Enum Constant Detail

• EUCLID

  public static final Chart2D.PointFinder EUCLID

  Uses the Manhattan distance to find the nearest point.

  This implementation is slower than MANHATTAN but has a search field in form of a circle which is more natural for human eyes.

  See Also:

  Chart2D.getNearestPointEuclid(int, int)

• MANHATTAN

  public static final Chart2D.PointFinder MANHATTAN

  Uses the Manhattan distance to find the nearest point.

  This implementation is faster than EUCLID (only subtractions/additions/abs) but has a search field in form of a rhombus which may confuse human eyes.

  See Also:

  Chart2D.getNearestPointManhattan(int, int)

Method Detail

• values

  public static Chart2D.PointFinder[] values​()

  Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

  for (Chart2D.PointFinder c : Chart2D.PointFinder.values())
      System.out.println(c);
  

  Returns:

  an array containing the constants of this enum type, in the order they are declared

• valueOf

  public static Chart2D.PointFinder valueOf​(java.lang.String name)

  Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

  Parameters:

  name - the name of the enum constant to be returned.

  Returns:

  the enum constant with the specified name

  Throws:

  java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

  java.lang.NullPointerException - if the argument is null

• getNearestPoint

  public ITracePoint2D getNearestPoint​(java.awt.event.MouseEvent me,
                                       Chart2D chart)

  Default implementation always returns null.

  Specified by:

  getNearestPoint in interface IPointFinder

  Parameters:

  me - the mouse event over the chart.

  chart - to search points within.

  Returns:

  e nearest MouseEvent to the given mouse event's screen coordinates or null if no point was found / service is not implemented.
