Subject [jira] [Created] (MATH-714) init methods for event handler and stap handler in ODE
Date Mon, 28 Nov 2011 10:06:40 GMT
init methods for event handler and stap handler in ODE
------------------------------------------------------

                 Key: MATH-714
                 URL: https://issues.apache.org/jira/browse/MATH-714
             Project: Commons Math
          Issue Type: Improvement
    Affects Versions: 2.1
            Reporter: Luc Maisonobe
            Assignee: Luc Maisonobe
            Priority: Minor
             Fix For: 3.0


The EventHandler interface does not provide any way to initialize the step handler at integration
start.
The StepHandler interface does have this feature, but it uses a confusing name (reset) which
can easily be confused with the resetState method of the EventHandler interface despite it
has nothing to do with events based resets.

Both interfaces being often used together, it would be nice to have an init method in both
interfaces, with arguments t0, y0 and t representing the integration boundaries. The init
method would simply replace the reset method in the StepHandler interface and it would be
a new method in the EventHandler interface.
