    • Subpath

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

    • Subpath

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

      Constructs a new subpath starting at the given point.

  • Method Details

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