    • finalize

      protected void finalize()
      Overrides:
      finalize in class Curve

    • close

      public void close()
      Specified by:
      close in interface AutoCloseable
      Overrides:

    • getStartPoint

      @NotNull public Coordinate getStartPoint()
      Returns the start point of this arc.
      Returns:
      the start point of this arc.

    • getEndPoint

      @NotNull public Coordinate getEndPoint()
      Returns the end point of this arc.
      Returns:
      the end point of this arc.

    • getBulge

      public double getBulge()
      Returns the bulge factor of this arc.

      The bulge factor is the ratio of (1) the distance between the arc midpoint and the center of the arc's chord, and (2) half the length of the arc's chord. The sign of the bulge indicates whether the midpoint is on the left side (positive) or right side (negative) of the vector from start to end point. So a bulge factor with an absolute value of 1 means a half-circle, smaller than 1 means a less bulging arc and larger than 1 means an arc that bulges out in the start and end point.

      Returns:
      the bulge factor of this arc.
