Subject [jira] [Created] (MATH-1307) Create a base class for all RNGs
Date Sat, 26 Dec 2015 17:34:49 GMT
Gilles created MATH-1307:
----------------------------

             Summary: Create a base class for all RNGs
                 Key: MATH-1307
                 URL: https://issues.apache.org/jira/browse/MATH-1307
             Project: Commons Math
          Issue Type: Improvement
            Reporter: Gilles
            Assignee: Gilles
            Priority: Minor
             Fix For: 4.0


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.
