All Implemented Interfaces:

public class Trace2DLtdReplacing extends Trace2DLtd
In addition to the Trace2DLtd this class offers the guarantee only to allow a single tracepoint with a certain x- value. If a new tracepoint is added whose x- value is already contained, the new tracepoints values will get assigned to the certain old tracepoint respecting the fact that only an additional changed y- value occurs.
The add methods increase complexity to factor n but some event - handling may be saved (no change of x and y).
Tracepoints with x- values not contained before will be appended to the end of the internal data- structure.

      protected boolean addPointInternal(ITracePoint2D p)
      Description copied from class: ATrace2D

      Override this template method for the custom add operation that depends on the policies of the implementation.

      No property change events have to be fired by default. If this method returns true the outer logic of the calling method ATrace2D.addPoint(ITracePoint2D) will perform bound checks for the new point and fire property changes as described in method ATrace2D.firePointChanged(ITracePoint2D, int).

      In special cases - when additional modifications to the internal set of points take place (e.g. a further point gets removed) this method should return false (regardless whether the new point was accepted or not) and perform bound checks and fire the property changes as mentioned above "manually".

      Overrides:
      addPointInternal in class Trace2DLtd
      Parameters:
      p - the point to add.
      Returns:
      true if the given point was accepted or false if not.
