle because in this case it is already closed (of course if you paint the path using re operator)
        Returns:
        boolean value indicating whether the path must be closed or not.
        Since:
        5.5.6

      • setClosed

        public void setClosed​(boolean closed)
        See isClosed()

      • isDegenerate

        public boolean isDegenerate()
        Returns a boolean indicating whether the subpath is degenerate or not. A degenerate subpath is the subpath consisting of a single-point closed path or of two or more points at the same coordinates.
        Returns:
        boolean value indicating whether the path is degenerate or not.
        Since:
        5.5.6

      • getPiecewiseLinearApproximation

        public java.util.List<Point2D> getPiecewiseLinearApproximation()
        Returns:
        List containing points of piecewise linear approximation for this subpath.
