        public Subpath()
        Creates a new SubPath instance.

      • Subpath

        public Subpath​(Subpath subpath)
        Copy constructor.
        Parameters:
        subpath - Subpath which contents will be used to create this Subpath

      • Subpath

        public Subpath​(Point startPoint)
        Constructs a new subpath starting at the given point.
        Parameters:
        startPoint - the point this subpath starts at

      • Subpath

        public Subpath​(float startPointX,
               float startPointY)
        Constructs a new subpath starting at the given point.
        Parameters:
        startPointX - x-coordinate of the start point of subpath
        startPointY - y-coordinate of the start point of subpath

    • Method Detail

      • setStartPoint

        public void setStartPoint​(Point startPoint)
        Sets the start point of the subpath.
        Parameters:
        startPoint - the point this subpath starts at

      • setStartPoint

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

      • getStartPoint

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

      • getLastPoint

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

      • addSegment

        public void addSegment​(IShape 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<IShape> 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()
        Returns:
        true if this subpath contains only one point and it is closed, false otherwise

      • 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.

      • setClosed

        public void setClosed​(boolean closed)
        See isClosed()
        Parameters:
        closed - boolean value indicating whether the path is closed or not.

      • 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.

      • getPiecewiseLinearApproximation

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