Constructor Detail

• Arc

  public Arc(double lower,
     double upper,
     double tolerance)
      throws NumberIsTooLargeException

  Simple constructor.

  If either lower is equals to upper or the interval exceeds \( 2 \pi \), the arc is considered to be the full circle and its initial defining boundaries will be forgotten. lower is not allowed to be greater than upper (an exception is thrown in this case). lower will be canonicalized between 0 and \( 2 \pi \), and upper shifted accordingly, so the getInf() and getSup() may not return the value used at instance construction.

  Parameters:

  lower - lower angular bound of the arc

  upper - upper angular bound of the arc

  tolerance - tolerance below which angles are considered identical

  Throws:

  NumberIsTooLargeException - if lower is greater than upper

Method Detail

• getInf

  public double getInf()

  Get the lower angular bound of the arc.

  Returns:

  lower angular bound of the arc, always between 0 and \( 2 \pi \)

• getSup

  public double getSup()

  Get the upper angular bound of the arc.

  Returns:

  upper angular bound of the arc, always between getInf() and getInf() \( + 2 \pi \)

• getSize

  public double getSize()

  Get the angular size of the arc.

  Returns:

  angular size of the arc

• getBarycenter

  public double getBarycenter()

  Get the barycenter of the arc.

  Returns:

  barycenter of the arc

• getTolerance

  public double getTolerance()

  Get the tolerance below which angles are considered identical.

  Returns:

  tolerance below which angles are considered identical

• checkPoint

  public Region.Location checkPoint(double point)

  Check a point with respect to the arc.

  Parameters:

  point - point to check

  Returns:

  a code representing the point status: either Region.Location.INSIDE, Region.Location.OUTSIDE or Region.Location.BOUNDARY
