Subject [jira] Commented: (MATH-440) Introducing a "UserException" class
Date Fri, 12 Nov 2010 18:05:13 GMT

    [ https://issues.apache.org/jira/browse/MATH-440?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12931476#action_12931476

Gilles commented on MATH-440:
-----------------------------

Luc,

I'll let you take care of removing "DerivativeException" since you said that you were going
to make changes in the "ode" package.
And I think that "IntegratorException" is also a candidate for removal.

> After a discussion in MATH-425, it was concluded that a new "UserException" could be
created and advertised as a privileged channel to convey failure information through the CM
code layer.
> The usage of this exception is the same as the one intended for the current {{FunctionEvaluationException}},
{{MatrixVisitorException}} and {{DerivativeException}}, so those classes will be deprecated.
