Luc Maisonobe commented on MATH-811:
------------------------------------
I'll have a more thorough look into it when I have some time.
I have thought about that for a while, trying to find a solution as I think
this change is important to you.
There is one way we could introduce it into 3.1, but it is ugly so I am
reluctant to do it. It would imply creating an extended interface (say
FilteredSlopeEventHandler extends EventHandler) that would include the new
method and to have a runtime check in EventState using instanceof to use the
feature only if it is available. What would you think about this ugly hack?

> Key: MATH-811
> URL: https://issues.apache.org/jira/browse/MATH-811
> Project: Commons Math
> Issue Type: Improvement
> Affects Versions: 3.1
> Reporter: Yannick TANGUY
> Attachments: JIRA-811_slope_selection.patch,
> JIRA-811_slope_selection_V2.patch, JIRA-811_slope_selection_V3.patch,

>
> We would like to select g function slope in CommonsMath event detection
> feature.
> This would improve event detection for the final user (the possibility to
> ignore some events, and less computation time) and also correct a bug found
> while using OREKIT (see https://www.orekit.org/forge/issues/104) in our
> applications.
> The modification consists in adding a method (getSlopeSelection() : int) in
> EventHandler, and modifying one conditionnal in the method evaluateStep
> (class EventState).
> We can provide modified code and unitary tests for this feature.
