Subject [jira] [Resolved] (MATH-1307) Create a base class for all RNGs
Date Thu, 04 Feb 2016 01:33:39 GMT


Gilles resolved MATH-1307.
       Resolution: Won't Fix
    Fix Version/s:     (was: 4.0)

> Create a base class for all RNGs
> --------------------------------
>                 Key: MATH-1307

>          Issue Type: Improvement

> I proposed to create a base class which the existing abstract classes {{AbstractRandomGenerator}}
and {{BitsStreamGenerator}} will extend.
> This would allow to define {{nextBytes(byte[])}} at the base class level.
> The code for that method is almost identical in the two hierarchies: they only differ
in a call to either {{nextInt()}} or {{next(32)}} respectively; the latter is however the
same as the former, in disguise, and is not subject to change given the type of return value.
> As a corollary, the new base class can be the unique place where to add utilities such
as the one proposed in MATH-1306.
> *Update:* {{AbstractRandomGenerator}} and {{BitsStreamGenerator}} are both obsoleted
by the class proposed in this report.
