Gilles commented on MATH-1337:
------------------------------
Adaptor available on branch "feature-MATH-1335".
> RNG: New API to old API adaptor
> -------------------------------
>
> Key: MATH-1337
> URL: https://issues.apache.org/jira/browse/MATH-1337
> Project: Commons Math
> Issue Type: Test
> Reporter: Gilles
> Assignee: Gilles
> Priority: Minor
> Labels: api, compatibility, deprecation, test, upgrade
> Fix For: 4.0
>
>
> An "adaptor" class will be provided for users who'd like to test the new RNG
> implementations (MATH-1335) before upgrading their codes to the new API.
> This class will implement the old {{RandomGenerator}} interface (but will
> delegate all the calls to the new classes); hence the only step required in
> order to use the new RNGs in existing code will be the replacement of the
> instantiations of the old RNG classes with instantiations of the adaptor.
> For example,
> {noformat}
> RandomGenerator rng = new Well19937c(9876);
> {noformat}
> could be replaced with
> {noformat}
> RandomGenerator rng = new RngAdaptor(RandomSource.WELL_19937_C, 9876);
> {noformat}
> and subsequent usage of {{rng}} would be functionally identical.
