[jira] [Commented] (MATH-1348) Provide an adaptor that is a subclass of "java.util.Random"

["Gilles (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MATH-1348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15283619#comment-15283619 ] 

Gilles commented on MATH-1348:
------------------------------

The class referred to in this issue is {{o.a.c.m.random.JDKRandomAdaptor}}.

I think that this class should be deprecated (see its shortcomings in the Javadoc).

The "shuffle" example evoked in the description of this report is not an issue since the class proposed in MATH-1348 provides the equivalent functionality (cf. method "nextSample").

Are there any compelling reasons for providing this adaptor?

> Some utilities of the JDK require a {{java.util.Random}} as an argument (e.g. method "shuffle" in {{java.util.Collections}}.
> In order to use such utilities but with the actual RNG delegated to alternative algorithms (i.e. those provided in CM), we have to extend {{Random}}, overriding all the generation methods.
> The adaptor will be similar to {{o.a.c.m.random.RandomAdaptor}} but for {{o.a.c.m.rng.UniformRandomProvider}} instead of {{o.a.c.m.random.RandomGenerator}}.
