Gilles commented on MATH-811:
-----------------------------
bq. I think an enum with three choices (increasing, decreasing, both slope
directions) is less confusing.
I think that it is more confusing; especially if we speak of "slope direction"
(a slope cannot have _both_ directions).
If we really want to reduce the concept embodied in the enum to just "slope
direction selection", it should be made clear in the name, e.g.:
{code}
public enum SlopeDirectionSelector {
INCREASING,
DECREASING,
INCREASING_OR_DECREASING
}
{code}
Then the method "getSlopeSelection" should be renamed as
{code}
SlopeDirectionSelector getSlopeDirectionSelector();
{code}
> Improve event detection by selecting g function slope

> 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_with_spaces.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.
