Method Detail

• addAdditionalPointPainter

  boolean addAdditionalPointPainter​(IPointPainter<?> pointPainter)

  Adds a point painter that additionally (to the pointer painters of the trace (ITrace2D.getTracePainters() )) paint this point.

  No clone will be taken. Outside modifications of the argument later on will also affect this instances state!

  Caution! This is a low level mechanism that is also used by the highlighting mechanism. It is being utilized by the Chart2D.enablePointHighlighting(boolean) which will use some mouse motion listener to remove outdated highlighters and add highlighters to the new point in focus by taking the highlighter configured in the trace.
  So to use point highlighting for traces you should not re-program it at this level but just use ITrace2D.addPointHighlighter(IPointPainter) and Chart2D.enablePointHighlighting(boolean).

  Parameters:

  pointPainter - a point painter that will additionally (to the trace painter of the chart) paint this point.

  Returns:

  true if this point painter was accepted (not contained before by the means of Comparable.compareTo(Object) .

• removeAdditionalPointPainter

  boolean removeAdditionalPointPainter​(IPointPainter<?> pointPainter)

  Removes a point painter that additionally (to the pointer painters of the trace (ITrace2D.getTracePainters() )) paint this point.

  Parameters:

  pointPainter - a point painter that currently is used to additionally (to the trace painter of the chart) paint this point.

  Returns:

  true if this point painter was removed (contained before by the means of Comparable.compareTo(Object) .

• removeAllAdditionalPointPainters

  java.util.Set<IPointPainter<?>> removeAllAdditionalPointPainters()

  Removes all point painters that additionally (to the pointer painters of the trace (ITrace2D.getTracePainters() )) paint this point.

  Returns:

  all instances that were used before this call.

• clone

  java.lang.Object clone()

  Returns a cloned instance (deep copy).

  Returns:

  a cloned instance (deep copy)

• getAdditionalPointPainters

  java.util.Set<IPointPainter<?>> getAdditionalPointPainters()

  Returns the point painter that additionally (to the trace painter of the chart) paint this point.

  The original list is returned so painters may be added or removed (even all painters may be cleared).

  Returns:

  the point painters that additionally (to the trace painter of the chart) paint this point.

• getEuclidDistance

  double getEuclidDistance​(double xNormalized,
                           double yNormalized)

  Returns the Euclid distance of this point's normalized values ( getScaledX(), getScaledY()) to the given normalized coordinates.

  Parameters:

  xNormalized - the normalized x coordinate between 0 and 1.0 to measure the Euclid distance to.

  yNormalized - the normalized y coordinate between 0 and 1.0 to measure the Euclid distance to.

  Returns:

  the Euclid distance of this point's normalized values ( getScaledX(), getScaledY()) to the given normalized coordinates.

• getListener

  ITrace2D getListener()

  Returns the listener trace connected to this trace point.

  Returns:

  the listener trace connected to this trace point.

• getManhattanDistance

  double getManhattanDistance​(double xNormalized,
                              double yNormalized)

  Returns the Manhattan distance of this point's normalized values ( getScaledX(), getScaledY()) to the given normalized coordinates.

  Parameters:

  xNormalized - the normalized x coordinate between 0 and 1.0 to measure the Manhattan distance to.

  yNormalized - the normalized y coordinate between 0 and 1.0 to measure the Manhattan distance to.

  Returns:

  the Manhattan distance of this point's normalized values ( getScaledX(), getScaledY()) to the given normalized coordinates.

• getManhattanDistance

  double getManhattanDistance​(ITracePoint2D point)

  Returns the Manhattan distance of this point to the given one.

  Parameters:

  point - the point to measure the Manhattan distance to.

  Returns:

  the Manhattan distance of this point to the given one.

• getScaledX

  double getScaledX()

  Returns:

  the scaledX.

• getScaledY

  double getScaledY()

  Returns:

  the scaledY.

• getX

  double getX()

  Returns the x value.

  Point2D.getX()

• getY

  double getY()

  Returns the y value.

  Returns:

  the y value.

  Point2D.getY()

• setListener

  void setListener​(ITrace2D listener)

  Allows ITrace2D instances to register (or de-register) themselves with this point to receive (or stop receiving) change information via ITrace2D.firePointChanged(ITracePoint2D, int) events.

  Parameters:
