public class Subpath extends Object
As subpath is a part of a path comprising a sequence of connected segments.
  • Constructor Details

    • Subpath

      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 Details

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